How I Use Claude Code, Gemini, and Codex from One Interface with Bifrost CLI?
Summary
Bifrost CLI offers a unified interface for managing multiple AI coding agents like Claude Code, Gemini, and Codex, addressing the fragmentation issues arising from their disparate authentication, URLs, and configuration patterns. It operates by routing all agent interactions through a central Bifrost gateway, which acts as an OpenAI-compatible AI gateway providing features such as observability, governance, caching, failover, and load balancing. This setup allows developers to launch and switch between different coding agents and flexibly select models from various providers (e.g., using an Anthropic model with Codex) through an interactive terminal UI, eliminating the need for manual configuration adjustments for each tool. The CLI also supports persistent tabbed sessions and secures virtual keys in the OS keyring.
Key takeaway
For AI Engineers and Software Developers managing multiple AI coding agents, Bifrost CLI streamlines your workflow by providing a single interface for Claude Code, Gemini, and Codex. This allows you to switch agents and models seamlessly without repeated configuration, enhancing flexibility and reducing setup overhead. Consider integrating Bifrost CLI to centralize your AI coding environment and improve model experimentation.
Key insights
Bifrost CLI unifies AI coding agent workflows by routing diverse models through a single gateway, simplifying multi-agent development.
Principles
- Universal model access
- Gateway-backed workflow
- Interactive configuration
Method
Launch Bifrost gateway, then Bifrost CLI. Select coding agent (harness), choose model, and configure session settings via an interactive terminal UI. The CLI handles base URLs, API keys, and model settings automatically.
In practice
- Compare agent behavior on identical tasks.
- Experiment with cross-provider model choices.
- Reduce setup friction across multiple agents.
