This connector syncs your agent sessions, browser sessions, profiles, workspaces, and per-session agent messages into the PostHog Data warehouse, so you can analyze agent runs, step counts, token usage, and costs alongside the rest of your data. ## Prerequisites You need a Browser Use Cloud account with an API key. Keys are created self-serve and don't expire. ## Adding a data source 1. In PostHog, go to the [Sources tab](https://app.posthog.com/data-management/sources) of the data pipeline section. 2. Click **\+ New source** and click **Link** next to this source. 3. Enter your credentials (see [Configuration](#configuration) below) and click **Next**. 4. Select the tables you want to sync, choose a sync method and frequency, then click **Import**. Once the syncs are complete, you can start querying this data in PostHog. When linking Browser Use, you'll need: - **API key** – create one at [cloud.browser-use.com/settings](https://cloud.browser-use.com/settings). Keys are prefixed `bu_`. ## Sync modes Each table can be synced in one of several modes, depending on what the source supports: - **Webhook** (when available) – the source pushes changes to PostHog in real time. Fastest freshness, lowest ongoing cost, and the only mode that reliably captures updates and deletes. - **Incremental** – only new or updated rows are synced on each run, using a cursor field (such as an `updated_at` timestamp). Cheaper than a full refresh, but deletes aren't captured. - **Append only** – new rows are appended using a cursor field; existing rows are never updated. Ideal for immutable, append-only tables like event logs. - **Full refresh** – the whole table is reloaded on every sync. Use it when a table has no reliable cursor or when you need deletions reflected. See [sync methods](https://posthog.com/docs/data-pipelines/sources.md#sync-methods) for a full explanation of how each mode works and how to choose between them. Browser Use's v3 list endpoints don't support server-side time filtering, so every table syncs with full refresh. ## Configuration | Option | Type | Required | | --- | --- | --- | | `API key` | password | Yes | ## Supported tables | Table | Description | Sync method | Incremental field | Primary key | | --- | --- | --- | --- | --- | | `sessions` | A hosted agent session on Browser Use Cloud, with its status, task, and the workspace it belongs to. | Full refresh | — | — | | `runs` | An individual agent run on Browser Use Cloud (v4), with its model, status, result, token usage, and cost. | Full refresh | — | — | | `browser_sessions` | A hosted browser instance backing agent runs, with its start/finish timestamps, proxy usage, and costs. | Full refresh | — | — | | `profiles` | A reusable browser profile that persists cookies and browsing state across agent sessions. | Full refresh | — | — | The `session_messages` table fans out one request per session, so it's off by default. Enable it only if you need per-step agent messages, since it makes many more API calls than the session-level tables. ## Troubleshooting - If the connection fails with an authentication error, confirm the API key is valid and hasn't been revoked in your [Browser Use account settings](https://cloud.browser-use.com/settings), then reconnect. If your sync is failing or data looks wrong, see the [Data warehouse troubleshooting guide](https://posthog.com/docs/data-warehouse/troubleshooting.md).
