Code at the
speed of light

Point any coding agent at your whole codebase, watch it work in real time, and approve every change before it ships.

Agents that work the way you think

Describe the change in plain language. The agent works across your whole project and shows you every edit as a diff.

Three ways Neumann works with you. Across your whole codebase. Across every agent. Without ever getting in the way.

Codebase-wide. Neumann understands your entire project, not just the file you're looking at. Agents reason across repositories, dependencies, configs, and tools to make changes that are globally consistent.

Open ecosystem. Neumann speaks the Agent Client Protocol, so it plugs into Claude Code, Gemini CLI, OpenCode, and whatever ships next. No lock-in, no single-model dependency.

Always on. Long-running agents, background reasoning, and parallel tasks keep humming along — the editor stays fast and never stalls while you keep working.

For the review that cannot wait until you are back at your desk.

Kick off a run, watch it land, approve the diff. All from your phone.

The chat panel jumps to the top whenever new output streams in. Can you fix the anchoring?

The one decision that cannot wait reaches you wherever you are.

Yours, and it stays that way. Your repos, your machine, your keys. Neumann fits around the setup you already have instead of asking you to move it.

  • Local-first. Your codebase stays on your machine. Indexing uploads only what it must, then deletes it.

  • Bring your own agent. Claude Code, Gemini CLI, OpenCode — anything that speaks the Agent Client Protocol. No lock-in.

  • Fully native, not a web wrapper. A true desktop app, not a browser in disguise. It opens instantly and stays fast even under heavy load.

  • Git-native review. Diffs, hunks, and staging live in the editor. Nothing lands until you say it does.

  • Parallel runs. Several agents at once, with resource usage that stays predictable while you keep working.

  • Cloud agents. Hand a task to the cloud, close the laptop, and pick the diff up when it's ready.

  • Every run, tracked. A board of what's queued, running, and waiting on you — instead of a wall of terminal tabs.

  • Automations. Hand recurring work to an agent on a schedule or a webhook, and read the result later.

  • Privacy Mode. Turn it on and Neumann keeps plaintext out of requests. An “ignore” list scopes the rest.

  • Secure by default. Strict access control and encrypted transmission for anything that leaves your machine.

  • Regional deployment. Infrastructure and data pinned to your account region — US, Singapore, or Malaysia.

  • Desktop and browser. Native builds for macOS, Windows, and Linux, plus the same workspace on the web.
