Squiid vs Composio
Composio connects agents to apps your users already have: hosted OAuth and a large tool catalogue, so a model can act in Gmail, Slack or Notion. Squiid buys and bills the infrastructure underneath.
Short answer. If your agent needs to read a user calendar, file a GitHub issue or post to their Slack, Composio is built for that and Squiid has no equivalent. If your app needs a Postgres database, a host and an email sender of its own, that is Squiid.
The one-line difference. Composio connects an agent to accounts your users own. Squiid provisions and pays for the accounts your application owns.
Side by side
| Composio | Squiid | |
|---|---|---|
| What it covers | Tools for agents. Hosted authentication plus a catalogue of third-party app integrations exposed as callable tools or MCP servers. | The services your app runs on: models, databases, hosting, email, SMS, storage, auth, search, observability and payments, provisioned and billed. |
| Non-AI services | The connected apps are ordinary SaaS products, but the purpose is agent tool calling. No database, host or email sender for your app. | Yes. Postgres, object storage, email, phone numbers, error tracking. |
| Provisioning of accounts | It runs the OAuth dance for accounts your users already have. It does not buy infrastructure for you. | Yes. Squiid opens the account and holds the credential. |
| Key custody and rotation | Yes, for user tokens. It stores and refreshes end-user OAuth credentials, a different kind of custody. | Squiid holds and rotates the provider keys. Your project carries one gateway key, worthless outside it. |
| Billing model | Its own platform plans, as of their public docs. Connected SaaS accounts are billed to whoever owns them, usually your user. | Prepaid credits at par: $1 of credit is $1 at the provider. Subscriptions pass through at list price. |
| Fee | No fee on provider usage, because the connected accounts are not being resold. | Free $0/mo + 15% at top-up. Solo $19.97/mo from 8%, falling to 3.5% with spend. Team from $29.97/seat, one point lower. Custom 3% or less. |
| One invoice PDF | One invoice for the platform. Your infrastructure vendors still invoice you separately. | Yes. One monthly PDF: credits, plan, subscriptions. |
| Spend caps and pause-on-zero | Permission and rate controls over tool calls. No prepaid balance to run out of. | Yes. Alerts at 75, 90 and 100%, capped auto top-up, pause at zero. |
| Works with coding agents | Yes. That is the entire design. Function calling and MCP for agents. | Yes. One variable and one base URL convention for every service. |
| Self-host option | Open-source components exist, with the hosted platform as the main path. | No. Hosted only. Leaving is a transfer where the provider supports one, a documented export otherwise. See handover. |
| Best for | Agents acting inside a user SaaS account on their behalf. | Projects that need infrastructure bought, credentialed and billed, rather than end-user SaaS accounts connected. |
When to pick Composio instead
Pick Composio when the feature is the integration. If your agent triages the user inbox, updates their CRM or opens pull requests, you need per-user OAuth, token refresh, scopes and a tool schema. Building that for five apps is weeks of work you then maintain forever.
Pick it when you need breadth quickly. A catalogue of ready-made tools is a real shortcut, and tracking API changes across hundreds of vendors is somebody else full-time job.
Pick it when MCP is how your agent sees the world. Exposing tools through a protocol the agent already speaks removes a translation layer.
When Squiid is the better fit
Squiid is the better fit for the other half of the same product. Your agent still has to run somewhere, store something, send an email and authenticate a user: five signups and five invoices before a single tool call.
It is also the better fit for what the agent costs you. Tool calls are cheap; the model tokens, the database and the email volume behind them are not. A prepaid balance with a pause at zero covers the part of the bill that grows.
And it is the better fit for custody on infrastructure. Composio holds your users tokens, which is right. Nobody holds your Postgres URL, Resend key and Stripe secret unless something upstream does.
Use both
Together they are close to a complete agent product. Composio handles the integrations your users connect; Squiid handles the services you buy. The agent ends up with one tool provider and one gateway key instead of a sprawling environment file.
Questions people ask
Does Squiid connect my users Gmail or Slack accounts?
Not the way Composio does. Squiid has connect integrations for accounts you own, such as Stripe, GitHub, Slack and Notion. Per-end-user OAuth at scale, with token refresh and tool schemas, is a different product.
Could I use Composio to get a database?
No. It connects to applications, not infrastructure. There is no Postgres project, deployment target or phone number at the end of a tool call.
Which one holds more dangerous credentials?
Composio, arguably, because end-user OAuth tokens grant access to somebody else data. Which is why a product built for it beats storing refresh tokens in your own database.
Do the two ever conflict?
No. They sit at different layers and never touch the same credential. Your agent reads two environment variables.
What does Squiid do about MCP?
It is on the roadmap as the preferred way for agents to get short-lived credentials. Today the interface is one API key and a base URL convention, which every agent understands.
Tools for the user.
Infrastructure for the app.
The services your agent runs on, at provider prices, on one key.
