<div align="center"> <img src="assets/logo_1.png" alt="DevLens Logo" width="120" /> # DevLens **Intelligent codebase visualizer.** Turn any TypeScript, JavaScript, Python, Go, Rust, or Java repository into a living, queryable graph — every node carries a functional summary, a technical summary, and a security assessment.

Each node carries: - **Functional summary** — *what business purpose does this serve?* - **Technical summary** — *how does it work?* - **Security assessment** — *severity + explanation* This is the difference between an AI that re-reads your whole repo every session and an AI that already knows the architecture — architecture reviews, impact analysis, security audits, and onboarding take **minutes, not hours**. **Typical use cases:** - **Onboarding** — a developer joining a new team sees the architecture, functional/ technical summaries, modules, and gotchas in minutes, not weeks. - **Impact analysis** — *before* touching a symbol, see its blast radius: what breaks if you change it? - **Security reviews** — every node carries a severity-ranked security assessment with real reach. - **PR review** — a review packet that explains the diff's impact, tests, and security delta. - **AI agents** — give Claude/Cursor/Kilo an MCP server + skill that queries the graph instead of re-reading files. --- ## Supported languages DevLens parses **six languages with native parsers** (no AI, no regex, no tree-sitter) and understands their frameworks: | Language | Frameworks / stacks the graph understands | What gets parsed | | :-- | :-- | :-- | | **TypeScript / JavaScript** | React, Next.js (app & pages router), Express/Hono/Fastify, React Router, TanStack Router, any Node | components, hooks, state stores, classes, methods, functions, routes | | **Python** | FastAPI, Flask, Django (+DRF), SQLAlchemy / Django ORM, Celery, Pydantic | classes, methods, functions, routes, data models | | **Java** | Spring Boot (controllers, JPA, Spring Data repositories) | classes, methods, interfaces, enums, routes | | **Go** | net/http, Gin, Echo, chi, Fiber, GORM, database/sql | structs, interfaces, methods, functions, routes | | **Rust** | axum, actix-web, rocket, utoipa, Diesel | structs, enums, traits, impl blocks, methods, functions, routes | Each repo is analyzed with its language's own parser (Python `ast`, JavaParser, Go `go/ast` + `go/types`, Rust `syn`, TS compiler API), so edges are **real** — type-checked interfaces (`IMPLEMENTS`), framework routes (`HANDLES`), and ORM data layers (`READS_FROM`/`WRITES_TO`). --- ## Prerequisites | Requirement | Needed for | Notes | | :-- | :-- | :-- | | [Bun](https://bun.sh) ≥ 1.x | Build & run from source (`bun install`, `bun run dev`, `bun start`) | macOS/Linux/Windows | | [Node.js](https://nodejs.org) ≥ 18 | `npm install -g @devlensio/cli` (optional path) | not needed for the standalone binary | | `git` | analyzing a repo (DevLens shells out to `git`) | required on all install paths | | A JVM 17+ | Java analysis | only when analyzing Java repos | | `python3` 3.11+ | Python analysis | only when analyzing Python repos | | An LLM provider API key | AI summaries (optional) | needed only for `--summarize`; structure-only analysis works offline | Summaries are **never generated silently** — the CLI and skill ask permission first, and structure-only analysis needs no provider at all. --- ## Quick Start The fastest way to try the **full experience (Web UI + CLI + hot reload)** is to clone and run from source. The one-line installers give you the CLI with zero build time. ### Option A — Clone & develop (Web UI + CLI together, recommended) ```bash git clone https://github.com/devlensio/devlensOSS.git cd devlensOSS bun install # Development (backend on :3000, hot-reloaded frontend on :3001) bun dev # OR production — one command, API + Web UI on a single port (:3000) bun start ``` Production `bun start` builds the frontend **only the first time** (later runs skip the rebuild unless you pass `--rebuild`) and serves the Web UI *and* the backend API on one port. Open the printed URL, paste an absolute repo path, and click **Analyze** (enable the skip summaries checkbox if you don't want summaries). ### Option B — Install the CLI from npm ```bash npm install -g @devlensio/cli ``` ### Option C — Install the standalone binary (no Node.js required) The installers are verbose — they print progress, warnings, errors, and next steps, and **automatically add `devlens` to your `PATH`** (your shell's rc file on macOS/Linux, your user `PATH` on Windows). ```bash # Linux / macOS curl -fsSL https://raw.githubusercontent.com/devlensio/devlensOSS/main/scripts/install.sh | sh # Windows (PowerShell) irm https://raw.githubusercontent.com/devlensio/devlensOSS/main/scripts/install.ps1 | iex ``` Customize with environment variables: `DEVLENS_VERSION` (e.g. `v0.5.1`), `DEVLENS_INSTALL_DIR` (install folder), or `DEVLENS_NO_PATH=1` to skip the automatic PATH setup. ### Using any install — summarize, then explore ```bash cd your-project devlens init # optional — configure your AI provider for summaries devlens analyze . --summarize # build the graph + generate AI summaries devlens overview # language, framework, stats, central nodes devlens find-nodes -t ROUTE # every route in the app devlens architecture # one-command architecture brief devlens security # security flags across the codebase ``` Want it in your AI agent instead? Jump to [Agent Skill](#agent-skill--ai-powered-understanding). --- ## Screenshots <div align="center"> <img src="assets/screenshot-graph.jpg" alt="Interactive graph explorer" width="48%" /> <img src="assets/screenshot-node.jpg" alt="Node inspector with summaries & security risk" width="48%" /> <br/><br/> <img src="assets/screenshot-subgraph.jpg" alt="Focused node subgraph" width="48%" /> <img src="assets/screenshot-security.jpg" alt="Security findings" width="48%" /> <br/> <em>Interactive graph explorer · node inspector with AI summaries & security risk · focused node subgraph · security findings</em> </div> --- ## Why it's fast & cheaper A node summary is **~50 tokens**. The file it describes is **~2,000**. Querying summaries and graph slices (`get_blast_radius`, `get_subgraph`) costs a fraction of reading files — humans get answers faster, and AI agents spend dramatically fewer tokens on the same task. --- ## Ways to use DevLens Pick the interface that fits your workflow: ### <img src="assets/web-icon.svg" width="20" style="vertical-align: middle" /> Web UI — visual exploration *For when you want to see your codebase laid out as an interactive graph.* Open the Web UI, paste your repo path, and explore a force-directed canvas — click any node to see its summaries, callers, callees, and security flags. Search, filter, diff commits across versions. The UI runs on a **live server**, so opening `/graph/<any-new-id>` (e.g. clicking a repository card) always renders the graph — even for repos analyzed after the server started. ```bash # Production — one command, UI + API on one port (from the source repo) bun run start # → Web UI: http://localhost:3000 ``` Or from source (see [Quick Start](#quick-start)): `bun run dev` (hot reload) or `bun run start` (production). The Web UI runs from the source tree — it is **not** bundled into the installed CLI binary. ### <img src="assets/cli-icon.svg" width="20" style="vertical-align: middle" /> CLI (`@devlensio/cli`) — terminal power *For scripts, CI, and answers fast without leaving the terminal. Every command supports `--json` for piping into scripts, `-v/--verbose` for diagnostics, and `--quiet` for minimal output.* ```bash npm install -g @devlensio/cli ``` **Analyze & summarize** | Command | What it does | |---------|--------------| | `devlens detect [path] [--deps]` | Inspect a repo **before** analyzing: language, manifest, dependency count, source files | | `devlens analyze [path] [--summarize] [--force-summarize]` | Build the graph (optionally add AI summaries) | | `devlens summarize [target]` | (Re)generate technical/business/security summaries (`target` = repo path or graph id) | | `devlens status` | Which repos are analyzed, their language + summary coverage | | `devlens doctor` | Environment health check — git, storage, LLM provider, and **all 4 extractor runtimes** (go/rust/java/python) | | `devlens init` | First-time setup — configure the LLM provider interactively | **Explore & understand** | Command | What it does | |---------|--------------| | `devlens overview` | Big picture — language, framework, stats, central nodes | | `devlens top-nodes [-l <n>]` | Highest-scoring (most central) nodes | | `devlens find-nodes <name> [-t <type>]` | Search by name / type / file / severity (e.g. `-t ROUTE`, `-t CLASS`, `-t STRUCT`) | | `devlens nodes-in-path <path>` | All nodes in a file or folder | | `devlens get-node <id>` | Full detail for one node — summaries, callers, callees | | `devlens get-summaries <ids…>` | Batch-read summaries for multiple nodes | | `devlens node-code <id>` | Raw source for a node (expensive — prefer `get-node`) | | `devlens architecture` | One-call architecture brief — modules, routes, flows, health | | `devlens onboard-tour` | One-call onboarding skeleton — modules, routes, flows, glossary, gotchas | | `devlens get-context <query>` | Token-budgeted context packet for an agent | **Impact & quality** | Command | What it does | |---------|--------------| | `devlens blast-radius <id>` | What breaks if I change this?

