Best alternatives to SHIM in 2026
Every time your app calls OpenAI, Anthropic or Gemini, whatever your users typed — including emails, phone numbers, or card numbers they shouldn't have shared — goes straight to that provider. SHIM sits in between as a checkpoint: it catches and blanks out that sensitive information before the request leaves, without you having to change a line of your app's code. SHIM is a Python/FastAPI gateway, distributed as a Docker container, that transparently proxies traffic to OpenAI, Anthropic and Gemini. It detects and redacts PII (emails, phone numbers, credit cards, IBANs, national IDs, provider secrets), enforces rate limits (requests/tokens per minute), blocks repeat-loop request patterns, and tags every request with cost/usage attribution via an X-Shim-Tag header. The open-source Community Edition (Apache-2.0) needs no database and keeps state process-local; a paid Enterprise Edition (Elastic License 2.0) adds multi-tenancy, persistent audit logs, RBAC and budget controls.
