Description
Hi HN, we’re building AxonFlow for teams running LLMs or agents in real production systems.Once agent workflows move past demos, failures are rarely model issues. They tend to show up as execution problems during real runs.Short 2-minute technical demo showing execution control and auditability in practice: https://youtu.be/FNgnESo9RtIAxonFlow is a self-hosted, source-available (BSL 1.1) control plane that sits inline in the execution path and governs LLM calls, tool calls, retries, approvals, and policy enforcement step by step. It does not replace your orchestrator and can run alongside LangChain, CrewAI, or custom systems.The problems we focus on are usually discovered only after going to production: - retries that accidentally repeat side effects - partial failures mid-workflow - permissions that differ per step - limited ability to inspect or intervene during executionThis is not aimed at early demos or hobby projects. It’s for teams already operating under real production constraints.GitHub: https://github.com/getaxonflow/axonflowDocs: https://docs.getaxonflow.comI’d value feedback from folks running LLM or agent workflows in production.

Could you build this?
No AxonFlow is an enterprise-grade runtime governance and execution control plane for agent workflows. Building deterministic guardrails, policy enforcement proxies, and auditability at low latency requires specialized distributed systems and security engineering.
What it would actually take: The architecture comprises an ultra-low-latency reverse proxy (Go or Rust) intercepting LLM/tool calls, evaluating deterministic policy engines (e.g., OPA/Rego), enforcing execution state transitions, and writing immutable audit logs. The primary difficulty is inline policy enforcement and state-machine validation without adding latency or breaking streaming connections. It requires deep expertise in systems programming, enterprise security, and proxy architecture.
Discussion
14 comments analyzed.
Competitors mentioned: LangChain, LangGraph, CrewAI, Kaos (kaosThere)
Concerns raised: Migration cliff from gateway to proxy mode without rewriting orchestration code, Policy complexity becomes bottleneck beyond simple PII/SQLi rules, Tail latency (p95, p99) with overlapping policies and cold cache not benchmarked, Risk of becoming orchestration layer competing with LangChain/CrewAI, Latency overhead relative to non-LLM operations like tool calls
Feature requests: Image redaction support, Deterministic replay for stateful workflows, Policy simulation and staged rollout tooling, Performance benchmarks with complex rules and cold cache scenarios
