Kilo Code

What works

  • VS Code, JetBrains, and CLI — the broadest IDE coverage of any coding agent on this list
  • 500+ models via Kilo Gateway — not locked to Anthropic or OpenAI
  • Cloud agents run 24/7 without your laptop open
  • Apache-2.0 open source — auditable and self-hostable
  • Slack, Discord, and Telegram integrations for async agent workflows
  • Free tier with no credit card required

What doesn't

  • Newer than Cursor or Cline — smaller community, less battle-tested documentation
  • 500+ model support adds decision overhead — more choices don't always mean better outcomes
  • Cloud agent feature is newer and less proven at scale than established CI/CD-based approaches
  • JetBrains support, while a key differentiator, lags VS Code in feature parity

Stack AI

What works

  • Best-in-class document ingestion and RAG pipeline
  • Strong enterprise data connectors (Notion, Confluence, Google Drive)
  • SOC 2 compliant
  • Good UI for non-technical configuration

What doesn't

  • Expensive at team scale ($199+/month)
  • Limited flexibility for multi-step process automation
  • Weaker for external-facing or trigger-based workflows

Which to pick

We'd default to Kilo Code (4.0/5 vs 3.5/5) for most builders. Pick Stack AI if you fit its best-for case specifically: ops teams who want ai agents over their internal documents — sops, contracts, product specs, notion wikis.

Honest middle: most serious operators end up using more than one tool. If you're early in your AI agent journey, our five-question picker recommends a starting platform from your specific situation.
