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

Retell AI

What works

  • Sub-second latency for natural-feeling conversation
  • Built-in telephony — bring a phone number, plug in
  • Function-calling support for CRM updates, calendar booking, etc.
  • Predictable per-minute pricing scales linearly with volume
  • Production-grade — used by hundreds of B2B teams in 2026

What doesn't

  • Per-minute pricing adds up at very high volume
  • Lock-in to Retell's voice stack
  • Less flexibility than building on raw infrastructure
  • Voice quality is good but not the best on the market
  • Customer support response times vary
