Show & Tell: AI Router Proxy v1.0 — Self-hosted multi-backend proxy for Claude Code

[eroslifestyle]

What is this?

A self-hosted proxy that sits in front of Claude Code and lets you switch
between Claude (Anthropic) and MiniMax instantly — with automatic
failover, context compression, and a smart "interactive" mode that routes
trivial tasks to the cheaper backend and verifies critical ones with Claude.

License: MIT
Language: Python 3.11+ (aiohttp)
Stack: 3 systemd services + 1 proxy = 5 ports

Why I built it

Claude Code pointed at Anthropic is great — but:

• Subscription blip = workflow stops
• Some tasks (renames, summaries, boilerplate) are overkill for Opus
• I wanted a single endpoint (http://127.0.0.1:8787) that does the routing
  for me, not 5 different API configs to manage

4 routing modes

Mode	Behaviour	When to use
anthropic	Pure Claude passthrough	Max quality
minimax	Pure MiniMax passthrough	Max savings
mixed	Anthropic primary → MiniMax fallback on 401/429/5xx	Service continuity
interactive	T0/T1 → MiniMax, T2 (security/audit/critical) → MiniMax + Opus verify	Smart savings

Quick start

git clone https://github.com/eroslifestyle/ai-router-switch
cd ai-router-switch
# See docs/QUICKSTART.md and the bilingual manuals in docs/

Triple-defense resilience

• systemd with Restart=always on all 3 services
• Cron watchdog (ai-stack-guard.sh) every 60s — falls back to nohup if systemd lags
• PreToolUse hook blocks kill / systemctl stop / disable on the 3 protected services

What I'd love feedback on

1. Mode design — is "interactive" worth the complexity, or would 2 modes suffice?
2. Fallback set — I included 401/403 in FALLBACK_STATUSES (auth/billing = retryable). Reasonable?
3. Naming — "AI Router Proxy" or "AI Router Switch"? Both show up in the docs (decision: proxy).
4. Show HN — is this interesting enough to submit to HN? Or too niche?
