Features

Everything that makes Critique great

If you've used Critique, Twigg will feel familiar on day one.

small CLs<br>stacked commits

Small,<br>dependent changes

Ship work as a<br>stack of small commits that build on each other. Each one is reviewed and merged<br>independently.

cl/67<br>c/67v0, c/67v1, ...

Stable<br>versioned identifiers

When a commit<br>is pushed to the server, it gets a number: c/67v0. Amend it, push<br>it, and c/67v1 is<br>created. No version is ever lost.

snapshots<br>commit versions

Iterate<br>under review

Address<br>feedback by pushing a new version of the same commit. Reviewers see the changes and how they<br>evolved, version to version.

code ownership<br>OWNERS files

Hierarchical<br>ownership

Declare who<br>owns each part of the repo. Ownership cascades down directories.

presubmits / rollouts<br>built-in CI/CD

Tests on<br>every commit

Path-aware jobs<br>run on every commit, with unlimited minutes.

patch in a CL<br>tw pull c/67

Easy<br>multiplayer

tw pull c/67, tw amend, tw push: that's all it<br>takes to contribute to someone else's commit.

branches · unfinished rebase<br>gone

Simpler than<br>Git

Commits and<br>commit versions: that's it. No branches, no staging areas, no unfinished rebase states.

gradual adoption<br>git mirror

Risk-free to<br>try

Submitted<br>changes are automatically pushed to your mirrored Git repo, so switching off<br>costs nothing.

Twigg is open source. Read it, host it,<br>contribute to it.

About us

An Open Source, bootstrapped company

We're a<br>bootstrapped company: we fund the project with services and our paid hosted instance.

Twigg is fully open source: even if we all vanish in the AI<br>apocalypse, the project will survive. Anyone (or anything) can modify, extend, and self-host<br>Twigg.
