systemprompt - AI Agent Infrastructure

SystemPrompt.io is a Rust library that helps developers quickly build and deploy AI agents. It packages all the necessary AI infrastructure into a single, small program that is ready for production. This means developers can create agents that remember users, learn from their performance, and even talk to each other.

Benefits

SystemPrompt.io gives developers full ownership of their AI agent's code and deployment. Because it's a library, developers compile it into their own program, which they can then run on their own servers or cloud accounts. This prevents being locked into a specific platform and avoids needing extra software to run the agent. The system also allows agents to check their own performance and make changes on the fly, improving their behavior over time. Developers can also add their own custom features and logic by creating extensions that are included when the agent is built.

Use Cases

Developers can use SystemPrompt.io to build a variety of AI agents. These agents can be deployed to personal cloud servers or custom domains. The system is useful for creating agents that need to remember user interactions across different sessions. It's also suitable for applications where agents need to analyze their own performance and adapt their behavior in real time. The ability to compile extensions directly into the agent makes it flexible for custom integrations and specialized tasks.

Pricing

SystemPrompt.io offers a free source-available option under a BSL-1.1 license, which converts to Apache 2.0 after four years. This free version includes self-hosting capabilities, support for bringing your own keys for AI models, all core features, unlimited agents, and community support. For those who prefer managed services, a Cloud option starts at $29 per month, providing managed hosting, easy deployment, and support. There is also a Licensed Enterprise option for businesses needing private infrastructure, dedicated support, and service guarantees.

Vibes

SystemPrompt.io is described as a library that developers control, differentiating it from frameworks that offer abstractions developers don't manage. Users can debug through their own code, and the resulting binary is owned and debuggable. The system is built on open standards, allowing for proprietary logic to be built on an open core.

Additional Information

The library is built using Rust and compiles into a single binary of about 50MB. It supports extensions that can add HTTP routes, database tables, background jobs, and custom AI model providers. These extensions are discovered during the build process. The system uses OAuth2/OIDC for API authentication and WebAuthn for passwordless login, ensuring all interactions are secure.
