Leat
Sign in Start free

Leat 1.0, deploy previews and feature flags. Free for teams of two.

Every pull request gets a live preview, and every release is a switch you can flip back.

Push a branch and Leat builds it in a median 41 seconds, then posts the link on the pull request. Flags sit beside the preview, so a feature can reach staging, a teammate or one customer before production sees it.

  • 41 s median from push to preview
  • Flags reach every SDK in under 2 s
  • 18 regions on 4 continents

Teams shipping with Leat

Teams using Leat include Pebblecart, Tidebell, Quillstone, Larkmoor, Copperwren, Brightkiln, Otterwick, Ferncast, Hollowbird and Saltgrove.

The branch, the preview and the switch, in one place.

Leat sits between your repository and your users. These are six things it does all day, shown the way they look in the app.

One command bar for all of it

Press ⌘ K and type what you want. Promote a preview, flip a flag, roll back or open the build logs without leaving the keyboard.

A status check on every pull request

The check moves from queued to ready and links straight to the preview.

The diff before the promote

Variables, flags and the build that will change, shown against production first.

Previews served near your reviewers

Every preview answers from 18 regions, so a reviewer in Lisbon waits about as long as one in Ohio. Response times sit beside every build.

Roll back in about two seconds

Production keeps its last 20 builds warm, so going back moves a pointer instead of starting a build.

Flags per environment

Turn a feature on in previews and staging first, then production. No redeploy, and every change is logged.

Off in production

“We used to take turns on staging. Now every pull request has its own preview, checkout changes wait behind a flag, and the Tuesday release is a switch someone flips after lunch.”

Free for two people, then per seat.

Reviewers who only open previews and leave comments never need a seat. Every plan builds and serves from all 18 regions.

Questions

Anything else, write to us from the app. A person who works on Leat answers, usually within a working day.

Do reviewers need a seat?

No. Anyone you invite can open a preview, leave comments and approve it without a seat. Seats are for the people who push code or change flags.

What counts as a build minute?

Wall clock time from the first install step to the last uploaded file, rounded up to the minute for each build. A restored cache is not counted twice.

Where are flags evaluated?

In your own process. The SDK keeps the rules in memory and answers in about 0.4 ms. Leat only sends rule changes, and they reach every SDK in under 2 seconds.

Can our data stay in the EU?

Yes, on Business. Builds, logs and flag events stay in Frankfurt and Dublin, and the audit log records where each one was stored.

What if we run out of build minutes?

Builds keep running. Team pays $0.006 for each extra minute, and the workspace owner gets an email at 2,400 minutes and again at 3,000.

Can we leave and take our flags with us?

Yes. Flags export as one JSON file with every rule and its history, and previews are ordinary builds you can run anywhere.
