App sanity check
|
| Criteria | Result | Description |
|---|---|---|
| App builds and runs | Yes | Valid Astro component structure, correct is:inline usage |
| Preserves existing env vars & configs | Yes | No existing configs modified destructively |
| No syntax or type errors | Yes | All inline JS and Astro syntax is valid |
| Correct imports/exports | Yes | PostHog component correctly imported in Layout |
| Minimal, focused changes | Yes | All changes relate to PostHog integration |
| Pre-existing issues | None | — |
Issues
- Missing ViewTransitions re-initialization guard: The app uses
<ViewTransitions />fromastro:transitions, which causes client-side navigation that can re-execute inline scripts. The PostHog docs explicitly recommend wrapping the snippet withif (!window.__posthog_initialized)to prevent stack overflow errors. This guard is missing. [CRITICAL]
Other completed criteria
- Environment variables documented in
.env.examplewith correctPUBLIC_prefix for Astro posthog-jsadded to package.json dependencies- Build configuration remains valid
PostHog implementation ⚠️
| Criteria | Result | Description |
|---|---|---|
| PostHog SDKs installed | Yes | Both posthog-js in package.json and HTML snippet in posthog.astro (redundant but not broken) |
| PostHog client initialized | Yes | Snippet initializes via window.posthog.init() with env vars and is:inline directive |
| capture() | Yes | 6 meaningful capture calls via inline onclick handlers |
| identify() | No | No identify implementation anywhere in the app |
| Error tracking | Yes | capture_exceptions configured with capture_unhandled_errors: true and capture_unhandled_rejections: true |
| Reverse proxy | No | api_host points directly to PostHog host, no proxy configured |
Issues
- Missing ViewTransitions initialization guard: Per PostHog's Astro docs, when using
<ClientRouter>/<ViewTransitions>, the snippet must be wrapped inif (!window.__posthog_initialized)and should setcapture_pageview: 'history_change'. Without this, PostHog will be re-initialized on every soft navigation, potentially causing stack overflows and duplicate pageview events. [CRITICAL] - No reverse proxy: Client-side events sent directly to PostHog host will be blocked by ad blockers. A reverse proxy should be configured. [MEDIUM]
- No identify() call: No user identification is implemented. While this is a static marketing site with limited auth, the integration should at minimum document how to add identification. [MEDIUM]
- Redundant posthog-js in package.json: The snippet approach loads PostHog from the CDN, so the
posthog-jsnpm package inpackage.jsonis unused. Not harmful but unnecessary. [LOW] defaultsdate is outdated: Uses'2026-01-30'instead of the latest'2026-05-30'documented in PostHog docs. [LOW]
Other completed criteria
- API key loaded from environment variable (
PUBLIC_POSTHOG_PROJECT_TOKEN) - Host correctly loaded from environment variable (
PUBLIC_POSTHOG_HOST) - Uses
is:inlinedirective as required for Astro - PostHog component placed in Layout for all pages
- Development-mode error thrown for missing env vars

PostHog insights and events ✅
| Filename | PostHog events | Description |
|---|---|---|
posthog.astro |
captureException (auto) |
Automatic error tracking for unhandled errors and rejections |
index.astro |
trial_cta_clicked, documentation_cta_clicked |
Tracks hero section CTA engagement with location property |
pricing.astro |
pricing_plan_cta_clicked |
Tracks pricing plan selection with plan and cta_label properties |
Navigation.astro |
navigation_get_started_clicked |
Tracks nav bar CTA click with location property |
Issues
None — events are well-structured for this use case.
Other completed criteria
- Events represent real user actions (CTA clicks on marketing pages)
- Events enable product insights (can build conversion funnels: page view → CTA click → trial signup)
- Events include contextual properties (
cta_location,plan,cta_label) - No PII in event properties
- Event names are descriptive and use consistent snake_case naming
