Arc0 vs Composio.
Considering Arc0 as a Composio alternative? A like-for-like read on how each is priced, whose name your users see, who holds the tokens and what gets stored, including where Composio is still the better choice.
Arc0 and Composio, line by line.
| Item | ARC0 | COMPOSIO |
|---|---|---|
| Pricing unit | Active connected users; calls unlimited within fair use | Tool calls, plus per-call surcharges for some features |
| Free tier | Unlimited development-mode users; 100 active users in production | 100,000 tool calls a month |
| Your users’ consent screen | Your logo on every plan; your domain and OAuth apps on paid plans | Composio’s name unless you register your own OAuth apps; full connect-page theming $0.30 per connection |
| Token export | Any time, by API, on every plan | Tokens aren’t returned by the API |
| Request and response data | Not stored by default | Kept up to a year by default; can be turned off |
| Audit log | On every plan: 30 days on Build, 90 days on Launch | Logs: 7 days on Free, 30 days on Scale |
| Catalog | 1,500+ apps, plus official MCP servers behind Arc0 auth | 1,500+ apps |
Where Composio is the better choice.
Composio’s own OAuth apps let you connect many providers without registering an app of your own. The trade-off is that the consent screen names Composio.
100,000 tool calls a month for free is a lot of room to prototype, and there is no card to start.
Scale starts at $29 a month with a low per-call rate. For light, predictable call volume, per-call billing can cost less than per-user.
What Arc0 does differently.
Arc0 Connect carries your logo on every plan. On paid plans it runs on your own domain, and we help you set up your own OAuth apps so providers name you too.
Export your users’ tokens whenever you want. With your own OAuth apps, exported tokens keep working, so leaving never means a mass reconnect.
Retries, searches and code-execution loops don’t add to your bill. Failed calls and development mode are free.
Request and response payloads aren’t kept unless you turn on retention for debugging.
Scopes, approvals and the audit log are on every Arc0 plan, including free.
Arc0 is the plug between agents and apps, for products that ship agents. That is the whole company.
What moving from Composio looks like.
Composio’s pricing page says plans for earlier customers move to its current pricing on 31 December 2026. If you are reviewing your setup before then, this is how a move to Arc0 works. Launch teams agree their Arc0 price up front and keep it for 12 months.
Connections
Composio doesn’t return tokens through its API, so existing connections can’t be copied across. Your users reconnect once, to your own branded connect flow, and we help you stage it: new users on Arc0 first, then existing users prompted in-product when their agent next needs an app.
Your agent
Point your agent at Arc0 MCP, or swap the SDK calls. Actions are named by app and verb, like gmail.send_email, and each carries a read, write or destructive scope for your policies. See the concepts for how the pieces fit.
Questions, answered.
Is Arc0 a good Composio alternative?
If you ship an agent inside your own product and care about your brand on the consent screen, owning your users’ tokens and predictable pricing, yes. If you want provider consent screens handled by a vendor’s own OAuth apps, or low, predictable call volume billed per call, Composio may suit you better.
Is Arc0 cheaper than Composio?
It depends on how your agent behaves. Composio charges per tool call; Arc0 charges per active connected user with calls unlimited within fair use. Agents that make many calls per user tend to cost less on Arc0. Tell us your usage and we will give you a number, locked for 12 months.
Will my users have to reconnect?
Yes, once, because Composio doesn’t export tokens. We help you stage it so most users reconnect inside your product the next time their agent needs an app.
Does Arc0 work with the same agent frameworks?
Arc0 MCP is a standard remote MCP endpoint, so it works with any client or framework that supports remote MCP, including the OpenAI Agents SDK, Claude Agent SDK, Vercel AI SDK, Mastra and LangGraph.