(cheap) devlens analyze ./my-app --summarize # build graph + AI summaries devlens find-nodes -t ROUTE # every route in the app devlens find-nodes Button # find a component by name devlens blast-radius "src/auth/login.ts::login" # what breaks if I change it? devlens security --min-severity high # critical security only devlens graphs list # stored graphs devlens graphs delete abc-123 # remove a graph ``` > **Full reference:** [`src/cli/README.md`](src/cli/README.md) — every command with options and examples. ### <img src="assets/skill-icon.svg" width="20" style="vertical-align: middle" /> Agent Skill — AI-powered understanding *The most powerful way to use DevLens. Your AI agent normally reads files one at a time — the DevLens Skill teaches it to query the pre-built graph instead.* ```bash npx @devlensio/skill install ``` Then reload your tool and use `/devlens` in Claude Code, Cursor, Kilo, opencode, pi, or any AI coding agent: | Command | What it does | |---------|--------------| | `/devlens init` | Connect MCP, configure provider, analyze the repo | | `/devlens architecture` | Full system brief — stack, modules, routes, patterns, security posture | | `/devlens explain [path]` | Onboard to a module or the whole repo — callers, callees, reading path | | `/devlens diagram [type]` | Mermaid diagrams (architecture, cluster, flow, deps) with typed edges | | `/devlens security-analysis [level]` | Prioritized security report with reach + fix-order | | `/devlens impact <symbol>` | Blast radius — what breaks if you change this? | | `/devlens tech-debt` | Cycles, coupling hotspots, god-files | | `/devlens guard [target]` | Warn before editing high-risk code | | `/devlens onboard` | Write a saved `ONBOARDING.md` for new devs | | `/devlens find <name>` | Locate any component, class, function, struct, or route | | `/devlens summary <kind> <target>` | On-demand technical / functional / security summary | | `/devlens changes [range]` | Explain recent work or a merge conflict, by functionality | > **Full reference:** [`packages/skill-installer/README.md`](packages/skill-installer/README.md) — all subcommands, install options, and supported AI tools. ### <img src="assets/cli-icon.svg" width="16" style="vertical-align: middle" /> MCP Server — for any MCP-compatible AI agent *Wire DevLens into any MCP client (Claude Code, Claude Desktop, IDE agents, …). The server is bundled inside the CLI and exposes **21 tools** covering discovery, search, traversal, security, and one-call workflow summaries.* ```bash devlens mcp # stdio mode claude mcp add devlens -- devlens mcp # register in Claude Code devlens mcp http -p 7000 # HTTP mode ``` Your agent can: list analyzed repos, get a repo overview, find nodes by name/type/severity, read summaries, trace blast radius / k-hop / subgraphs, find cycles, analyze a new repo, compare commits, and generate whole-packet **architecture/security/PR-review/onboarding/context** outputs from one call. > **Full reference:** [`src/mcp/README.md`](src/mcp/README.md) — tool catalog, registration, configuration. --- ## How to summarize Summaries are per-node AI descriptions that make querying much richer. To generate them: ```bash # During analysis (recommended) devlens analyze . --summarize # Later, for a repo or a specific graph devlens summarize . # summarize the current directory's repo devlens summarize <graphId> # summarize a stored graph # Re-generate even if already summarized (force) devlens summarize . --force-summarize # Choose a model / provider per-run (overrides saved config) devlens summarize . --provider openai --provider-name deepseek --model deepseek-v4-flash ``` You'll be asked to confirm before tokens are spent — summaries are never generated silently. Configure your provider once with `devlens init` (or `devlens config`) and it's remembered for all future runs. --- ## Configuration Config lives in `~/.devlens/config.json` and is set via `devlens init` or `devlens config`. | Provider | Recommended model | Notes | | :-- | :-- | :-- | | Ollama (local) | `qwen2.5-coder:7b` | Free, local, 8 GB+ RAM | | OpenAI | `gpt-4o-mini` | Fast, cost-effective | | Anthropic | `claude-haiku-4-5` | Best cost/quality for summaries | | DeepSeek | `deepseek-v4-flash` | Strong code model | | OpenRouter | `deepseek-v4-flash` or `mimo-v2.5` | Best cost/quality balance | | Gemini | `gemini-2.0-flash` | Fast, large context | ```bash # Interactive setup — picks from a catalog and fetches live model lists devlens config --set # Non-interactive scripting devlens config --provider openai --provider-name deepseek --model deepseek-v4-flash --api-key <key> # Switch between saved providers without re-entering credentials devlens config --active openai:deepseek # Health check devlens doctor ``` Models are discovered dynamically from each provider's `/models` endpoint — no hardcoded model lists. Custom OpenAI- or Anthropic-compatible endpoints can be added through the interactive flow. --- ## What DevLens understands **Node types (per language — a graph is per-repo/per-language):** | Language | Node types in the graph | | :-- | :-- | | TS / JS | `COMPONENT`, `HOOK`, `STATE_STORE`, `UTILITY`, `CLASS`, `METHOD`, `FUNCTION`, `ROUTE`, `FILE`, `TEST`, `STORY`, `THIRD_PARTY` | | Python | `CLASS`, `METHOD`, `FUNCTION`, `ROUTE`, `FILE`, `TEST`, `THIRD_PARTY` | | Java | `CLASS`, `METHOD`, `INTERFACE`, `ENUM`, `ROUTE`, `FILE`, `TEST`, `THIRD_PARTY` | | Go | `STRUCT`, `INTERFACE`, `METHOD`, `FUNCTION`, `ROUTE`, `FILE`, `TEST`, `THIRD_PARTY` | | Rust | `ENUM`, `STRUCT`, `TRAIT`, `IMPL_BLOCK`, `METHOD`, `FUNCTION`, `ROUTE`, `FILE`, `TEST`, `THIRD_PARTY` | Every node carries: importance score + functional summary + technical summary + security assessment (when summarized). NOTE: When a repo is re-summarized only the nodes without summaries are being summarized (incremental summarization) unless force-summarization is done. Thus saving unnecessary token consumption. **Edge types (the connections the graph draws):** `CALLS`, `IMPORTS`, `READS_FROM`, `WRITES_TO`, `PROP_PASS`, `EMITS`, `LISTENS`, `WRAPPED_BY`, `GUARDS`, `HANDLES`, `TESTS`, `USES`, `NEXTJS_API_CALL`, `NAVIGATES_TO`, `IMPLEMENTS` (class → interface / trait / ABC), `EXTENDS` (class → base class). `EXPORTS` and `THROWS` + node types `MODULE`/`PACKAGE` are **reserved** for future languages. **Router awareness — routes are real graph nodes:** Next.js (app & pages), React Router / TanStack Router / wouter, Express / Fastify / Hono / Koa, Django URLconf / DRF, Flask blueprints, `@RestController` (Spring), Gin / Echo / chi / HTTP handlers, axum / actix / rocket. --- ## Benchmarks *Tested across real-world tasks — architecture understanding, feature implementation, and bug finding — comparing the same model (DeepSeek V4 Flash, GLM 5.2, Kimi K2.6, Qwen 3.6) with and without DevLens.* ### Architecture understanding (full DevLens MCP) <div align="center"> <img src="assets/01_arch_metrics.png" alt="Architecture benchmark — cost, tokens, steps comparison" width="90%" /> </div> | Metric | Without DevLens | With DevLens | Improvement | |--------|:--------------:|:------------:|:-----------:| | Avg cost per query | $0.163 | **$0.075** | **54% cheaper** | | Avg input tokens | 88,980 | **35,035** | **61% less** | | Avg output tokens | 9,549 | **3,233** | **66% less** | | Avg tool steps | 14.3 | **7.8** | **45% faster** | | Structured output | 50% | **100%** | **2× more reliable** | | Architectural debt found | 0% | **50%** | **Now discoverable** | > Even the strongest tested model was **81% cheaper** ($0.0035 vs $0.0185) and used **83% fewer input tokens** with DevLens. --- ## Who is this for - **Developers & teams** — onboard devs in hours not weeks, review PRs with impact context, catch circular deps and god-files, keep living documentation. - **Engineering leaders** — bird's-eye architecture view, spot debt before it becomes a crisis, understand work across repos. - **AI-augmented developers** — stop letting your agent burn tokens re-reading files; it queries the graph instead. --- ## How DevLens compares DevLens is the **only tool in this