Closest free matches
Ranked by shared use cases, audience and stack with CALL-E. Every tool here lists a free plan.
Composio connects AI assistants and custom agents to more than 1,500 apps through managed authentication, SDKs and an MCP gateway, and its new Instant tools let agents pay per call for search, scraping, audio and data services from one balance.
Pomerado builds deterministic MCP and API integrations for websites without an API, including sites behind logins and 2FA, so agents call a tool instead of driving a browser. Open-source core (MIT) plus a hosted cloud.
BAND is interaction infrastructure for AI agents: agents built on different frameworks join shared rooms where they exchange context, delegate work and ask humans for approval. Band Desktop brings this to local coding agents such as Claude Code, Codex and OpenCode.
UnleashX is a Gurugram-based AI workforce platform where companies hire pre-built AI employees or build their own to handle calls, chat, email and WhatsApp work, inside their CRM and business systems, with scoped access, approvals and a named human owner for every exception.
MachineMail is an email API for AI agents: free inboxes on demand, a hosted MCP server and webhooks, and a trust report on every inbound message that strips hidden instructions and tells the agent whether the sender can be believed. Its /v0 API is compatible with AgentMail's.
Rerun lets teams hire AI "coworkers" that work on a schedule or trigger inside a private cloud computer, connect to thousands of apps and MCP servers, ask before consequential actions, and run on a Claude or ChatGPT subscription, an API key or included credits. It is open source under AGPL-3.0 and can be self-hosted.
Scalekit is an authentication stack for AI agents and B2B apps. Its AgentKit product puts 600+ connectors and 30,000+ tools behind one MCP gateway, with per-user OAuth, scoped tool sets, event triggers and audit logs, so agents can act in users' apps without your code ever holding a token.
