Composio
Tool and app connections with managed auth for AI agents
Mastra
TypeScript framework for building and running AI agents
Which one is for you
Pick Composio if
- Fits if you build agents and want one layer for app connections and OAuth
- Works for a small team trying tool calls on a free plan
Look elsewhere if
- Watch out: the pricing page covers two products, per seat for For You and per workspace for the platform
- Tight if you are on For You Free, where Firewall, SSO and zero data retention are not included
- Pricey if you go over: $0.005 a tool call on For You, $0.0003 on Pro
- Watch out: Platform Hobby stops at its limits, and managed apps are capped at 20,000 calls there
Pick Mastra if
- Fits if you write TypeScript and want to build your own agents
- Works for teams that want to deploy agents on Vercel or Cloudflare
Look elsewhere if
- Not for you if you want no-code, since building an agent means writing TypeScript
- Pricey if you grow, as past the allowance egress is $0.10 a GB and events $10 per 100K
- Watch out: RBAC, SSO and audit logs are Enterprise only, and the SOC 2 report starts at Team at $250
- Watch out: some repository folders (ee/) sit under a separate enterprise licence

Worth knowing
Composio
- The pricing page covers two products; the For You plans are priced per seat and the platform plans per workspace, so check which one fits.
- On the free For You plan, Firewall, SSO and zero data retention are not included; they start at Standard.
- Extra tool calls cost $0.005 each on For You, and $0.0003 each on the platform's Pro plan after the included amount, paid from credits.
- Platform Hobby stops at its included limits rather than billing overages, and Composio-managed apps are capped at 20,000 calls there.
Mastra
- It is a code framework, so building an agent means writing TypeScript; there is no no-code builder.
- Cloud usage past each plan's allowance is billed separately, for example $0.10 per GB of egress and $10 per 100K observability events.
- RBAC, SSO and audit logs are Enterprise only, and the SOC 2 report starts at the Team plan.
- Some directories in the repository are under a separate enterprise license (ee/), so not every file carries the main open-source terms.
Key features
Composio
- 1,700+ app toolkits
- The catalog covers apps such as Gmail, Slack, Notion, Salesforce, HubSpot, GitHub and Linear, with authentication handled by Composio.
- Managed OAuth
- Consent, token storage, refresh and scopes are handled for every connected account, with the option to pass your own tokens instead.
- Triggers
- Events from connected apps are delivered to a webhook, so an agent can start from something that happened in another app.
- MCP gateway and custom servers
- One managed MCP endpoint exposes the connected tools, and servers from other providers or your own team can be added beside them.
- Firewall
- Plain-English policies check tool requests and results, and the vendor says it blocks instructions hidden in tool output and catches secrets.
- Instant tools
- Audio, video, image, search and enrichment tools run on Composio's own provider accounts, billed from credits rather than separate sign-ups.
Mastra
- Agents
- Typed agents are defined in code with instructions, a model, tools and runtime behavior in one place.
- Workflows
- Typed steps can be chained with retries and branches into workflows that a team can inspect.
- Memory
- Agents can keep durable context through thread-aware storage, semantic recall and an observational memory option.
- Observability and evals
- Traces, metrics and logs sit alongside evaluation tools such as scorers, datasets and experiments.
- MCP servers
- Agents, tools and other resources can be exposed as Model Context Protocol servers that any MCP-capable system can call.
- Deploy anywhere
- A Mastra app runs on any Node.js host or as a standalone server, with optional deployers for Vercel, Netlify and Cloudflare, or on Mastra Cloud.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
