Now in early access

Your dev environment wasn't
built for this.

You run agents across multiple projects all day. But your terminal, your browser, and your ports weren't designed for it. Polystro gives every project its own isolated environment — so agents work in parallel without stepping on each other.

How it works

How a session looks.

Step 1

Open your projects

Each gets its own ports, browser identity, and terminals — fully isolated from every other project.

Step 2

Run agents in parallel

Each agent gets its own git worktree. Claude on auth, Codex on tests — same repo or different repos, no conflicts.

Step 3

Review and merge

The merge center shows everything that changed. Stage hunks, open a PR, ship it.

One workspace.
Everything isolated.

01 — Automatic Port Rewriting

Port collisions fix themselves

When a requested port is already taken, Polystro automatically rewrites it to an open port and updates routing so your frontend and backend can still talk to each other without manual fixes.

Routing OverviewAuto remap active

Port `3000` already in use. Rewriting routes to open ports.

02 — Per-Project Isolation

No more logging in to the wrong account

Each project runs on its own .local domain with its own ports and browser identity. Cookies and sessions are isolated. Switch between my-startup:3000 and client-app:3001 without anything bleeding across.

03 — Parallel Execution

Every agent gets its own worktree

Claude on auth. Codex on tests. Gemini on docs — all at the same time, each on an isolated git worktree. No file locks, no merge hell, no stepping on each other’s code.

04 — Merge Center

Merge everything agents built

Four agents, four branches, inevitably some overlap. The merge center shows exactly what changed, lets you stage hunks, and open a PR — without leaving Polystro.

Frequently asked questions

What does the free trial include?

7 days of full access to everything. Credit card required at sign-up. Cancel before renewal to avoid being charged.

Do I need API keys to use AI agents?

No. Polystro integrates with your existing Claude, Codex, Gemini, or OpenCode subscriptions directly. You use your own accounts — no extra API keys or costs.

How does parallel agent execution work?

Polystro abstracts git worktrees so each agent works on its own isolated branch. You can run multiple agents on the same repo or across different repos simultaneously. When they're done, the merge center helps you resolve any conflicts.

Who is Polystro built for?

Developers doing AI-driven development across multiple projects. If you’re running Claude, Codex, or Gemini across repos and dealing with port collisions, session bleed, or worktree chaos — Polystro isolates everything so your agents can run in parallel without conflicts.

Why this pricing?

We’re offering launch pricing while we’re in beta. Lock in $9/month (yearly) or $12/month now — prices will increase after launch. Polystro replaces a stack of manual workarounds and pays for itself in the first session.

What platforms are supported?

macOS (Apple Silicon & Intel), Windows 10+, and Linux (.deb & .AppImage).

Your agents are ready. Your environment isn't.
