I build local-first tools for people working with coding agents.
Agent Island | Open source | Writing | X
I am interested in the part of agentic coding that starts after the prompt: knowing what is still running, what needs attention, what it cost, and how the workflow fits into a normal day.
An open-source status companion for Claude Code, Codex, Antigravity, Grok and Cursor on macOS and Windows. It shows live session state, calls you back with a your-turn alert, and keeps usage and cost monitoring local.
- See sessions across five coding agents as running, waiting, or needing attention.
- Get a visual and sound alert when it is your turn.
- Review local usage, cost, model mix, and weekly or monthly report cards.
- Use it without an Agent Island account or product telemetry.
- Native desktop utilities for AI-heavy workflows
- Local-first observability for long-running coding agents
- Product and distribution systems for open-source developer tools
- Clear interfaces for status, attention, usage, and cost
- How Agent Island detects Claude Code and Codex session state
- Designing a useful your-turn alert
- Where local session data begins and ends
- Installing Agent Island on macOS and Windows
Agent Island has small, scoped issues for contributors who want to work on desktop tooling, documentation, or localization:
- Refresh ROADMAP.md for the current macOS and Windows release
- Add Japanese UI localization
- Add a guard for retired public claims
- Browse all good first issues
