feature flags for the terminal

Flip features, not deploys.

Switchyard keeps your feature flags in your repository and flips them from the command line. Ship code dark, roll it out by percentage, and roll it back in one command.

readout

  • checkout-v2 .......... 10%
  • new-search ........... on
  • dark-mode ............ off
  • p95 flip latency ..... 40ms

yard --demo

One command per decision.

Three sessions from a normal day. Every flip is logged, reviewable, and undoable.

  1. yard flip checkout-v2 --to 10% --reason "canary"

  2. flip(checkout-v2, production)

    off → 10% of users

    logged as #482 by sam

  3. checkout-v2 is live for 10% of production. Error rate and latency are on the dashboard.

  1. yard off new-search --env production

  2. flip(new-search, production)

    on → off

    propagated to 14 regions in 38ms

  3. new-search is off everywhere. The code stays deployed; flip it back when the fix lands.

  1. yard new dark-mode --default off --pr

  2. write(flags/dark-mode.toml)

    created flags/dark-mode.toml

    opened pull request #219

  3. dark-mode is ready for review. It goes live, off, when #219 merges.

A new checkout reaches ten percent of shoppers without a deploy.

What you get

Small tool. Sharp edges where you want them.

  1. [ 0.001 ]Flags live in your repo

    Each flag is a TOML file next to the code it guards. Changes go through pull requests, so review and history come free.

  2. [ 0.002 ]One SDK call

    yard.on("checkout-v2", user) returns true or false. No clients to configure, no background threads, no surprises in your bundle.

  3. [ 0.003 ]Rollouts by percentage

    Turn a feature on for 1%, 10%, then everyone. The same user always lands on the same side.

  4. [ 0.004 ]Instant rollback

    yard off reaches every region in under 50ms. The code stays deployed; only the switch moves.

  5. [ 0.005 ]A full audit trail

    Who flipped what, when, from where, and why. Search it from the CLI or export it as JSON.

Before you install

The questions people ask first.

A switch in your code that turns a feature on or off without a deploy. Ship the code dark, then flip it on for yourself, for ten percent of users, or for everyone.

Start
