Composio

What it is for

Composio is an agent tool layer: one session exposes 1,000+ apps (Gmail, Slack, GitHub, Notion, …) so an agent can discover a tool, connect an account, and execute it. Use it when the job is give the agent the app, not when you need a visual Zap canvas.

The SDKs are open source (ComposioHQ/composio). Hosted Hobby is $0 (100,000 tool calls / month). Pro is $29/month.

What makes it unique: the cover is Composio’s official plan grid — Hobby $0, Pro $29/mo, tool-call and trigger caps on the same cards.

Key features

• Toolkits — 1,000+ apps as agent-ready actions (read a PR, send Gmail, file a ticket) (Toolkits).
• Runtime tool discovery — a session exposes a small set of meta-tools; app schemas load when the agent needs them (Quickstart).
• Hosted auth — OAuth / API-key connect links so the user authorizes Gmail (or GitHub) without you building the consent screen (Getting Started: TypeScript).
• Triggers — webhook / event subscriptions that wake an agent (new PR, new email) on the same meter as tool calls (Pricing).
• Framework SDKs — drop the same toolkits into LangChain, CrewAI, OpenAI Agents, or Vercel AI SDK (Quickstart).
• Search + sandbox tools — Exa, E2B, and similar actions sit next to Gmail / Slack in the toolkit catalog (Premium tools).

Who it's for

Best fit: agent builders who will connect real user accounts and stay under 100k tool calls until Pro.

Poor fit: ops teams who want a drag-and-drop Zap with no agent loop (Zapier).

Pricing

Verified 2026-10-22 (Asia/Shanghai) from composio.dev/pricing and updated-pricing. Re-check overage.

• Hobby — $0. 100,000 tool calls / month. 50,000 trigger events / month. Unlimited connected accounts. 3 team members. No card. Usage pauses at the cap (you are not surprised-billed).
• Pro — $29/month. Everything in Hobby plus a $29 monthly usage credit (does not roll). Unlimited members. Spend controls and add-ons.
• Enterprise — custom. Volume, SSO / SCIM / KMS, MSA / DPA / SLA.

Overage (Pro) — tool call $0.0003; trigger event $0.003. Composio-managed shared apps are a tighter slice of the free cap (up to 20k of the 100k tool calls). Premium tools bill provider cost + 5%.

Limitations / costs

• Hobby stops at 100k calls. A chatty agent loop is not “free forever.”
• $29 credit expires monthly and does not roll.
• Premium tools are a second bill (Exa, E2B, SerpAPI, …).
• Not a Zap editor. You still write the agent.

Alternatives

• n8n — visual workflows if the agent should not own the tool call.
• Zapier — hosted Zap if you will not run an agent loop.
• LangChain — write the tools yourself if you do not want a toolkit catalog.
