aci vs open-connector
aci: ACI.dev is an open-source tool-calling platform designed to connect over 600 tools to any AI agent or agentic IDE. It provides intent-aware tool access with multi-tenant authentication, granular permissions, and dynamic discovery through a Unified MCP server or a lightweight SDK.; open-connector: OpenConnector is an open-source connector gateway that allows AI agents and applications to connect to over 1,000 providers and utilize 10,000+ prebuilt actions. It centralizes credential management and exposes a unified catalog, enabling robust and inspectable access to various user application accounts without exposing sensitive data to agent processes.

01
TL;DR
aciAPI Integration · ★ 4.9k
When to choose:
- You want 600+ pre-built integrations with built-in OAuth and secrets management, so you do not write a client per service.
- You want dynamic tool discovery so tool definitions stay out of the context window.
- You want to use it as an MCP server or through Python and TypeScript SDKs, with no framework lock-in.
When to skip:
- You want a single MCP server to install: the MCP server lives in a separate repository, and self-hosting runs a backend plus a portal.
- You do not want user credentials and tool calls to pass through a third party: that is how the managed service works.
- You need a very actively developed project: our data shows the last push on 2026-05-28.
open-connectorAPI Integration · ★ 6.1k
When to choose:
- You want your agents to use 1,000+ app integrations without handing provider credentials to the agent process.
- You want a self-hostable alternative to Composio, runnable with Docker, on Fly.io or on Cloudflare Workers.
- You want inspectable Action contracts (schemas, required scopes, executor source) with scopes, runtime tokens and allow and block policies.
When to skip:
- You need deep coverage of one service: integration depth varies across 1,000+ providers.
- You want no vendor path at all: hosted authentication and the commercial runtime come from OOMOL, and self-hosting means you run the runtime yourself.
- You do not want to connect and manage each provider's account, credentials and scopes.
