Composio vs Zapier

Two fact sheets from our own research, side by side — pricing, platforms, API access and status re-checked by us rather than quoted from the vendors.

The short answer

Cheaper paid plan: Zapier — $19.99/mo vs $29/mo for Composio
Free plan: Both have one
Public API: Both have one
Best fit: Composio: Developers building AI agents that need to take real actions in external apps, not just chat · Zapier: Ops and marketing teams wiring SaaS tools together without engineering time
Platforms: Composio: Web · Zapier: Web, Chrome extension, Slack app

From our own records as of each tool's last check. Anything we have not confirmed is left out rather than guessed. How we verify

ComposioGives AI agents authenticated, rate-limited access to over 1,000 external tools and apps through one API.

ZapierConnects thousands of apps and runs agent steps

What our research says

Composio

Composio solves a specific, real developer problem — letting an AI agent actually call Gmail, GitHub, Slack, and a thousand-plus other tools with proper auth handling — rather than building that plumbing per project. It's usage-priced per tool call past the free tier, and it's a funded, San Francisco-based company (Series A led by Lightspeed) rather than a thin indie site.

Pros

Over 1,000 pre-built integrations with handled authentication, rather than building each one manually
Free tier includes 100,000 tool calls and unlimited connections a month before any charge
Works with MCP clients (Claude Code, Cursor) as well as direct SDK integration
Backed by a real Series A ($25M, led by Lightspeed) rather than an unfunded side project

Cons

Pay-as-you-go overage pricing per tool call can get harder to predict at high volume
Premium tools like browser automation cost meaningfully more than standard tool calls (roughly $0.70/task)

Zapier

Zapier is still the default when the job is 'connect these two SaaS tools and stop thinking about it': the app catalogue is the moat, and Copilot cuts setup time further for people who would never write a webhook. The cost model punishes volume — tasks are counted per step, overage on monthly plans is 2.5× — so once an automation runs thousands of times a day, Make or self-hosted n8n gets cheaper fast, and the AI Agents are a separately billed add-on rather than part of the plan.

Pros

More than 9,000 app integrations, the widest catalogue in the category
Copilot builds a multi-step Zap from a description, so setup needs no documentation reading
Free plan runs real two-step automations, not a time-limited trial
Published prices for every tier short of Enterprise, including the overage multipliers

Cons

Tasks are counted per step, so a five-step Zap burns five tasks per run
Overage costs 2.5× the base rate on monthly plans
Agents and Chatbots are add-ons with their own bills
Multi-step Zaps need a paid plan

Which one fits

Choose Composio if you need

Developers building AI agents that need to take real actions in external apps, not just chat
Teams already using MCP-compatible tools like Claude Code or Cursor who want a shared integration layer

Choose Zapier if you need

Ops and marketing teams wiring SaaS tools together without engineering time
Low-volume automations where the app catalogue matters more than cost per run
Teams that want AI steps and agents inside workflows they already run
