Free tier available

Free tier available

Usage-based pricing per product with a substantial free tier; most small teams stay free indefinitely.

Growth now starts at $0 and scales with event volume up to 20M events a month, with the first million free; annual billing saves around $480 a year. Enterprise is quote-based. Event-volume pricing stays generous for early products but climbs with a chatty event schema.

Large monthly free allowance across every product, plus free self-hosting.

Free forever, up to 1M events a month.
