SEPIA vs SmythOS

SEPIA is an open-source framework and cross-platform app for building a customizable digital voice assistant with a self-hosted server. The server runs core functions such as the database, account management, natural-language understanding and chat. Users can make commands in the app, build voice-controlled services with the Java SDK or replace framework modules. SEPIA accepts spoken or typed requests and can ask follow-up questions when a service needs more detail. Documented services include news, radio, timers, alarms, reminders, to-do and shopping lists, smart home, navigation, weather, Wikipedia and web search. The documentation names openHAB as a smart-home integration, and SEPIA-Home v2.7.0 release notes add Home Assistant support. Speech recognition can use native platform APIs or a custom open-source STT server; text-to-speech can use native APIs or compatible server tools. Client use is described for desktop browsers, Android and iOS; iOS instructions use Safari and adding the app as a PWA. Server guidance covers Windows, Mac, Linux and Raspberry Pi. SEPIA says users control their data in a self-hosted environment, but it does not currently host public servers, so users need access to their own server or one provided by someone else.

SmythOS is an orchestration platform for designing, observing, and deploying AI agents. Its Studio provides a drag-and-drop workspace for agents and workflows, while Agent Weaver can create, troubleshoot, and revise workflows from conversational prompts. Agents can be deployed through chat, APIs, webhooks, MCP servers, and ChatGPT, or exported to run locally. Connections include Slack, Trello, GitHub, and Stripe, alongside OpenAPI and Postman collections. The platform supports models from OpenAI, Anthropic, Hugging Face, and customer-provided sources. Deployment options include local, on-premises, VPC, and SaaS; the maker describes access controls and isolated agent contexts. A free plan is available, and paid plans start at $39 a month. Fast API call allowances vary by plan, from 100 per day on Builder to unlimited on Enterprise. Built-in model use is charged separately according to usage. SmythOS runs on web, Windows, macOS, Linux, API, and self-hosted environments, and is headquartered in Houston, Texas.
