GOModel is an open-source AI gateway written in Go that exposes a single OpenAI-compatible REST API across 10+ model providers — OpenAI, Anthropic, Gemini, Groq, xAI, Azure OpenAI, Ollama, and more. Unlike Python-based alternatives such as LiteLLM, it ships as a tiny single binary with a sub-10MB footprint, claiming 44x lower resource usage. The gateway ships with a two-layer caching system: an exact-match semantic cache that achieves 60–70% hit rates on repetitive workloads, plus a semantic similarity cache using embedding distance. It also includes Prometheus observability, structured audit logging, and configurable guardrails pipelines — making it suitable for teams that need compliant, observable AI routing without standing up a heavy Python service. For indie teams and self-hosted AI infrastructure, GOModel fills a real gap: a production-ready proxy that doesn't require a DevOps team to operate. It's particularly appealing for projects running on ARM boxes, Raspberry Pis, or edge servers where a Python runtime is a liability.

oh-my-codex (OMX)
Oh-my-zsh but for OpenAI Codex CLI — agent teams, hooks, and structured workflows

oh-my-codex (OMX) is an open-source orchestration layer for OpenAI's Codex CLI, created by Yeachan-Heo. The framing is dead simple: like oh-my-zsh extended the terminal, OMX extends Codex CLI with structured multi-agent workflows, customizable hooks, persistent memory, and a heads-up display (HUD) for monitoring agent activity. It hit 2,867 GitHub stars within days of going trending in early April 2026. OMX's key innovation is team-based execution: rather than one AI agent working through a task linearly, OMX spawns specialist roles — planner, implementer, reviewer, tester — each running in an isolated git worktree to prevent conflicts. The $deep-interview workflow gathers context before starting, $ralplan creates a structured action plan, and $team coordinates the parallel execution. It also adds native Codex hook ownership with PreToolUse/PostToolUse guidance, and ships with Windows and tmux reliability improvements. The practical use case: you have a complex feature to build across multiple files, and you want Codex to plan it properly before touching any code, run specialists in parallel for different modules, and produce a PR-ready result. OMX is that layer. It's explicitly for power users who already live in the terminal and find vanilla Codex too unstructured for serious projects.
Reviewer scorecard
“Finally a Go-native AI gateway that isn't a Python container in disguise. The two-layer caching alone pays for itself in API costs on any repetitive workload. Self-hosting this on a small VM is trivially easy compared to standing up LiteLLM with all its dependencies.”
“If you use OpenAI Codex CLI daily, OMX is an immediate productivity upgrade. Structured $deep-interview → $ralplan → $team workflows mean Codex actually understands the codebase before writing, and isolated git worktrees for parallel specialists eliminate the merge conflicts that kill multi-agent coding sessions.”
“128 stars on a December 2025 repo is not production pedigree. LiteLLM has years of battle-testing, a huge community, and an enterprise tier. 'Lighter' is nice but if GOModel drops a response or misroutes a call at 2am, there's essentially no support community to help you.”
“This is a power-user wrapper on Codex CLI, which itself is still early-stage software. You're now debugging two layers of abstraction when things break. The hook system is clever but brittle — and the project is maintained by one developer. Evaluate your risk tolerance before making this a team dependency.”
“As AI routing becomes infrastructure-layer plumbing, the winner won't be the Python monolith — it'll be the tool that deploys in milliseconds to any compute environment. GOModel's architecture is aligned with where edge AI inference is heading.”
“Multi-agent coding with isolated worktrees and structured pre-work phases is the right abstraction for complex software. OMX ships this today in a scrappy, hackable form that feels like a preview of where all coding agents are heading in 18 months. The project may get superseded — but the pattern it establishes won't.”
“For any creator running local AI workflows, having a dead-simple unified API across providers removes so much friction. Swapping from Anthropic to Gemini for different tasks without rewriting integration code is genuinely useful day-to-day.”
“Terminal-native and entirely engineer-focused. Zero relevance for creative workflows unless someone builds a GUI on top. Check back if a visual interface emerges.”
