1 · Create a branch
Branch from Main right in the Translation Editor. Your edits live on the branch and never touch Main until merged.
Work on localization changes in isolation, pull in changes from Main on your terms, resolve conflicts clearly, and merge with a reviewed pull request - git-style, without leaving the editor.

Navigation
Work in isolated environments without affecting production data. Branch workspaces allow you to safely test new translations, experiment with AI, and request reviews before merging changes to the main branch.

How it works
Branch from Main right in the Translation Editor. Your edits live on the branch and never touch Main until merged.
Add keys, edit source copy, and translate. Every change is tracked as a branch overlay with full history.
When Main changes, pull those updates in. You decide what to adopt - nothing is forced onto your branch.
Request review from a teammate. Reviews are revision-aware: editing after approval re-opens the PR.
After approval and a clean sync, merge atomically. A version checkpoint and immutable history are recorded.
Like git or Figma branching, your branch shows the keys it started with plus the ones you add. A new key on Main doesn’t appear automatically - it waits in Update from Main so you decide whether to bring it in. When you merge, only your changes are written to Main; a key you never touched is never removed.
Update from Main
When Main has moved ahead, a banner appears above your keys. Open Update from Main to see every change grouped by type. Only true conflicts need a decision; new Main keys are a simple adopt-or-skip. Pick everything first, then apply once - nothing is committed until you click Apply updates.
A key added on Main after your branch was created. It stays hidden from your branch until you choose Add to branch. (Recommended - keeps you in sync.)
The same key was renamed differently on Main and your branch. Pick Main’s name, keep yours, or rename to something new.
Main and your branch changed the same key. Review both versions side by side and pick which to keep.
Main removed a key you edited. Choose to accept the removal or keep your version on the branch.
Both sides created the same key name as separate keys. Keep Main’s, keep yours, or rename to avoid the collision.
Isolation
Branch workspaces allow multiple teams or features to work concurrently without colliding. Just like Git branching, you can create a new branch from Main, perform all your localization tasks, review them in isolation, and eventually merge your finalized strings back to the main environment.
Syncing
If Main has advanced while you were working on your branch, you will need to update your branch to avoid divergence. The "Update from Main" feature allows you to seamlessly pull down new keys and updated source strings into your current branch so you're always working with the latest context.
Reconciliation
Conflicts occur when the same key was edited differently in Main and in your branch. StringsOS highlights these collisions and provides a clear resolution interface. You can review the incoming value from Main alongside your current branch's value, and explicitly choose which translation to keep before completing the update.
In a project with two or more members, open a pull request and request review. Authors can’t approve their own PR. Reviews are tied to the exact branch revision, so editing after approval re-opens the request. A PR can’t be created while the branch is behind Main or has conflicts.
Merge requires one current approval from another member, no requested changes, no conflicts, and a branch that’s in sync with Main. The merge runs atomically and writes a version checkpoint plus immutable history. Solo projects can merge directly - the sync and conflict gates still apply.
The branch switcher shows only active branches to keep it focused. Merged and archived branches live in the History panel, with a filter to show or hide them - so the full record is always one click away.
Branch, review, and merge translations with the same rigor as your codebase - without the friction.
