From browser to BigQuery and ad platforms - warehouse-native, and ready for AI
agents via MCP.
## The problem
GA4, custom tags, ad pixels - each one a separate setup, none of them agreeing
on the same numbers. When something breaks, you can't see where.
walkerOS is one collection layer for all of them.
## Why walkerOS?
- **Config-as-code** - version control your tracking, review it in PRs, deploy
with confidence
- **Declarative tagging** - tag your UI in HTML, not scattered JavaScript
- **Consent-native** - events queue until consent is given, then flush correctly
to every destination
- **Schema validation** - catch bad events at collection time, not weeks later
in a dashboard
- **One layer, many destinations** - send to your warehouse and ad platforms
from a single event definition
- **Warehouse-native** - events land clean and structured in your data
warehouse, ready to query
- **MIT licensed** - self-host anywhere, no vendor lock-in
## How it works
- **Sources:** Where events come from (browser, dataLayer, Express, AWS Lambda,
GCP Functions, and more)
- **Collector:** The processing engine (consent, validation, mapping, routing,
enrichment)
- **Destinations:** Where events go (GA4, Google Ads, Meta CAPI, BigQuery, and
more)
## Two ways to install walkerOS
Choose one based on your workflow and integration possibilities:
| Mode | Description | Best For |
| -------------- | ------------------------------------------------------------ | --------------------------------------- |
| **Integrated** | Import directly into your TypeScript application | React/Next.js apps, TypeScript projects |
| **Bundled** | Build a standalone script from JSON config with npx walkeros | Static sites, Docker deployments, CI/CD |
**Integrated** (import into your app):
```typescript
import { startFlow } from '@walkeros/collector';
const { elb } = await startFlow({
destinations: {
console: {
code: {
type: 'console',
config: {},
push: (event) => console.log('Event:', event.name),
},
},
},
});
await elb('page view', { title: 'Home' });
// -> logs: Event: page view
```
Wire a real source and destination once you are ready:
```typescript
import { startFlow } from '@walkeros/collector';
import { sourceBrowser } from '@walkeros/web-source-browser';
import { destinationGtag } from '@walkeros/web-destination-gtag';
await startFlow({
sources: {
browser: {
code: sourceBrowser,
config: { settings: { pageview: true } },
},
},
destinations: {
ga4: {
code: destinationGtag,
config: {
settings: { ga4: { measurementId: 'G-XXX' } },
},
},
},
});
```
**Bundled** (build from JSON config):
```json
{
"version": 4,
"flows": {
"default": {
"config": {
"platform": "web",
"bundle": {
"packages": {
"@walkeros/collector": {},
"@walkeros/web-source-browser": {},
"@walkeros/web-destination-gtag": {}
}
}
},
"sources": {
"browser": {
"package": "@walkeros/web-source-browser",
"config": { "settings": { "pageview": true } }
}
},
"destinations": {
"ga4": {
"package": "@walkeros/web-destination-gtag",
"config": {
"settings": { "ga4": { "measurementId": "G-XXX" } }
}
}
}
}
}
}
```
Then: `npx walkeros bundle flow.json`

- **[Full Documentation](https://www.walkeros.io/docs/)** - Complete guides and
API reference
- **[Destinations](https://www.walkeros.io/docs/destinations/)** - GA4, Meta,
BigQuery, and more

- **[Storybook](https://storybook.walkeros.io/)**
## AI-ready via MCP
walkerOS exposes a Model Context Protocol (MCP) interface. AI agents can read
your event schema, suggest tracking definitions, and generate integration code -
making your event layer programmable, not just configurable.
In Claude Code, one plugin installs both MCP servers and the walkerOS skills:
```
/plugin marketplace add elbwalker/walkerOS
/plugin install walkeros@elbwalker
```
For any other MCP client, add the servers to its configuration:
```json
{
"mcpServers": {
"walkeros-flow": {
"command": "npx",
"args": ["@walkeros/mcp"]
},
"walkeros-source-browser": {
"command": "npx",
"args": ["@walkeros/mcp-source-browser"]
}
}
}
```
Loading a flow, validating it, and simulating an event all run locally, no
account needed. See the [MCP docs](https://www.walkeros.io/docs/apps/mcp).
