# PostHog > posthog.com | Developer services; 1 record: free tier, limits, identity cost and evidence. HTML https://fshy.ajam.dev/p/posthog/ | JSON https://fshy.ajam.dev/api/v1/entity/posthog.json | how to read a record: https://fshy.ajam.dev/llms-full.txt ## PostHog - `dev-services/posthog` | qualifies-with-caveat | evidence documented | binding volume-quota | category product analytics, session replay, feature flags and error tracking | tier Free - needs card no, phone unknown, ID no, institution no | verified 2026-11-02T00:37:34.248Z (live) | stale on 2026-12-03 - url https://posthog.com/pricing - free tier: Free every month, reset monthly, with or without a card on file: 1M analytics events, 5K session recordings, 1M feature flag requests, 100K exceptions, 1500 survey responses; 1 project, 1-year data retention, unlimited team members; no credit card required | unit: mixed | metered on: request-count | read on: 2026-10-30 | source: [1] | note: Each product has its own monthly count (events, recordings, flag requests, exceptions, survey responses), so no single unit of the vocabulary fits; analytics is counted in events, and one batch request can carry many events, so request-count is only the nearest metered_on term. Usage across projects shares one free allowance. On the free plan, events past the allowance are permanently dropped and feature flags return a quota-limited response, so usage stops rather than bills. - per-object cap: Events over 1 megabyte after processing are discarded; a distinct_id is limited to 200 characters | source: [2] | note: A /batch request body must be less than 20MB, with no limit on the number of events in it. - retention: Events and metadata: 1 year on a free plan (7 years on paid). Session recordings: 1 month on the free plan. Logs: 14 days by default. | source: [1] | note: After 1 year data may move to cold storage, and data past its retention period may be deleted. - egress: unverified: no egress term on the pages read; data is read back through the private API, rate limited per personal API key (240/minute and 1200/hour on analytics endpoints) | metered: no | source: [3] - identity: email | detail: An account is tied to an e-mail address: the wizard creates one from an e-mail address and a region. The pricing and sign-up pages state no credit card is required, and the allowance is the same with or without a card on file. Whether a later step asks for a phone number is unverified: behind a sign-up. - interface: rest - limits: - volume-quota (binding): 1M analytics events per month; further events are permanently dropped on the free plan [1] - volume-quota (binding): 5K session recordings, 1M feature flag requests, 100K exceptions and 1500 survey responses per month; 1 project [1] - request-rate: 240 per minute and 1200 per hour on analytics endpoints, per personal API key [3] - retention-clamped: events 1 year, session recordings 1 month on the free plan [1] - binding note: Events past 1M in a month are permanently dropped on the free plan, so the monthly event count is the first ceiling for an app with traffic; the API rate applies only to reads with a personal key. - interface detail: Public POST-only endpoints (event capture at /i/v0/e, flag evaluation at /flags) take a project token and are not rate limited; private GET, POST, PATCH and DELETE endpoints take a personal API key or OAuth. The US app host us.posthog.com answered 401 to /api/projects/ without a key. The data region (US or EU) is fixed when the account is made. - endpoint: https://us.posthog.com/api/ - tooling: PostHog SDKs, the @posthog/wizard command (run with npx), which can create the account and install the SDK, and any HTTP client with a personal API key for the private API - composes with: Event capture and feature flags for the front end of a free-hosted app, up to 1M events a month, with error tracking in the same project; over the allowance events are dropped, not billed. - reliability: Events above the free allowance are permanently dropped and feature flags return a quota-limited response. - notes: The free plan stops at its limits instead of billing, so an app sending more than 1M events a month loses the excess. Moving to pay-as-you-go needs a card and raises the project count to 6 and event retention to 7 years. - evidence note: Every limit is quoted from a first-party page, and the private API host answered 401 without a key. No account was opened; an authenticated query from a free project would move it to measured. - evidence: - [1] 2026-10-30: the free allowance resets monthly and does not depend on a card | capture: sha256:a242294a095a661ab343024d634718f5f890b22f7d1f519db728044e33ee6c27 | quote: Resets monthly.
