Run Cline from anywhere

Every Cline session gets its own git worktree, its own Postgres, its own ports. Parallel agents never fight over your dev database — and you keep coding in yours.

Keep coding in your worktree
while Claude works in its own.

No shared database, no port collisions — isolated by default.

Loved by developers

What developers are saying about thinslice + Cline.

Every slice has its own everything

thinslice binds each git worktree to its own bag of state — no shared databases, no shared ports, no shared config. Cline runs inside a slice and can't reach yours.

One command to launch

Spin up a fresh worktree with cloned state and hand it to Cline in one shot. thinslice handles the postgres clone, the redis snapshot, and the port reservation — you just describe the task.

Review, preview, ship

When Cline is done, review the diff inline, run your app against the isolated database, then commit and open a PR — without ever touching your main working tree.

Forget about ports

When Cline sessions run in parallel, each slice gets its own reserved port range. No conflicts, no guessing which process is on which port.

Fully scriptable

Everything you can do interactively, you can do from a script or CI pipeline.

slice tmp --from current -- claude -p "implement user authentication"slice tmp --from current --name feature-x -- claude -p "implement feature X"slice ls                                          # list running slicesslice status feature-x                        # check a sliceslice rm feature-x                            # tear down + clean state

FAQ

+Is this free?
Yes. thinslice is free and open source. You need Cline installed in VS Code with your own API key or provider credentials. thinslice only manages the local worktree and state — your API usage goes through Cline as normal.
+Does my code or data leave my machine?
No. thinslice runs entirely locally. It clones your Postgres database using native copy-on-write snapshots, binds a port range to the slice, and runs Cline as a subprocess. Nothing is sent anywhere by thinslice.
+What does "state" mean exactly?
Each thinslice slice gets its own Postgres instance (cloned from yours), its own Redis instance, an isolated set of reserved ports, and environment config scoped to that worktree. Cline runs inside this environment and can't accidentally mutate your main database.
+Do I need Docker or Kubernetes?
No. thinslice uses native OS process isolation and Postgres's built-in copy capabilities. No containers, no VMs, no root access required.
+What happens when I'm done with a session?
Run slice rm <name> and thinslice tears everything down — the worktree, the Postgres clone, the Redis instance, the reserved ports. Your main environment is untouched.
+Can I run multiple Cline sessions at once?
Yes, that's the main use case. Each slice tmp call creates a fully independent environment. You can run as many parallel Cline sessions as your hardware supports, each with its own database and ports.
+Which AI providers does Cline support?
Cline supports a wide range of providers including Anthropic, OpenAI, Google Gemini, AWS Bedrock, Azure OpenAI, and many others via its configurable API settings. thinslice doesn't add any credential requirements — it just launches Cline in an isolated environment using whatever provider credentials Cline already has configured.
+Do I need git?
Yes, git worktrees are how thinslice isolates the code. You don't need GitHub or a remote — a local repo is enough. thinslice creates the worktree branch automatically.
+How does the Postgres clone work?
thinslice uses Postgres's CREATE DATABASE … TEMPLATE to snapshot your database in place. On macOS with APFS, the data files are copy-on-write so the clone is near-instant regardless of database size. See the docs for details.

thinslice is an independent open source project for giving every coding agent its own isolated slice of your stack — no Docker, no VMs, no shared databases.

It's built around the idea that agents should be first-class tenants: isolated from your working environment so you can code and ship in parallel without fear.

If thinslice saves you time, sponsorship is the best way to support continued development.
