What you can do with OpenChamber.

Session Goals

Set a finish line. The agent keeps working toward it, turn after turn — even with the app closed.

Multi-run and Fusion

Run one task across up to five models. Keep the best result, or fuse the strongest parts.

Changes Walkthrough

A large diff, grouped into ordered steps that explain how the change fits together.

Preview

Point at an element in your running app and send the agent everything behind it.

From issue to pull request

Start from a GitHub issue or PR, send failed checks back, and merge without leaving.

Scheduled work

Run a prompt on a cron schedule. Pair it with Session Goals to aim at an outcome.

Loved by Developers<br>Early users keep describing the same thing: less tab-hopping, less guesswork, more steady forward motion.

After years of switching between IDEs and TUIs, I found the sweet spot for everything I need: Openchamber.

"I just want to say the app itself is phenomenal. The level of polish is just unreal. I saw OpenChamber back when it was a small project, I think maybe a couple months ago, and now it is unrecognizable. Truly amazing work. The latest release with its streaming feature is everything I could have possibly asked for and more. It is gorgeous and smooth."

"Opencode + OhMyOpencode + Openchamber. This is some cooked stack. VSCode looks like legacy notepad++ now."

Daniel Duma<br>@drdanponders

"Stop using Openclaw for coding! Use OpenCode and OpenChamber instead!"

Abundance Mentality<br>@1un4rPunk

"Seriously, I've spent almost the whole week trying to find a tool that made sense to orchestrate agents and, as a dev (actually, a devops), openchamber is the only one that felt natural and logical."

Privacy & Data<br>Nothing about your work is collected or sent anywhere. Your code and session content stay on your machine, and remote access can be protected when the workspace leaves localhost.

Code and sessions stay with you<br>Project names, paths, prompts, code, diffs, and session content are not collected by OpenChamber.

Remote access is protected<br>Browser access can be gated with a UI password, and tunnel links can be rotated or revoked when they should no longer work.

Private Relay, no open ports<br>Pair a device with a one-time QR code and connect through Private Relay without opening ports or exposing a public server. The connection is end-to-end encrypted and can be revoked at any time.

Privacy is inspectable<br>OpenChamber is open source, so the privacy model is visible in the code instead of hidden behind policy language.
