Paperclip

What works

  • The only open-source multi-agent orchestration platform
  • Works with any agent runtime — fully vendor-agnostic
  • Hard budget limits per agent prevent runaway API costs
  • Immutable audit trail for every agent decision
  • Active development — latest release April 2026

What doesn't

  • Not a starting point — assumes you have agents to orchestrate
  • Self-hosting requires PostgreSQL and Node.js infrastructure
  • Smaller community than OpenClaw or Hermes

Vertex AI Agent Builder

What works

  • Gemini's 1M+ token context window — the largest on the market
  • Native integration with BigQuery, Cloud Storage, Google Workspace
  • Grounding with Google Search built in (real-time web data)
  • Google Cloud security, compliance, and IAM
  • Free tier credits for new accounts make evaluation easy

What doesn't

  • Gemini-only — no Claude, GPT, or Llama support
  • Only makes sense if you're already on Google Cloud
  • Slower iteration than Anthropic or OpenAI direct
  • Documentation is dense and assumes Google Cloud familiarity
  • Enterprise contract overhead at scale
