## Amplitude

- `dev-services/amplitude` | qualifies-with-caveat | evidence documented | binding volume-quota | category product analytics with session replay, feature flags and experimentation (hosted) | tier Free
- needs card no, phone unknown, ID no, institution no | verified 2026-11-01T18:13:30.918Z (live) | stale on 2026-12-02
- url https://amplitude.com/pricing
- free tier: Free plan, forever and with no credit card required: 2M events per month, unlimited team members, 10,000 monthly session replays kept 1 month, 5,000 monthly agent sessions, 2,000 monthly AI feedback records, unlimited feature flags and 1 active experiment; analytics data is accessible for 1 year | unit: mixed | metered on: request-count | read on: 2026-11-01 | source: [1] | note: Events are the headline count; session replays, agent sessions and feedback records each have their own monthly count, so no single unit of the vocabulary fits. The FAQ states the Free plan has a fixed limit of 2 million events a month and is not a trial. Plus is described as free for the first 2M events a month but needs a credit card.
- per-object cap: the HTTP V2 API rejects a request larger than 1 MB with a 413 error, and the Free plan is advised to send no more than 10 events per batch; the Batch Event Upload API accepts up to 20 MB per request | source: [2]
- retention: 1 year of data access on Free (2 years on Plus); session replays are kept 1 month; agent session chats are kept 14 days | days: 365 | source: [1]
- egress: unverified: no export allowance or price is stated on the pricing page, which lists developer SDKs and APIs as included on every plan | metered: no | source: [1]
- identity: email | detail: The pricing page states the Free plan needs no credit card; the sign-up page asks for a work email address behind a reCAPTCHA. Any later step, such as a phone number or the choice of region, is unverified: behind a sign-up.
- interface: rest
- limits:
  - volume-quota (binding): 2M events per month on Free [1]
  - volume-quota (binding): 10,000 session replays, 5,000 agent sessions and 2,000 AI feedback records per month [1]
  - request-rate: HTTP V2 upload on Free: 100 batches per second and 1000 events per second [2]
  - per-object-cap: 1 MB per HTTP V2 request [2]
  - retention-clamped: 1 year of data access, 1 month of session replays, 14 days of agent session chats [1]
- limits note: Free keeps 10 saved charts per organization and has no webhooks.
- binding note: The fixed 2M events a month is the first ceiling for an app with traffic; the 1000-events-a-second upload rate binds only a bulk import.
- interface detail: Event ingestion through the HTTP V2 API at api2.amplitude.com (EU residency: api.eu.amplitude.com), with an API key in the JSON body, and through SDKs; an MCP server connects AI tools to Amplitude data on every plan, Free included. Webhooks are not included on Free.
- endpoint: https://api2.amplitude.com/2/httpapi
- tooling: the web and mobile SDKs, the HTTP V2 and Batch Event Upload APIs, and the web app; an MCP server for AI tools
- composes with: Product analytics for the front end of a free-hosted app, up to 2M events a month, with feature flags, one experiment and 10,000 session replays in the same project.
- reliability: no throttle, ban or data loss is stated on the pages read; user property updates past 1800 an hour for one user may be dropped while events are still ingested
- notes: Startups with under USD 10M in funding and fewer than 20 employees receive one free year of the Growth plan, a separate offer; the Plus plan starts at USD 0 for the first 2M events a month but requires a credit card.
- evidence note: Plan limits are quoted from the first-party pricing page and the API limits from its documentation; the sign-up page was read through a pinned page reader. No account was opened, so what happens past 2M events is unverified: behind a sign-up.
