Wiki.js
Self-hosted team wiki whose pages sync both ways with a Git repository, written in Markdown or a visual editor. 2.x is stable; 3.0 is a PostgreSQL-only beta.
Carbon
Planning, shop floor and quality in one Postgres database: an open source ERP, MES and QMS for complex assembly, contract work and high-mix, low-volume runs.
Rallly
Find a date the whole group can make with a poll people answer without an account. Self-hostable under AGPL: free for one account, a paid license beyond that.
Bracket
Run a tournament on your own server: round-robin pools that feed a knockout bracket, Swiss rounds paired from past results, drag-and-drop court scheduling.
OneURL
Linktree-style link page still running at oneurl.live, but its official GitHub repo now returns a 404 and the BSD-licensed code survives only in a copy.
Shelf.nu
Know where every piece of equipment is and who has it: phone-scanned QR labels, bookings and kits, AGPL and self-hostable if you bring your own Supabase.
listmonk
Run mailing lists and campaigns from a Go binary and PostgreSQL. Mail goes via an SMTP relay you choose (SES, Postmark, your own), which owns deliverability.
Keila
Newsletters and signup forms without Mailchimp: open source Elixir software you run behind your own SMTP relay, or that its maker hosts for you in the EU.
Databasus
Scheduled PostgreSQL, MySQL, MariaDB and MongoDB backups run from a web UI, sent to S3, SFTP or Google Drive. Physical backups and PITR need PostgreSQL 17+.
NocoDB
Run an Airtable-style database on your own server: linked tables, kanban and form views, a REST API. Fair-code since 2026, Postgres and Redis in production.
