The strongest Composio alternatives in 2026 are Arcade.dev, Pipedream Connect, Merge Agent Handler, Nango, Paragon ActionKit, StackOne, Zapier MCP, Membrane, n8n and Apify. Which one is right depends on why you are leaving: tighter enterprise authorization, open-source code you can host, deeper coverage in one category, a different pricing unit, or a no-code workflow tool instead of an SDK.
Composio is an integration and tool layer for AI agents. It connects agents to more than 1,500 apps such as Gmail, Slack, GitHub, Notion and HubSpot, manages OAuth, API keys and token refresh for each end user, and exposes those tools through SDKs and MCP, including a managed MCP gateway. The free Hobby plan includes 100,000 tool calls per month, and the Pro plan starts at $29 per month plus usage.
That is a lot of ground to cover, which is why the market has filled with specialists. Agents now take real actions in customer systems, so teams care more about who holds the credentials, how permissions are enforced and where the code runs. This guide ranks ten options on those questions. For head-to-head detail, see our Composio vs Arcade vs Pipedream comparison.

Best Composio Alternatives In 2026
1. Arcade.dev — Delegated Agent Authorization With Self-Hosted Deployment
Arcade calls itself an actions runtime for production AI agents. Its central idea is delegated authorization: an agent acts as the authenticated user, authenticated against your identity provider, and every action runs at the intersection of what the user is allowed to do and what the agent is scoped to do. Pre- and post-tool-call hooks let you add custom policies, and the team says it authored the MCP tool authorization specification.
Choose Arcade instead of Composio when security and deployment control decide the deal. Enterprise customers can run it in Arcade Cloud, in their own VPC, on-prem or air-gapped, with SSO, RBAC and audit logs. The catalog lists more than 8,000 permission-aware tools, and custom tools are built with its MIT-licensed open-source MCP framework. In August 2026 Arcade acquired Smithery, the large MCP server registry, so discovery and runtime now sit under one company.
Pricing is transparent. The free tier includes 2,000 auth events and 2,000 tool calls per month. Team costs $25 per month plus $0.10 per auth event and $0.01 per tool call, and Enterprise uses annual bundles.
2. Pipedream Connect — 3,000+ APIs With Managed Auth And A Raw Proxy
Pipedream Connect gives developers managed auth, prebuilt tools and triggers, and a remote MCP server where tools run with each user’s connected accounts. Its catalog is one of the largest available, with more than 3,000 integrated APIs and over 10,000 prebuilt tools and triggers. When a prebuilt tool does not exist, the proxy lets you call any endpoint on those APIs with the user’s credentials attached.
The key ownership change: Workday agreed to acquire Pipedream in November 2025, and Workday’s annual report lists it among acquisitions completed in its fiscal 2026. Pipedream continues to operate and sell Connect. For buyers, the Workday backing can be a plus for longevity and a question mark for roadmap neutrality, so it is worth raising on a sales call.
Development access is free with no credit card. The Startup plan costs 150 monthly) and includes 100 external users and 10,000 credits, then $2 per user and $0.012 per credit. Business plans add SSO, SCIM, HIPAA support and SLAs.
3. Merge Agent Handler — Agent Tool Layer With Data Loss Prevention And Audit Trails
Merge built its name on unified APIs for HR, CRM, accounting and ticketing data, and Agent Handler extends that into agent tooling. It connects agents to thousands of pre-built tools and MCP connectors, prompts users to authenticate when an agent reaches an unconnected tool, and manages credentials from there. It installs as a remote MCP server for Claude, Cursor or ChatGPT and can import public MCP servers.
Why pick it over Composio: governance. Agent Handler scans tool-call inputs and outputs for sensitive data and can block, redact or mask it before it reaches a model or a third-party system. Every action is logged with identity, arguments, downstream API calls and outcome. Security teams that need to see exactly what an agent did tend to prefer this model.
The free plan includes 2,000 monthly credits and unlimited tool packs. Pro costs $1,000 per month for 25,000 credits, and Enterprise adds custom connectors, on-prem deployment and SIEM log streaming. Merge’s unified API is covered in our list of top unified API platforms.
4. Nango — Source-Available Auth And Code-First Tools You Can Self-Host
Nango is the pick for engineering teams that would rather write their own tools than rely on a vendor’s prebuilt ones. It handles auth for more than 1,000 APIs and MCP servers, ships about 7,000 pre-built tools, triggers and syncs as starting templates, and lets you extend them or build fully custom functions in code. The source is public on GitHub under the Elastic License.
Choose Nango as a Composio alternative when you need control over the tool definitions, the data each tool returns, and where everything runs. Self-hosting and bring-your-own-cloud are Enterprise options. Beyond tool calls, Nango’s syncs can keep fresh customer data available for RAG, which matters if your agent needs context as well as actions.
The free plan includes 10 connections and capped compute. Pay-as-you-go costs $50 per month in credits, billed at $0.29 per connection and $0.72 per compute hour. Enterprise adds commitment discounts, self-hosting and SLAs.
Paragon is an embedded integration platform for SaaS companies, and ActionKit is its agent layer: one API and MCP server exposing more than 1,000 integration actions across CRMs, ticketing, email and chat. Your agent fetches the available actions at query time and receives them as function-tool definitions, and it works with OpenAI, LangChain, Vercel’s AI SDK and other frameworks.
It beats Composio when agent tools are only part of what you need. The same vendor provides the Connect Portal your customers use to authorize apps, Workflows for event-driven integration logic, and Managed Sync for pulling files and permissions into retrieval pipelines. That bundle suits a product team shipping customer-facing integrations and an AI assistant at the same time.
