HarnessRouter Community Edition vs SayGM

HarnessRouter Community Edition is an open-source, unified interface for agent harnesses designed for developers and AI infrastructure builders. Released under the Apache 2.0 license, it allows you to easily plug and play managed agent harnesses—such as Codex, Claude Code, and Hermes—into your products through a single API on your own infrastructure.

With HarnessRouter, you can seamlessly switch between different agent harnesses without having to rebuild your backend. The tool handles complex state operations out of the box, including sessions, streaming, files, artifacts, cancellation, and failure recovery. Furthermore, your model provider keys, state, and deliveries remain completely under your control, packed conveniently into a single Docker container containing the Gateway, Runner, and Console.

SayGM is a developer-focused, cost-effective, and highly private alternative to platforms like OpenRouter. Designed to bridge the gap between unified model access and strict data privacy, SayGM offers a single OpenAI-compatible endpoint that allows you to seamlessly access major frontier models—including Claude, GPT, and Gemini—without requiring code rewrites.

While many AI providers rely on basic text guarantees on their privacy pages, SayGM proves its privacy claims cryptographically. The gateway operates inside an Intel TDX enclave, enabling the silicon chip itself to sign a measurement verifying the exact software running. For open models, execution happens entirely within the secure enclave to ensure no one intercepts your prompts. For closed models, data remains strictly sealed for the maker alone, giving developers unmatched transparency and security in their AI infrastructure.
