🛡️ Pre-LLM & Ticket Safety: How to sanitize openapi.yaml and swagger.json (servers, securitySchemes, examples) before pasting into ChatGPT, Claude, or Cursor to generate SDKs
Core capabilities built into OpenAPIShield
Unlike regex replacements that break JSON/YAML escaping or $ref component paths, our AST scanner redacts only sensitive scalar values inside examples, defaults, and headers.
Automatically anonymizes internal AWS Lambda ARNs, VPC Link IDs, and private Kubernetes service URLs inside vendor extension blocks.
Replaces real production tokens accidentally recorded by traffic-to-OpenAPI generators (Har2OpenAPI, Optic, Akita) with deterministic schema-valid dummy tokens.
Your unreleased API routes, internal microservice topology, and sample customer payloads never touch third-party SaaS doc portals.
Zero configuration, zero cloud server dependencies, instant execution.
See why merchants and prosumers switch from monthly subscriptions to our local buyout.

One-Off Emergency Unlock & Trial
Everything you need to know about privacy, local memory execution, and buyouts.
Drop your openapi.yaml or swagger.json into OpenAPIShield. It targets scalar values inside servers[], securitySchemes, and example blocks in local browser RAM while keeping all $ref component pointers and schema types 100% intact.
Tools that auto-generate OpenAPI specs from live network traffic embed actual Authorization headers, eyJ... JWTs, and session cookies directly into the example and default fields of your YAML/JSON file.
Yes. OpenAPIShield detects 12-digit AWS account numbers, internal VPC Link IDs, and Lambda invocation ARNs inside API Gateway extension fields and replaces them with clean placeholders.
Yes. All parsing and redaction run 100% inside your browser's local memory with zero network requests, allowing you to safely generate TypeScript/Python SDKs with LLMs.
SwaggerHub is a cloud collaboration platform that requires uploading your specification to external servers. OpenAPIShield is a zero-egress client-side appliance ($19 one-time buyout) built specifically for pre-commit, pre-LLM, and pre-partner sanitization.
