3. fx (by Vercel) — best for researchers building and testing coding agents with minimal dependencies

Pricing: Free · Free plan: Yes · Upvotes: 211

In fx (by Vercel)'s words

fx is Vercel's tiny, open-source coding agent built to get out of your way. Written in Zig and shipped as a ~6MB native binary, it starts almost instantly while keeping memory and context overhead low. Use it with local or cloud models, extend it with skills, plugins and MCPs, or embed it into your own agent infrastructure. Small by design, so the model gets more room to work.

Key features

• Run as a tiny native binary installable in terminal or CI
• Embed as a library in Node.js or WebAssembly applications

Use cases

• Researchers building and testing coding agents with minimal dependencies
• Teams integrating AI coding capabilities into CI/CD pipelines

4. OpenComputer — best for developers who want to deploy long-running autonomous agents without managing infrastructure

Pricing: Free plan; paid from $10 · Free plan: Yes · Upvotes: 141

In OpenComputer's words

Deploy your agent as a function, get a computer for it. 1. Write an agent as a TypeScript function. Deploy it. We run the loop, the sessions, streaming etc 2. Every session runs on a real Linux machine. 3. Your tools and MCP servers run on that machine - clone a repo, run ffmpeg, drive a browser, install anything. 4. Sessions are durable: can be steered mid-run, hibernate when idle, resume where they left off. 5. No model keys in your runtime. Bring your own or use our managed gateway.

Key features

• Run agents on full Linux virtual machines with hardware-level isolation
• Checkpoint, fork, and resize memory and CPU at runtime
• Deploy agents as TypeScript functions with one command
• Keep model API keys outside the runtime for security
• Schedule agents to run automatically on a cron schedule

Use cases

• Developers who want to deploy long-running autonomous agents without managing infrastructure
• Teams automating code changes by running agents that edit code, run checks, and open PRs

Pricing details: Free $10 credit to start. Pro plan $20/month with 10× prepaid credit. Max plan $200/month. Pay-as-you-go rates for model calls at API prices and machine time billed per second.
