Best for
  • ML engineers fine-tuning open models
  • Research teams needing reproducibility
  • Practitioners running multi-GPU training
  • Privacy-conscious developers
  • MCP / Claude Code / Codex users
  • Self-hosting enthusiasts
Pros
  • Free and open source under MIT/Apache
  • Single YAML config makes runs reproducible
  • Supports LoRA, QLoRA, and full fine-tuning
  • Multi-GPU training with FSDP and DeepSpeed
  • Very active development and new model support
  • Fully local-first — no data leaves your machine, no external LLM calls
  • Works across pi, Claude Code, Codex, and any MCP client via one service
  • Hybrid BM25 + vector search finds both exact tokens and paraphrases
  • SQLite source of truth with rebuildable indexes (resilient to corruption)
  • Encrypted AES-256-GCM vault for secrets, kept separate from memory
Cons
  • Requires ML and infrastructure expertise
  • No managed UI or hosted service in the core project
  • You supply and pay for your own GPUs
  • Debugging distributed runs can be complex
  • Not aimed at non-technical users
  • Very early-stage project with minimal adoption so far
  • Self-hosted only — no managed or cloud option
  • Prebuilt install is Linux-first (Windows/WSL via scripts or a source build)
  • Requires manual setup to wire into each agent/harness
  • No team collaboration or shared-server hosting out of the box
