The product

A stateless endpoint that accepts the Segment-style HTTP tracking protocol. It checks the source’s write key, validates the batch, applies rate limits and answers only after the events are durably stored.

The router turns each event into one delivery job per enabled connection, after dedupe. Workers claim jobs, call the destination’s adapter and record the outcome: delivered, retrying, failed or dead.

The archiver writes every accepted event to S3-API object storage, which is what replays and backfills read from.

A web app where members manage their workspace: sources and their write keys, destinations and their settings, connections and their rules, members and roles, and the audit log. SDK setup snippets for each source are on its page.

Every process exposes Prometheus metrics, and the repository ships alert rules, a Grafana dashboard and runbooks for the failure modes it knows about: a backlog, an open circuit, dead letters, a rate-limited source.
