What it actually does
The pitch is narrow and honest: the most RAM-efficient agent harness. Written in Rust, distributed as a single binary, installed with one curl command on macOS and Linux or one PowerShell line on Windows.
If you have watched a JavaScript-based agent harness consume several gigabytes of memory while you also have a dev server, a browser, and Docker running, the appeal is immediate. Efficiency is not a marketing angle here, it is the entire product thesis.
It is a terminal TUI with MCP support, works across OpenAI and Anthropic-compatible providers, and ships an SDK and published benchmarks — the maintainers are willing to be measured, which is more than most.
At 16,600 stars and MIT licensed with active daily pushes, it is young but moving fast.
Who it's for
- 01
Developers on memory-constrained machines who cannot spare four gigabytes for an agent
- 02
Teams running several agent sessions in parallel on one machine
- 03
People who want a single binary rather than a Node runtime and a dependency tree
- 04
Anyone running agents on small cloud instances where RAM is the cost driver
Where it earns its keep
- Running multiple concurrent agent sessions without exhausting system memory
- Agent work on an older laptop that struggles with heavier harnesses
- Deploying an agent onto a small VPS where memory determines the bill
- CI environments where a lean binary beats a runtime install
- Comparing harness performance honestly against published benchmarks
Use it, or skip it
Reach for it when
- Memory is your actual constraint, not model quality
- You want one binary with no runtime dependencies
- You run several agents at once on the same machine
- Small-instance hosting costs are driven by RAM
Skip it when
- You need a mature plugin ecosystem — this is newer than the established harnesses
- You prefer a graphical interface; this is terminal-first
- Your machine has memory to spare and you would rather have breadth of features
- You need enterprise support rather than a Discord and a GitHub issue tracker
10 automations
Ideas, not tutorials. Each one is work a team does by hand today.
- 01Engineering
Parallel agent sessions
Run one agent per service in a monorepo simultaneously on a single developer machine without swapping.
- 02Engineering
Cheap CI agent runner
Use the single binary in CI to run agent-driven checks without provisioning a Node runtime per job.
- 03Finance
Small-instance automation host
Host recurring agent jobs on the smallest viable VPS tier and report the monthly saving against your previous setup.
- 04Operations
Standard team install
Ship one install command in your onboarding docs so every engineer has an identical agent setup on day one.
- 05Operations
MCP tool hub
Register internal MCP servers once so the whole team's agents can reach the same internal tooling.
- 06Engineering
Benchmark-driven selection
Run the published benchmarks against your own workload to pick a harness on evidence rather than preference.
- 07Operations
Resource-usage alerting
Track agent memory footprint across the team and flag when a session behaves abnormally.
- 08Operations
SDK-driven internal tooling
Build a thin internal CLI on the SDK so non-engineers can trigger approved agent tasks safely.
- 09Finance
Legacy hardware revival
Give older machines a useful second life as agent runners rather than replacing them.
- 10Engineering
Provider failover
Configure multiple compatible providers so a rate limit on one does not stop the day's automated work.
