feat: add anonymous analytics self-hosted by konsalex · Pull Request #405 · gethopp/hopp

konsalex · 2026-11-06T12:21:59Z

Clients pointed at a self-hosted backend never sent PostHog events, so we couldn't tell how many self-hosted teams and users exist. This adds a self_hosted_analytics event, sent on app start and then every 30 minutes.

Payload

team_hash: SHA-256 of the backend host plus the team ID (added the backnd, as team ID will be always incremental and start from 1)
user_hash: SHA-256 of the user ID
instance_hash: SHA-256 of the backend host
team_size: teammates + 1
app_version, os

Behavior

Only runs when a custom backend URL is set and it differs from the cloud URL (compared after normalizing with new URL().host).
Skipped when "Send anonymous telemetry" is off. The existing PostHog opt-out already covers this, so there's no extra check.
Waits for the user and teammates to load before sending.

PS: I avoided adding a dependency for hashing, I can see crypto.subtle has wide support, so there shouldn't be any issues

Summary by CodeRabbit

Chores
- Self-hosted app instances now periodically send analytics containing hashed server and team identifiers, team size, app version, and operating system. Sending requires a signed-in user and loaded team data; failures are logged.

Walkthrough

The main window now starts a self-hosted analytics hook. The hook checks client and team state, hashes host and identity values, and sends an event immediately and every 30 minutes. Host normalization and self-hosted detection support these checks.

Changes: Self-hosted analytics

Layer / File(s)	Summary
Self-hosted host detection `tauri/src/constants.ts`	Host normalization and comparison identify whether a custom server URL differs from the default API host. `Constants` exposes the normalized active host and self-hosted status.
Analytics capture and app wiring `tauri/src/lib/selfHostedAnalytics.ts`, `tauri/src/windows/main-window/app.tsx`	The hook checks self-hosted status, user ID, and teammate state before capturing an event. It includes hashed host and identity values, team size, app version, and OS. The main window invokes the hook.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: Moderate · up to a2b02

The new self-hosted analytics event could occasionally be sent at startup before a disabled telemetry setting takes effect. This is a narrow timing window, but it touches privacy expectations. Gate the capture on the resolved telemetry setting before merging.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Include the backend host in user_hash.

If a user ID is reused after a self-hosted instance moves to another host, this expression produces the same hash for both hosts. That permits cross-instance correlation and conflicts with the PR’s host-scoped hashing objective. Hash user:${host}:${user.id}, as the team hash does.

Wait for the telemetry setting before the startup capture.

If native telemetry is disabled but PostHog has no persisted opt-out, the user and teammates can load before the asynchronous settings check finishes. This capture can then send the self-hosted identifiers despite the disabled setting. The provider checks get_user_settings in an async loaded callback, and PostHog 1.356.1 does not await that callback; its default is to allow capture. Gate this event on the resolved setting, or initialize capture as opted out until the setting is known. (raw.githubusercontent.com)
