Tainer 2.0: now open source

Tainer is now open source under the AGPL-3.0. 2.0 also brings a load balancer that starts in dry run and plans whole-cluster moves, Tainy on your own model, live updates, API tokens and 35 security fixes.

  • Source code on GitHub under the GNU Affero General Public License v3.0, with CI, CodeQL and OpenSSF Scorecard

  • Tainy (formerly Copilot) runs on any OpenAI-compatible endpoint, with per-group tool policy, operator notes, usage and cost tracking
  • Tainy can pull a Docker image and start it as a container, or download an ISO and create a VM from it
  • Real-time updates on the dashboard, deployments list and deployment pages
  • Scoped API tokens for scripts, Terraform and CI
  • Per-deployment firewall panel, encrypted backups of Tainer's own state and admin 2FA reset
  • 35 security fixes and hardening changes. Set AUTH_SECRET before upgrading
