Temps vs PostHog

Researched and updated 2026-08-07

Fewer analytics features. No event quota.

PostHog is the deeper analytics product and its free tier is unusually generous — 1M events and 5,000 session replays a month. Temps competes on a narrower claim: analytics and replay that arrive with your deployment platform, self-host cleanly, and do not meter events.

The short answer

Choose Temps if you…

  • You want analytics and session replay included with your deployment platform
  • You expect to exceed a few hundred thousand events/month on a self-hosted install
  • You want a single binary rather than a multi-service analytics stack
  • Analytics data must stay on your own infrastructure with supported self-hosting
  • You need deployments, error tracking and uptime monitoring in the same tool

Choose PostHog if you…

  • You need funnels, cohorts, retention analysis or experiments — PostHog is much stronger
  • Feature flags or A/B testing are part of your workflow
  • You want a data warehouse and SQL access to your product data
  • You are inside the free tier and value analytical depth over bundling
  • You want a hosted product with dedicated support

Why teams switch from PostHog

No event quota when self-hosted
Temps analytics are not metered. PostHog's own docs say a self-hosted open-source deployment runs on a single machine and is "unlikely to scale past a couple 100ks events without significant effort in scaling", and their deployment guide asks whether you expect to exceed 300k events a month before recommending Cloud. A busy self-hosted install is outside what they support.
Self-hosting is the primary path
Temps is built to be self-hosted and supported that way under Apache 2.0. PostHog's open-source deployment comes with no customer support and no guarantees by their own documentation.
One binary, not a cluster
PostHog's self-hosted deployment guide asks for the equivalent of a Hetzner VM with 4 vCPU, 16GB of RAM and more than 30GB of storage, running a multi-service stack. Temps is a single Rust binary that also handles deployments, error tracking and uptime monitoring.
Analytics attached to your deploys
Because Temps ships the app and collects its analytics, a traffic change sits next to the deployment that caused it without wiring up a release annotation.

What it actually costs

PostHog's free tier is genuinely generous and most small products will never pay for it. The comparison is not really about price at that scale — it is about whether you want a deep, metered analytics suite as a separate system, or lighter analytics that come with the platform and are not metered when you run them yourself.

Migrating from PostHog

Medium difficulty

Swap the PostHog snippet for @temps-sdk/react-analytics. Pageviews and custom events map across directly, and session replay is rrweb-based on both sides. What does not map is anything built on PostHog's analysis layer — funnels, cohorts, experiments and feature flags have no Temps equivalent, so audit what your team actually depends on before switching. Historical events do not transfer.

Frequently asked questions

Is PostHog free?

PostHog's free tier includes 1M product analytics events, 5,000 web session recordings, 1M feature flag requests and 100k error tracking exceptions per month. Usage beyond that is billed per unit.

Can I self-host PostHog for free?

Yes — PostHog is MIT licensed apart from its ee directory, and a posthog-foss repository exists. Their documentation says an open-source deployment is "unlikely to scale past a couple 100ks events without significant effort", uses 300k events a month as the point to reconsider, and states plainly that self-hosted users cannot receive commercial support and that PostHog cannot help debug or recover from data loss.

Does Temps replace PostHog?

Only for pageviews, custom events, funnels and session replay. Temps has no cohorts, experiments, surveys or feature flags, and PostHog's funnel analysis is considerably deeper than ours. If any of those are central to how you work, PostHog is the right tool.
