systemprompt.io is the only AI infrastructure you actually own. It is a single Rust binary that holds every governance decision, every audit record, every policy evaluation, and every agent interaction in one place, running inside your perimeter on hardware you control.
It is built to one standard, applied everywhere. Architectural consistency across every module, every extension, and every migration, so the system behaves the same on a laptop as it does in production. That is the standard it was built to, and it is the standard it is held to on every build.
Built to survive scrutiny.
This codebase has been through technical due diligence at some of the largest tech companies in the world, and human code review from Rust maintainers. It held.
The live load test is the shortest version of the story: 200 concurrent governance requests, each running full validation, scope resolution, three rule evaluations, and an async database write. Sub-5ms p50 latency. Sub-10ms p99. Throughput that supports hundreds of concurrent developers on a single instance.
The proof points are on the public record. Copyright registered with the USPTO. Published on crates.io. Source-available under the Business Source License 1.1, so buyers can read every line before they commit. Multiple production deployments running today, including the site you are reading right now, its marketplace, its MCP servers, and its content pipeline. One binary plus one database, for everything.
Rust. PostgreSQL. One binary.
One language. One database. One binary, roughly 50MB. No Kubernetes. No message queues. No service mesh. Copy the binary to a server with PostgreSQL, start it, and that is the deployment. It runs air-gapped from day one.
It is built on open standards that outlast any single vendor: MCP for agent-tool communication, implemented natively rather than proxied, A2A for agent interoperability, and OAuth2 with OIDC for authorization. Leaving is a copy, not a migration.
How we work with buyers.
There are no layers between you and the people who understand the product. Evaluation, architecture questions, and licensing all go directly to the engineering team that built the system. Delivery is led by the engineer who wrote it.
Licensing is annual, with support and updates included. The source is available under BSL 1.1 and converts to Apache 2.0 after four years, so the terms have an end date you can read today. For enterprises that require ownership, we hold full IP and can structure agreements that grant IP rights under defined circumstances. Everything your teams build on the system, its tools, Skills, settings, and records, is your property.
Evaluate it without a sales process.
You can prove the whole system on your own machine before you ever talk to us.
- Clone the template from GitHub. Run it with Docker or compile from source. The full governance pipeline is in the box.
- Read the documentation. Deployment guides, API reference, and configuration are public.
- Talk to us when you are ready. Once you have seen it running, reach out about implementation, licensing, or custom integrations.
