An open-source platform for managing LLM applications with prompt versioning, gateway, tracing, tools and evaluation in one control plane.
What it is
AcruxCore is an open-source LLMOps platform that sits between applications and model providers. It provides prompt versioning with named aliases, an OpenAI-compatible gateway for routing and tracing LLM calls, a versioned tool catalog for function calling, evaluation capabilities to score prompt versions, and a complete audit trail of every change. Teams can ship, change, and measure LLM features without redeploying—move a production alias between prompt versions in seconds and see the results immediately.
Systems
- Prompt versioning with named aliases and diffs
- Server-side prompt templating with conditionals and loops
- OpenAI-compatible AI gateway with automatic model fallbacks
- Virtual keys, budgets and per-key rate limits
- LLM tracing through the gateway or over OpenTelemetry
- Versioned tool catalog for function calling
- Offline experiments and online evaluation rules
- Prompt optimization with candidate rewrites
- Team-wide audit trail of every change
- MCP server for Claude Code, Claude Desktop, Cursor

Quick answers
- What is AcruxCore?
- AcruxCore is an LLMOps platform for managing applications built on large language models. It includes prompt versioning, an OpenAI-compatible LLM gateway, tracing, a tool catalog, and evaluation. The gateway records each model request that passes through it. If you do not use the gateway, your application can send its traces to AcruxCore directly. AcruxCore is licensed under Apache 2.0, so you can self-host the platform.
- What problems does AcruxCore solve?
- AcruxCore lets a team change a prompt without redeploying the application. It shows what happened inside each model call. Prompt versions live in one place that the whole team can edit. The gateway records each request that passes through it. The tool catalog stores tool definitions next to your prompts so the model can call them without extra code.
- How much does it cost and is there a token markup?
- AcruxCore is free during beta. Self-hosted is free under Apache 2.0 license. You bring your own provider keys and the provider bills you directly at their rates. We never add a markup on tokens—the gateway's job is to tell you what each call costs, not to sit in the middle of the invoice.
- Is my data locked in?
- No. Any prompt version can be exported as portable JSON and imported elsewhere, and traces are readable over the API. Deleting your account removes the associated data.
- What is the difference between a trace and an audit event?
- A trace records traffic your application sent: one model call, its prompt, its tokens, its latency and its cost. An audit event records a change a person made, and names that person. A trace answers why one model answer came out wrong. An audit event answers who changed the prompt on Tuesday, and what it said before. A model answer never becomes an audit event, and a role change never appears in a trace. AcruxCore keeps traces and audit events, and both are on by default. See core concepts for how traces, prompts, versions and audit events relate.
