Statewright takes a provocative stance on AI agent reliability: instead of making models smarter, restrict what they can do. The framework lets you define explicit state machines that determine which tools an agent can access at each phase of a workflow. During planning, agents get read-only tools. During implementation, edit tools unlock. During validation, only test commands are available. The philosophy is captured in a single line from the README: "Agents are suggestions, states are laws." The core engine is written in Rust for deterministic, zero-LLM evaluation of state transitions. Plugin layers integrate with agents via MCP (Model Context Protocol), enforcing tool restrictions at the protocol level across most major platforms. The framework is Apache 2.0 for its core engine, with FSL licensing for extended features (converting to Apache 2.0 in 2029, self-hosting allowed for developers and teams now). The team published SWE-bench results showing models jumping from 2/10 to 10/10 success rates on five tasks when Statewright constraints were applied—a striking claim that has the HN crowd both skeptical and intrigued. This is genuinely novel territory: rather than prompt engineering or fine-tuning, it's architectural guardrails enforced at runtime. For production agent deployments where agents interacting with dangerous tools (databases, file systems, APIs) need hard constraints, this fills a real gap. 53 stars so far, but the HN traction suggests it's about to pop.
Reviewer scorecard
“4x the compute per dollar compared to AWS. European data centers for GDPR compliance. The best value in cloud computing.”
“Rust deterministic engine enforcing MCP-level tool restrictions is exactly the kind of hard guarantee you need before letting an agent touch production databases. This is infrastructure, not a toy.”
“Unbeatable pricing if you can manage your own infrastructure. Not for teams that need managed services.”
“The SWE-bench jump from 2/10 to 10/10 on five tasks is too small a sample to generalize from. Rigid state machines may reduce agent flexibility in ways that create new failure modes—agents that get stuck because a valid path violates the state graph.”
“As cloud bills become a board-level concern, Hetzner's value proposition becomes more compelling every quarter.”
“Formal methods for AI agents—think type systems but for behavior—is a research area that will matter enormously as agents enter regulated industries. Statewright is an early, practical instantiation of that idea. Watch this space.”
“For creative workflows where spontaneity matters, hard state machine constraints sound like they'd kill the magic. I'd rather have a guardrail-light agent that occasionally needs correction than one that asks permission to proceed at every step.”
