Run a fleet ofClaude Code, Aider, and moreIn parallel. Fully isolated. Token efficient.
The open-source, token-efficient way to run Claude Code, Aider, and more AI coding agents in parallel — up to 64% fewer tokens, each agent on its own git branch: zero merge conflicts, live status, built-in diff and PR.
One knowledge graph. Every agent you already use, in parallel
HOW IT WORKS
Open Tempest. Start a session in 3 steps.
Download Tempest
Install the desktop app in seconds on Windows, macOS, or Linux. No account, no subscription, no sign-up required.
Open your repo
Point Tempest at any git repository. Sessions get their own isolated worktrees automatically — no manual branching.
Run agents in parallel
Pick your tool — Claude Code, Aider, OpenCode, or any other. Launch multiple sessions and watch them work simultaneously.
WHY TEMPEST
More windows don't give you more isolation.
They give you more chaos.
Shared knowledge base. Every agent on its own branch — nothing steps on anything else. Run five in parallel without confusion.
Isolated git worktrees
Each session runs on its own branch. Agents never touch each other's files, so no merge conflicts mid-run and no stepping on uncommitted changes.
Token intelligence
A local code-knowledge graph lives on your machine and is shared across every session. Agents pull from it instead of scanning files on their own — up to 64% less context, up to 58% fewer tool calls.
Session continuity
Close a tab, reopen it, and the agent resumes exactly where it left off with full history intact. Nothing is lost.
CORE FEATURES
Everything you need to run parallel AI agents.
Nothing you don't.
One window
Claude Code, Aider, OpenCode, Copilot CLI, Cline, Goose — every agent running in parallel, one window.
Worktree isolation
Every session gets its own git worktree and branch. Agents never touch each other's files.
Full history
Close a tab and reopen it later. Each agent resumes exactly where it left off.
Live status
See the instant each agent finishes a turn. No tab-watching, no babysitting.
Diff, commit, PR
Review every change in a live diff viewer. Stage, commit, push, and open a PR without leaving Tempest.
Live preview
Watch your dev server update in real time as agents change code.
Real terminal
ANSI color, in-session search, clickable links — a full terminal in every session.
Token Intelligence
A shared code-knowledge graph cuts context tokens up to 64% and tool calls up to 58%. Coming soon.
Database branches
An isolated Postgres instance per agent, so parallel runs never corrupt each other's data. Coming soon.
Zero conflicts
Even a rogue agent can't reach your main branch. Blast radius: zero.
Native, not Electron
Tauri 2 native performance on Windows, macOS, and Linux.
And more
New features ship every week. Tempest is just getting started.
CORE CAPABILITIES
Built to handle the hard parts.
So you can focus on shipping.
PARALLEL SESSIONS
Five agents running. Zero collisions.
Each session runs in its own isolated git worktree. Agents never touch each other's files — no merge conflicts mid-run, no stepping on uncommitted changes. You switch tools the same way you switch tabs.
Each agent on its own branch, automatically
No stash juggling, no detective work
Switch between Claude Code, Aider, OpenCode and more
BUILT-IN DIFF & PUSH
Review what each agent changed. Ship it without leaving Tempest.
A stream diff viewer shows exactly what each agent touched. Stage, commit, push, and open a PR — all without switching to another tool.
Stream diff viewer per session
Stage, commit, and push from inside the app
Open a PR without leaving Tempest
LIVE PREVIEW
Watch changes land in real time. No alt-tab, no second monitor.
Your local dev server updates live as agents make changes. See the result without switching context — right inside Tempest.

No external browser tab required
WHO IT'S FOR
Built for developers who ship in parallel.
And want to ship faster.
Solo builders
Run five agents in parallel and build five features at once. Ship a week of work in a day, and keep every thread straight.
Freelancers
Client A, B, and C — each agent on its own branch and worktree. Switch context without the chaos or the merge conflicts.
Open source contributors
Try three approaches to the same issue at once. Drop the ones that fail, merge the one that works. No stash juggling.
Teams
Every teammate's agent runs isolated in its own worktree, so automated sessions never cause merge conflicts. Review diffs, push, and open PRs inside Tempest.
