About Sparkles

Sparkles gives your whole team coding agents that work on your real codebase. Connect your GitHub repos once, and anyone on the team can start a run from the web app or by @mentioning Sparkles in Slack. Pick Claude Code, Codex, or OpenCode and describe the change in plain language. The agent works in an isolated cloud sandbox with your tools already plugged in, like Linear, Sentry, Notion and Figma. You can watch every command and file edit live and jump in mid-run. Every run ends as a GitHub pull request. CI checks stream back into Sparkles, and your reviews and branch protections still apply, so prod stays safe.
