sed -E 's/^([A-Z0-9_]+_?(KEY|SECRET|TOKEN|URL|PASS)[A-Z0-9_]*=).*/\1"[REDACTED_ENV_SECRET]"/' .env.production > .env.example⚠️ Why Naive CLI / Regex Fails: Naive sed regexes on .env.production wipe entire DATABASE_URL connection strings (destroying the host/port/schema structure needed to debug Prisma/Drizzle pooling errors), break multi-line PEM private keys (GOOGLE_PRIVATE_KEY="-----BEGIN...\n..."), and miss NEXT_PUBLIC_ vs server-only misconfigurations.
🛡️ Pre-LLM & Ticket Safety: How to sanitize a Micro-SaaS .env.production, vercel.json, or Prisma schema config before pasting into Cursor, ChatGPT, or Claude or sharing in a GitHub Issue
Core capabilities built into SaaSEnvShield
Recognizes sk_live_*, rk_live_*, whsec_*, sbp_*, eyJ* service_role JWTs, sk-proj-*, and re_* tokens, replacing secret payloads while preserving prefix type hints.
Redacts passwords and tenant IDs inside postgresql:// and redis:// URIs while preserving pgbouncer=true, connection_limit, and sslmode query parameters.
Safely masks multi-line escaped RSA/PKCS8 private keys (\n) and flags server secrets accidentally prefixed with NEXT_PUBLIC_ or VITE_.
Generate GH013-clean .env.example templates and safely debug full-stack deployment errors in Claude, ChatGPT, or Cursor with zero cloud upload.
Zero configuration, zero cloud server dependencies, instant execution.
Paste Next.js/Remix .env.production files, Supabase/Clerk/Stripe environment blocks, or vercel.json env objects directly into browser RAM.
Dotenv-aware parsers mask sk_live_*, whsec_*, Supabase service_role JWTs, Resend/OpenAI keys, and PostgreSQL DSN passwords while keeping variable names intact.

Everything you need to know about privacy, local memory execution, and buyouts.
When debugging Next.js, Supabase, Stripe, or Prisma deployment errors, developers often copy-paste their .env.production or vercel.json file into an LLM prompt. That single paste transmits live Stripe sk_live_* keys, Supabase service_role JWTs (which bypass Row Level Security), and production database passwords to external servers.
A naive sed 's/=.*/=REDACTED/' wipes out the entire value of DATABASE_URL and NEXT_PUBLIC_APP_URL—hiding whether you are missing ?pgbouncer=true&connection_limit=1 or pointing to the wrong port—and corrupts multi-line PEM keys.
GitHub Push Protection (GH013) and Gitleaks scan for Stripe sk_live_*, whsec_*, OpenAI sk-proj-*, and JWT patterns. SaaSEnvShield deterministically replaces the secret entropy while keeping structural prefixes and URL parameters intact.
Yes. It preserves variable names so you can immediately spot if a sensitive key like SUPABASE_SERVICE_ROLE_KEY or STRIPE_SECRET_KEY was mistakenly exposed to the frontend bundle.
Never. All dotenv parsing, DSN password masking, and Canvas entropy visualization execute 100% locally inside your browser RAM with zero network egress.
