I needed a way to create checklists from a template — think a recurring process like onboarding or a release — and share them with people who shouldn’t have to register anywhere. Most checklist tools are either too heavyweight (project management suites) or too simple (plain shared notes without state).

Checklister is built around templates and instances. A template defines the items; each run creates a new instance from it. No login, no accounts — access is controlled entirely through tokens embedded in URLs. Creating a template gives you an admin token. Creating an instance generates three separate tokens: one for checking items off, one for editing them, and one for read-only viewing. You hand out whichever token the recipient needs.

The backend is a Go server with a Chi router, storing data in SQLite. The React frontend is served from the same binary. Instances are versioned: editing items creates a new snapshot, while checking items off is tracked separately without touching the version history.

Deploy your own instance on Docker
