Cycles
Self-hosted, Apache 2.0 runtime authority that gates autonomous agent spend and risky actions pre-execution
0About Cycles
Cycles is a runtime authority layer that stops autonomous agents before they spend too much or take a risky action, rather than reporting on it afterwards. Gating happens pre-execution against cost and risk criteria and against the specific tool action being attempted, which is the difference between a control and an audit log. It is self-hosted with no prompt storage and licensed Apache 2.0, so the enforcement path runs inside your own infrastructure and the code is inspectable — an important property for something sitting in front of every agent action. The published operational numbers are unusually specific for this category: a shared reserve at 34ms p99 for a single client and 891 reserves per second, with 4 SDKs, durable recovery and 12/12 on each, plus a documented fail-closed behaviour on reserve-time outage, which is the correct default for a spend control. Over 21,292 package installs are reported. Documentation covers a protocol spec, interactive API and admin API references, integration guides, security and incident patterns, and there are free calculators for blast radius, risk and Claude-versus-GPT cost. Self-hosting is free; the paid tiers are support and services contracts rather than software licences.

Key Features
Cycles Pros & Cons
✅ Pros
- +Pre-execution gating is a real control, unlike the after-the-fact dashboards most competitors ship
- +Apache 2.0 and self-hosted means the enforcement path is inspectable and never leaves your infrastructure
- +Fail-closed default is the correct safety posture and is documented explicitly
- +Concrete latency and throughput numbers rather than unquantified performance claims
- +The core software is free — you pay for support, not for the control itself
⚠️ Cons
- −$18,000/year minimum for supported production use is enterprise-scale pricing
- −Self-hosting means you own the operational burden of a component in the critical path
- −Adding a gate before every tool call introduces latency and a new failure mode
- −Only relevant once agents have genuine spend and action authority
