Closest free matches
Ranked by shared use cases, audience and stack with Antelog. Every tool here lists a free plan.
shim-cli is a free, Apache-2.0 command-line tool that hooks into Claude Code, Codex, Copilot CLI and VS Code to find secrets and personal data in what an agent sends, mask it where the client allows, and report session tokens and cost.
Beacon is an MIT-licensed tool from Asymptote Labs that captures session history from Claude Code, Cursor, Codex, OpenCode and 20+ other agent harnesses, normalizes it into one trace format, and turns useful workflows and corrections into reusable knowledge for future agents.
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.
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.
Polylane connects your code, cloud and observability data so AI agents can detect production issues, trace the root cause and open a pull request with the fix; Polylane for Cloudflare covers Workers, D1, R2, Queues and more with one read-only token.
telemetry.dev is a hosted LLM observability platform built on OpenTelemetry that shows each AI agent run as one trace of model calls, tool steps and retrievals, with token, cost and latency tracking, MCP analytics, alerts, prompt management and evals.
Paxper is a visual infrastructure-as-code platform: draw your AWS setup on a canvas, get standard OpenTofu and a readable plan with cost estimates, approve it, and apply it in your own account. An MCP server lets AI assistants edit diagrams without touching the cloud directly.
OpenMail is email infrastructure for AI agents: one API call or CLI command gives each agent its own inbox and address, inbound mail arrives over a webhook or WebSocket with attachments parsed to text, and replies stay in thread, with EU data residency on every plan.
Give your agent a backend. Models, auth, database and storage in one cloud — from demo to production.
Clayzo is an animation engine and CLI built for coding agents: Claude Code, Codex or Cursor write motion graphics as typed TypeScript documents, render frames to check their own work, then export video or play the animation live on the web or natively in Swift.
Skillbox keeps your AI coding agents' skills in one library, tracks their GitHub/GitLab sources, scans every version for prompt injection and secrets, and syncs only the skills you choose to Claude Code, Cursor, Codex and 11 more tools. Free; Trim and AI from £6.99/month.
ProtoMap by HoundDog.ai statically maps every gRPC service, protobuf message, caller and field flow across your repositories and serves that graph to coding agents over MCP, so they stop re-grepping the codebase to find dependencies.
