Show HN: Free open source coding models in Slack

Cord has launched a free, open-source platform that enables developers to run parallel AI coding sessions with Claude Code or OpenCode directly within Slack. The tool allows users to spin up full development environments, write code, and open pull requests by tagging Cord in a Slack channel or assigning a Linear ticket, using their existing AI subscriptions or API keys without vendor lock-in. The platform offers persistent storage, encrypted environment variables, and a free tier with unlimited sandboxes, with enterprise plans available for self-hosting.

Create parallel Codex + Claude Code sessions with your own config and subscription . Full dev environments for testing and verification from any device. Tag Cord in a Slack channel or assign a Linear ticket — an agent spins up, writes the code, and opens a PR. No context switching. Use your existing AI subscription directly — or bring API keys. No double-paying, no vendor lock-in. Each sandbox runs its own dev server with a unique preview URL. Use it to check your changes, share it with teammates or let the agent verify its own work. Record a voice message to start an agent, review diffs on the go, and merge from anywhere. Cord supports Claude Code and OpenCode . Use Claude Code with your existing Claude subscription or API key. OpenCode works with any model provider — including a Codex subscription. You bring your own plan or keys; Cord provides the infrastructure. Yes. The enterprise plan includes self-hosting, so you can run Cord on your own infrastructure with full control over data and security. Contact us https://cal.com/prasoon/quick-chat to learn more. You only pay for compute you actually use. Sandboxes spin up in seconds and automatically suspend when idle. When you come back, they resume instantly. The free tier includes unlimited sandboxes. Every user gets persistent storage that carries over across sandbox sessions. Your .claude directory, personal dotfiles, test artifacts, and anything else that doesn't belong in the repo stays available every time you start a new sandbox. Upload them in your repository settings. They're stored encrypted in the database and automatically injected into every sandbox on startup. Yes. Docker builds are fully supported inside sandboxes. Daytona is the default sandbox provider. For teams that need more scale, Cord also supports Modal.