space** that combines three things: native semantic parsing (not regex or tree-sitter), per-node AI summaries with per-node security analysis, and framework-aware data edges (routes, ORM reads/writes). That combination is what makes it uniquely suited for AI agents working inside a single codebase — and it's the only option you can use commercially under AGPL. Every alternative trades away at least one of those capabilities: | Dimension | **DevLens** | **Graphify** | **GitNexus** | **Sourcegraph** | **DeepWiki** | | :-- | :-- | :-- | :-- | :-- | :-- | | Core idea | Prebuilt semantic graph + per-node AI summaries + security | Syntactic knowledge graph + community detection | Agent-focused knowledge graph + taint analysis | Code search + AI assistant (Cody) | AI-generated docs per repo | | Parsing depth | **✅ Native semantic parsers** (TS compiler, Python `ast`, `go/types`, JavaParser, `syn`) — type-resolved | tree-sitter (syntactic, no type info) | tree-sitter + native bindings (no type info) | SCIP/LSIF symbol index + language servers (no semantic parse) | LLM reads source directly (no structured parser) | | Edge quality | **✅ Type-checked `IMPLEMENTS`/`EXTENDS`**, framework **routes** (Next.js/Django/Spring/Gin/axum), **ORM data edges** (`READS_FROM`/`WRITES_TO`) | `EXTRACTED`/`INFERRED`/`AMBIGUOUS` tags — no type or framework awareness | call chains, clusters, processes, `route_map` — no ORM/data edges | Precise symbol cross-references (SCIP) — no type-checked inheritance | Docs-level relationships (no structured graph) | | Per-node AI summaries | **✅ Technical + business + security** with severity — every node carries all three | ❌ (LLM used for docs/concepts) | ❌ (embeddings for semantic query) | ✅ Via Cody (hover + inline docs — chat-level, not per-node graph summaries) | ✅ Auto-generated docs per symbol (no security, no technical/business split) | | Security analysis | **✅ Per-node severity + blast-radius reach** — real exploit descriptions, not just flags | ❌ | Partial (opt-in PDG/taint — not built-in) | ❌ (SOC 2/ISO 27001 *compliance* only — no code-level findings) | ❌ | | Agent / MCP integration | CLI + **21-tool MCP** + `/devlens` skill + Web UI | CLI + local skill (no MCP) | CLI + 17-tool MCP + skills + hooks (`AGENTS.md`) | MCP server (cross-repo search + Cody agent — not a per-repo graph query surface) | Unknown (no public MCP integration) | | Language coverage | TS/JS, Python, Java, Go, Rust — **native parsers for each** | 12 code families + docs/images (shallow syntactic) | Many via tree-sitter (Dart/Kotlin/Swift…) — shallow syntactic | 30+ (via language servers — symbol-level, no semantic edges) | Any (LLM reads source — no structured extraction) | | License / pricing | **✅ AGPL-3.0 — free, including commercial use** | Apache-2.0 | PolyForm Noncommercial (**cannot use commercially**) | Open-source core; **Enterprise paid** (cross-repo search) | Free for public repos; enterprise tiers unlisted | | Multi-user cloud | In development (waitlist open) | No | Enterprise SaaS (paid) | Sourcegraph Enterprise (hosted, paid) | Web-hosted for public repos | **Other notable alternatives:** CodeSee (service-level dependency mapping, enterprise-only), CodeQL (GitHub-native semantic security analysis — deep but no AI summaries or graph visualization), and ctags-based indexers (lightweight symbol indexes, no graph intelligence). **Why teams choose DevLens over the others:** - You get **semantic edges** (type-checked inheritance, ORM data flow, framework routes) that syntactic tools like Graphify and GitNexus simply can't produce — so your agent doesn't guess relationships, it knows them. - You get **per-node security analysis** that no other open-source tool provides — not Sourcegraph (which only has compliance certifications), not GitNexus (which has optional PDG, not built-in), not DeepWiki (which ignores security entirely). - You get **21 MCP tools + a universal `/devlens` skill** — a tighter, more purpose-built agent surface than Sourcegraph's general-purpose MCP or GitNexus's hooks.
