Gateway Migration Kit
A guided migration tool that helps an AI engineering team move from in-process provider keys to a network-proxy architecture in a weekend, with pre-built OpenAI/Anthropic/Gemini proxies, a verification harness, and a rollback plan.
Senior backend engineers and platform owners tasked with reducing the blast radius of AI credentials after a security review
- Pre-built reference proxies for OpenAI, Anthropic, and Gemini with token scoping, rotation, and policy hooks out of the box
- Codemod that rewrites common SDK call sites to talk to the proxy instead of the provider directly, language by language
- Verifier that runs the same malicious-dependency payload against the old and new architecture and produces a side-by-side report for the security review
- Rollback playbook plus a 'dual-run' mode that runs both architectures in parallel for a week so the migration is reversible
The Dev.to article makes a clear architectural argument but offers no migration path; teams that get the message have nowhere to go but a months-long internal project.
Active discussion of LLM API key blast-radius and gateway/proxy patterns; multiple 2026 comparison articles (LiteLLM, Portkey, Cloudflare, Kong, Helicone, Vercel, OpenRouter, Bifrost, CometAPI) confirm real spend and production migration interest; Dev.to source post has only 26 reactions, suggesting modest reach.AI Gateway Comparison: LiteLLM vs Portkey vs Cloudflare vs Kong for LLM Routing ↗Best LLM Gateway 2026: 9 Tools Ranked & Tested | TECHSY ↗
Market is already crowded: 9+ competing gateways including open-source LiteLLM, voidllm, Mirrowel/LLM-API-Key-Proxy, plus managed Portkey, Cloudflare, Kong, Vercel, Helicone, OpenRouter, Bifrost; the 'migration path' wedge is thin because these vendors publish their own migration docs.AI Gateway Comparison: LiteLLM vs Portkey vs Cloudflare vs Kong ↗Mirrowel/LLM-API-Key-Proxy - GitHub ↗GitHub - voidmind-io/voidllm ↗
LiteLLM is MIT-licensed and free; Cloudflare/Vercel gateways ship at near-zero setup cost; Portkey and Kong monetize via managed/enterprise tiers; a one-shot 'migration kit' competes with free vendor docs and faces commoditization pressure, capping willingness to pay.LiteLLM Proxy Production Tutorial: LLM Gateway in 2026 ↗OpenRouter vs LiteLLM vs Portkey: Best LLM Gateway in 2026 ↗
LLM credential blast-radius concerns only intensify as enterprise AI spend grows; proxy/gateway architecture is becoming a standard control plane and security reviews are recurring, giving durable demand.AI Security Gateway: How Proxying LLM and MCP Calls Enables Security ↗
Pre-built proxies are essentially commodity reference implementations against OpenAI/Anthropic/Gemini APIs; the harder parts are the verification harness (parity tests across providers) and a safe rollback plan, both non-trivial but achievable for a senior platform engineer.
