Smyth Runtime EnvironmentThe agent operating system for the agent economyStateful, secure, modular.Meet SREBuilt from first principles, we designed an agent operating system to meet the needs of developers and enterprises.Freely available to all humanity under the MIT license, and inspired by the elegance of the Linux architecture, we invite you to build the future with us.Command Line InterfaceSRE CLIGet it on GitHub Get it on GitHub Cross PlatformRuns anywhere: local, cloud, or edge. Fully cross platform: linux, mac, windows.ObservableBuilt-in monitoring and debugging tools.ModularSwap any component without breaking the system.Blazing FastJust 50MB, ultra-efficient architecture for multi agent orchestration.Optimized for high-throughput AI operations.Purpose BuiltDesigned from the ground up, specifically for AI agent workloads.We built the kernel to power the internet of agents, and then open sourced it.Security-FirstEnterprise-grade security from day one. Done for you.Elegant and CleanSRE SDKGet it on GitHub Get it on GitHub Set Up and Run AI AgentsLearn how to create and run AI agents using our CLI and SDK, and connect them to the MCP server for full integration.SecureEnough autonomy to matter, enough control to trustOmniGuardIntercepts each resource request and verifies embedded security tokens against agent permissions.Key VaultYour API keys are stored in an AES-256-encrypted vault. Secrets never touch disk or code, so credential leaks stop here.Logs & Audit TrailsDetailed immutable logging of all agent actions and access attempts for compliance reporting, fine-tuning and incident investigation in Agent Studio.Robust DebuggingTesting different use cases quickly and understanding exactly how the agent behaves is key to creating secure solutions.TransparencySecurity begins with understanding what your agent does. SmythOS can visualize more logic than any other platform.SandboxedComponents are fully sandboxed to prevent data leakage.Hot LoadingSwitch and add AI models on the fly without requiring a rebuild or redeploy.Open SourceWe have open sourced our runtime environment (SRE), command line (SRE CLI) and development kit (SRE SDK) under the MIT license.We are preparing to open source our visual builder.If you can’t contribute to the codebase, consider supporting our discord community.Star us on GitHub ControlSafe agents are economically valuable agentsAligned AutomationSmythOS architecture natively air gaps components and data flows on a “need to know” basis. Components are unaware of each other, act independently, with zero data leakage.In this example, the AI model never gets to discriminate based on the person’s identity, and the patient privacy is respected.Language ChainsLet one model refine the output of a previous AI model.Agent ChainsLet one agent evaluate the output of another agent.Human in the LoopLet a human verify the output of an AI model or agentTree of ThoughtLet one model refine outputs of several other AI models.Reasoner ChainsPerform deep thinking from different models and perspectives, then evaluate.GroundingAugment AI reasoning with grounding over RAG, API, SQL and more.Catch them AllDesign agents the way you put human teams together for outcomes that are secure, grounded, reviewed, and refined.Developers Love SmythOSJoin over 20,000 developers who build with Weaver.Eric HeydenberkCTO & Founder at QuotaPathOld-School development is Extinct!Welcome to the future of development. When I first hear about developing with AI I thought that I would lose control but WOW SmythOS nails it. It’s really mind-blowingly shocking how well it works.ConsultingThursdayAtakan OzuysalFounder at B2BReachAI-Powered Genius at Your FingertipsNever thought ‘easy’ and ‘AI development’ could be in the same sentence. SmythOS makes me feel like a tech wizard – it’s AI-powered genius that’s so easy to use.MediaTuesdayBrook OldreCTO & Founder at PerformixI love this agent builder 💯SmythOS is a fantastic platform. As a CTO with backend engineering experience this builder is gold! It will save me a ton of time building APIs. The ability to drag & drop AI models with my data and then just click deploy is awesome. 🔥AgencyThursdayBrian BorackCOO at Customer TimesThe Backend BuddyI used to dread backend work, but SmythOS is the buddy I needed. It’s like having a backend expert by your side, ready to take on any challenge with you.AgencyWednesdayGreg GillanConsultant PPDM CPDADev Life, UpgradedSmythOS is a revolution for developers.