Pricing is quote-based and scales with connected users. ActionKit is included in every plan, and Enterprise adds self-hosting and SAML SSO.
6. StackOne — Provider-Native B2B Actions With Built-In Agent Security
StackOne positions itself as an AI agent integration platform for B2B software. It offers more than 560 connectors and over 35,000 actions across HR, recruiting, finance, CRM, support and marketing, each available as an MCP server, plus A2A, REST and Python and TypeScript SDKs. Unlike unified APIs that flatten every system into a generic schema, StackOne keeps each provider’s own data model.
The reason to choose it over Composio is depth in enterprise business systems plus a security layer designed for agents: a prompt injection guard, PII redaction, tool policies and audit logging. An AI connector builder covers systems that are not yet in the catalog, and OEM plans let you embed StackOne inside your own product.
The Gateway Starter plan is free, with 1,000 credits per seat per month and access to all connectors. Team, Enterprise and OEM plans add the connector builder, agents, premium defense features and SAML SSO.
7. Zapier MCP — 9,000+ Apps For Teams Already Paying For Zapier
Zapier MCP connects AI clients such as Claude, ChatGPT and Cursor to Zapier’s catalog of more than 9,000 apps. The agent searches for the right action and runs it, and when no standard action fits, it can write custom code to reach an internal API. Useful sequences can be saved as reusable skills or deployed as Zaps that run on their own.
This is the right Composio alternative for operations teams and non-developers, not for SaaS companies building agents for their own customers. Credentials stay inside Zapier’s connection layer rather than passing to the model, and admins can control which apps and actions are allowed, review a log of every MCP action and switch MCP on or off per workspace.
Zapier MCP is included in every Zapier plan. Each tool call uses two tasks from your existing quota, so the cost depends on the plan you already have. If you are reconsidering Zapier itself, our guide on how to cancel Zapier covers the steps.
8. Membrane — AI-Built Connectors For Any API, Formerly Integration.app
Membrane, the company formerly known as Integration.app, takes a different approach to the catalog problem. Instead of relying only on pre-built connectors, its AI agents research an API, handle authentication, build the integration, test it and maintain it as the API changes. A catalog of pre-built connectors for apps such as HubSpot, Salesforce, Slack, Stripe and GitHub sits alongside.
Pick Membrane over Composio when your customers keep asking for niche or customer-specific systems that no catalog covers, or when you need per-tenant variants of the same integration. It works with agent frameworks through MCP, an SDK and Skills, and supports clients such as Claude, ChatGPT, Cursor and GitHub Copilot. Self-hosting in your own cloud, VPC or data center is available, along with SOC 2 Type II and GDPR compliance.
Membrane does not publish prices on its site, so expect a sales conversation.
9. n8n — Self-Hosted Visual Workflows With MCP Server And Client Nodes
n8n is a workflow automation platform rather than a tool SDK, but it has become a popular Composio alternative for teams that prefer building agent logic visually. Its AI Agent node calls tools inside a workflow, the MCP Client node lets those agents use external MCP servers, and the MCP Server Trigger turns any n8n workflow into a tool that outside agents can call. Human approval steps can gate sensitive tool calls.
The main draw is hosting. The Community Edition is free to self-host from GitHub under n8n’s Sustainable Use License, so credentials and data never leave your infrastructure. The trade-off is that you manage OAuth apps and connections yourself, which is fine for internal automation but less suited to a multi-tenant product where thousands of end users connect their own accounts.
Cloud plans are priced by workflow executions: Starter costs €20 per month for 2,500 executions and Pro €50 per month for 10,000, billed annually.
10. Apify — 7,000+ Web Data Actors As Agent Tools Through One MCP Server
Apify fills a gap that app-connector platforms leave open: the public web. Its MCP server gives agents access to more than 7,000 Actors and MCP servers through a single Apify API key, covering scrapers, crawlers and automation for sites that offer no API. Dynamic tool discovery lets an agent search for and add the Actor it needs mid-task.
Choose Apify instead of, or alongside, Composio when your agent’s job is research, lead enrichment, price monitoring or content extraction rather than acting inside a user’s SaaS accounts. You get one account and one invoice for many third-party scrapers, and you can publish your own Actors to the same marketplace.
The free plan includes $5 of monthly platform usage. Paid plans start at $19 per month (Starter), with Scale at $199 and Business at $999, each including the same amount in prepaid usage. Individual Actors may charge per event or per result on top of platform usage.
How To Choose A Composio Alternative
Who Holds The Credentials, And Whose Permissions Apply?
Every platform here stores end-user tokens, but they differ on what the agent may do with them. Arcade enforces the intersection of user and agent permissions, Merge and StackOne add data scanning and policies, and Zapier lets admins allowlist apps and actions. Write down your security team’s requirements before you compare catalogs.
Do You Need Open Source Or Self-Hosting?
If data residency or procurement rules require running the stack yourself, shortlist n8n (free self-hosted Community Edition), Nango (source-available, self-hosted on Enterprise), Arcade (VPC and air-gapped on Enterprise) and Membrane (self-hosting available). Check the license terms, since source-available is not the same as open source.
Is This An Agent For Your Customers Or For Your Team?
An agent tool calling platform for a multi-tenant SaaS product needs hosted connect flows, per-user credentials and white-labeling, which is where Pipedream Connect, Paragon, Nango and StackOne focus. An internal assistant for your own staff can run happily on Zapier MCP or n8n.
How Does Pricing Scale With Your Usage?
Pricing units vary widely: tool calls (Composio, Arcade), auth events (Arcade), external users (Pipedream), credits (Merge, StackOne), connections and compute (Nango), Zapier tasks or n8n executions. Model a realistic month with your expected users and calls per user before deciding, because the gap between options can be large.
