Understand what gets shipped.

Echo is a changelog generator that turns one release into automated release notes for four audiences.

Apps aren’t single-repo. Releases aren’t either.

Echo traces related changes across repositories: call graphs, queue topics, implicit contracts. They land as one release event, one story.

One release, four changelogs

How Echo generates your changelog.

  1. 1
    A freight elevator standing open at night in an office loading bay, one crate inside

    A release lands

    Echo reads the commits, the pull requests, and the issues they close.

  2. 2
    A wide desk at dawn under one lamp, printed pages fanned out across it

    Echo works out what changed

    Not which files moved. What it means to someone who never saw the code.

  3. 3
    Four lit windows across separate buildings in a city at dawn, seen from a rooftop

    Four changelogs go out

    Automated release notes for the team, customers, developers, and agents.

One release, four stories

Every audience gets their version.

Team

Who shipped what and why, straight from the diff.

Customers

A friendly what's-new for the people who click the buttons, not the ones who build them.

Developers

Breaking changes, API diffs, migration notes. The version you wish every tool had.

AI agents

Structured and versioned. Your changelog becomes context any agent can consume.

Proudly made with love.

Built between releases, about releases.

Keep building. We’ll tell the world.
