A language to define what agents do. A machine to run them. One CLI to manage it all.
Crumbs is a purpose-built language that turns complex agent workflows into something you can read, review, and version like any other code. One file defines what agents do, what they can access, and how work flows between them.
Each workflow runs in a fully isolated environment on a hosted machine. Run hundreds in parallel and they never touch each other. No shared state, no interference, no surprises.
Every agent is fully locked down by default. You declare file access, tools, and permissions upfront in the workflow. No runtime permission prompts. No guessing. Agents run flawlessly every time because the boundaries are clear before they start.
Every action, every file, every decision lives on the filesystem. Read agent outputs, inspect logs, and trace execution with the same tools you already use. Nothing is hidden.
Agents working on the same job share knowledge and coordinate through built-in channels. They hand off context, flag blockers, and build on each other's work. The result is smarter than any single agent working alone.
Agents capture what they learn as they work. Patterns, edge cases, domain knowledge. Future runs get that knowledge automatically. You can contribute your own insights too.
Built-in evals and feedback loops so you know exactly how your workflows are performing. Define what good output looks like and let the system tell you when it falls short.
Patterns emerge across runs. Insights compound. The system learns from its own output and improves over time without you having to babysit every run.
Bring your own tools and temporarily attach your computer to a cloud machine. Agents can work on your local files within the boundaries you set. When you disconnect, access stops.
Bring your own API keys and use the provider plans you already pay for. Works with OpenAI, Anthropic, Codex, Claude Max, and more.
Manage workflows, inspect runs, read memory, browse the filesystem, and debug from a single command line. The same CLI works for humans and AI agents.
Need more capacity? Spin up another machine. Same workflows, more throughput. Each machine runs independently with its own filesystem, memory, and run history.
Crumbs is in early access.
