Composio vs Nango: Pricing, Features
Short answer: Composio is the quicker start if you want an agent working across many apps, and its free plan covers 100,000 tool calls a month. Nango suits teams that own the integration code, run data syncs or self-host, and its free plan covers 10 connections. Both support MCP.
We review every app we compare by using it and by reading what its docs and its users say. The specifics below come from each vendor's docs, quickstart, pricing page and public reports such as GitHub issues, forum threads and Hacker News, with the source type named each time. Where evidence is thin, we say so. Vendor claims are attributed.
At a glance
Composio vs Nango features
| Feature | ||
|---|---|---|
| Approach | Hosted tool catalog with managed auth, used through sessions per user | Code-first platform for auth, tools, syncs and webhooks; integration logic written as TypeScript functions you generate with AI, then edit and version (per Nango) |
| Catalog size | 1,500+ apps on its homepage (per Composio) | 1,000+ APIs on its homepage, and 10,000+ tools or templates (its homepage uses both words for the figure) (per Nango) |
| Authentication | Composio-managed auth by default, connected accounts kept per user ID, a Connect Link when a task needs an account | OAuth, API keys, token refresh, scopes and credential storage |
| MCP | Hosted MCP endpoint; its homepage describes pasting one MCP URL into a client such as Cursor | MCP server; an agent session returns an MCP URL and a session token |
| Triggers and webhooks | Trigger events, billed separately from tool calls | Webhooks and triggers that react to external events |
| Data sync | Not listed on the pages we read | Scheduled, resumable syncs with checkpoints; syncs are not part of free self-hosting |
| Developer interface | Python and TypeScript SDKs, a REST API and a CLI | TypeScript functions; setup calls shown with curl; agent example uses the Vercel AI SDK |
| Open source | SDK repository is MIT licensed (30.8k GitHub stars) | Elastic License, which is source-available; Nango's README and homepage call it open source (13.0k GitHub stars) |
| Self-hosting | Not listed on its pricing page or homepage | Free self-hosting is limited to API auth and proxy per its self-hosting docs; full self-hosting and bring-your-own-cloud need Enterprise |
| Security | SOC 2 Type II (per Composio); SSO/SCIM and customer-managed keys on Enterprise only | SOC 2 Type II and HIPAA with a BAA (per Nango); RBAC, audit trail and encryption listed on its homepage |
| Support | Portal on Hobby, portal and email on Pro, dedicated support and custom SLAs on Enterprise | In-app chat; private Slack on the Growth add-on and Enterprise |
Composio vs Nango pricing
Composio bills mainly on tool calls and trigger events. Nango bills on connections, compute hours and data transfer, so the plans do not compare directly.
| Plan | ||
|---|---|---|
| Free | Hobby, $0. 100,000 tool calls and 50,000 trigger events a month, 3 team members, unlimited connected accounts. Usage pauses at the cap. | Free, $0. 10 connections, 10 compute hours and 10 GB data transfer a month. Hard-capped, resets monthly. |
| Paid | Pro, $29 a month. Includes a $29 monthly usage credit, then $0.0003 per tool call and $0.003 per trigger event. | Pay-as-you-go, $50 a month. Includes $50 of credits, then $0.29 per connection, $0.72 per compute hour, $0.50 per GB. |
| Support add-on | Email on Pro | Growth add-on, $450 a month: private Slack and 5 days requested integration delivery time |
| Enterprise | Custom. SSO/SCIM, customer-managed keys, dedicated support and custom SLAs. | Custom. Self-hosting, bring your own cloud, MSA, SLA and commitment discounts. |

What users and the docs say
We read each quickstart and pricing page, scanned each vendor's public GitHub issues and looked for forum threads and reviews. Independent hands-on write-ups comparing these two are scarce, so evidence on day-to-day use is thin, and each point below names its source type.
Composio
From the quickstart. You install the packages for your framework, add API keys to a .env file, create a session for a user ID and pass the session's tools to your agent. When a task needs an account, the agent shares a Connect Link, the user approves it and the agent carries on. The same page carries a prompt for coding agents and rules for AI code generators beside the human walkthrough, so a person reading it has to skip parts.
From GitHub issues. Recent open reports on the Composio repository lean towards auth and connected accounts: a Trello tool returning an invalid-token error on valid connections (#4962), a connect error page that hides the provider's error detail (#5038) and Composio-managed Outlook auth missing the scopes its To Do tools need (#5033). These are individual reports, not a measure of how often they happen.
From the pricing page and a forum thread. Hobby usage pauses at the cap instead of billing overage, so a busy test week can stop work. In an older Cursor forum thread on MCP servers, one commenter called Composio a much better experience for plugging in MCP servers, while others worried about a remote server dropping out and about Composio controlling users' keys. That thread predates the current session-based product.
Nango
From the quickstart. Nango's current quickstart is built around agent sessions. You copy the environment API key into a backend env file, enable the APIs your agent needs by provider slug, and have your backend call POST /sessions with a stable user ID. The response holds an MCP URL and a session token that you pass to the agent as a remote MCP server. The first time a user needs an account, the agent replies with a connect link, and the docs name the Logs tab as the place that shows every tool call, provider request and response.
From GitHub issues and the docs. Open reports on the Nango repository cluster around self-hosting: a connect link from a self-hosted instance sending the Connect UI to Nango's cloud host (#7945), a CI environment variable switching the dashboard into a test-auth mode (#7955) and a request to clarify the self-hosted feature set (#5536). Nango's docs say free self-hosting covers API auth and proxy only.
From Hacker News. In a launch thread, several commenters objected that the Elastic License is not OSI-approved open source, and the title was changed to say source-available. One commenter said Nango cut their time to integrate, and another reported a year of stable use for OAuth flows. That thread predates the product's current focus on agents and code-owned functions.
Which to choose
If you want an agent working across many apps quickly, Composio is the easier start. If you need data synced on a schedule, want to read and change the code, or have to host it yourself, Nango fits better. Both have free plans, so trying each on a real use case costs little.
Where viaSocket fits
viaSocket also sells an integration layer; it is not part of this comparison. In short, it is an integration layer for SaaS products and AI agents with 2,300+ integrations. Your user connects through one OAuth popup, viaSocket stores and refreshes the tokens, keeps each user's connections separate, and handles monitoring, webhooks, polling and retries. Its free plan lists 100K tasks a month and unlimited connected accounts.
It suits teams that want ready-made connections and managed auth in one place. If you need to self-host or write every sync in code, Nango remains the closer fit.

Composio is a hosted catalog of ready-made app tools with managed auth. Nango is a code-first platform that covers auth, tools, data syncs and webhooks, and expects you to own the integration code.
Do Composio and Nango both have a free plan?
Yes. Composio's Hobby plan includes 100,000 tool calls and 50,000 trigger events a month. Nango's free plan includes 10 connections, 10 compute hours and 10 GB of data transfer a month.
How much do Composio and Nango cost?
Composio Pro is $29 a month with a $29 usage credit, then $0.0003 per tool call. Nango's pay-as-you-go plan is $50 a month with $50 of credits, then $0.29 per connection, $0.72 per compute hour and $0.50 per GB. Both have custom Enterprise plans.
Do both support MCP?
Yes. Composio exposes sessions through a hosted MCP endpoint, and Nango offers an MCP server whose agent sessions return an MCP URL.
Is Nango open source?
Nango's homepage and README call it open source, and its GitHub page names the Elastic License, which is source-available. Composio's SDK repository is MIT licensed.
