Amplitude exposes a comprehensive self-serve API surface: ingestion, export, dashboards, cohorts, taxonomy, and privacy APIs, documented with OpenAPI and Postman. Auth is a per-project key and secret over HTTP Basic. Ingestion caps at 1,000 events/sec per project.
Amplitude scores A on the API Report Card. Amplitude exposes a comprehensive self-serve API surface: ingestion, export, dashboards, cohorts, taxonomy, and privacy APIs, documented with OpenAPI and Postman. Auth is a per-project key and secret over HTTP Basic. Ingestion caps at 1,000 events/sec per project.
Amplitude has a workable official integration path. Most engineering teams can build against it directly. Open API: self-serve, documented, with SDKs
Amplitude is the leading enterprise digital and product analytics platform, a SaaS suite for capturing, analyzing, and acting on behavioral event data across web, mobile, server, and connected products.
Vertical: Horizontal product/digital/behavioral analytics SaaS. Product managers, growth teams, data analysts, marketers, and engineers all work in Amplitude.
Amplitude is one of the top two named product-analytics platforms globally (with Mixpanel), listed in every '2026 best product analytics' comparison, NYSE-listed since September 2021 with $374M ARR in Q1 FY2026, 4,500+ paying customers, and enterprise/multi-product customers driving 77% of ARR.
Yes, for any digital business running on Amplitude, the platform holds the full behavioral source of truth: every captured event (event_type, event_properties, timestamp, session_id), every user (user_id, device_id mapping, user_properties, computed properties, predictive scores), every group/account, every behavioral cohort and segment definition, every funnel/retention/journey chart and dashboard, every experiment flag and variant assignment with statistical readouts, every session replay, and (for Activation/CDP customers) every audience syncing to downstream marketing/ad destinations.
Founded 2012 in San Francisco by Spenser Skates, Curtis Liu, and Jeffrey Wang (originally as Sonalight, pivoted to Amplitude in 2014). Raised $336M across rounds from Benchmark, Sequoia, IVP, Battery, and others.
HTTP V2 ingestion capped at 1,000 events/sec and 100 batches/sec across the entire project, large customers hit the ceiling and must implement client-side throttling. Individual user-property updates capped at 1,800 per Amplitude ID per hour, power users or bot-like flows silently get throttled with 429s. Full sourced list under Sources below.
Common alternatives include Mixpanel, Google Analytics 4, Heap (Contentsquare), PostHog, Adobe Analytics, Pendo. Graded alternatives appear under "More from the report card" below.
Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
