A dev environment.
One per branch.
A native macOS app that spins up a full, isolated, runnable environment for every branch — services, databases, and shared infra, wired automatically. No YAML archaeology, no port juggling.
One branch, one full stack.
Nothing shared, nothing to tear down.
Own worktree
Every branch is a real git worktree — check out ten at once, no stashing, no context loss.
Own services & DBs
Each workspace runs its own services on its own ports with its own databases. Two branches never collide.
Conflict-free ports
Ports are allocated automatically and stay sticky while a service runs. You never hunt for a free port again.
Stop rebuilding on every switch.
Golden main, cloned in seconds.
Databases via TEMPLATE
New workspaces clone their databases from a prepared main with CREATE DATABASE … TEMPLATE — sample data included, in seconds.
node_modules, copy-on-write
Dependencies materialize from main's installed copy via APFS clone — near-instant, sharing disk blocks, keyed by lockfile hash.
Your branch's data, right in the app.
No second tool to check a row.
Browse & query
A tree of every per-branch database down to its tables. Open a table as a data grid, or run SQL in a console with syntax highlighting and schema-aware autocomplete.
Multiple engines
Inspect Postgres tables and Redis keyspaces today — with more engines on the way — over the same connection your services use, wired automatically.
Your agent can too
Claude in the workspace lists tables and queries the branch database over MCP while it builds — no copy-pasting connection strings.
Made for the checks you run constantly while coding — inspect a row, confirm a migration, tweak a query — right where you work, no separate client to wire up.
Written in Swift, not in Electron.
Here's what that gets you.
Config that writes itself.
Point it at repos; the agent does the rest.
Onboarding agent
Reads each repo, detects frameworks and services, and writes a runnable pom.yml.
Config doctor
Deterministic checks (no LLM) loop until nothing blocks the project from running.
Claude in the window
A built-in agent per workspace, wired to the environment it's working in.
Install it and open a branch.
There's nothing to sign up for.
