A middleware shim specifically for no-code platforms like Bubble, Webflow, and Glide that preserves raw webhook bodies and handles HMAC verification so builders never touch crypto code
Every no-code developer integrating Razorpay, Stripe, or Paddle hits this exact wall and currently has no clean solution
Built for Bubble users validating payment webhooks.
No-code platforms strip or re-encode request bodies before workflows run, making standard HMAC verification impossible without a dedicated proxy layer built for that constraint

Why this is a gap
Surfaced from a high-intensity complaint with clear willingness to pay and a specific, reachable audience.
The market
Bubble users validating payment webhooks (e.g., from Razorpay) need HMAC signature verification with raw request body access. No search volume data, but this is a specific technical need within the Bubble no-code platform community.
Competition & the opening
Moderately crowded (7/10): Svix, Hookdeck, ngrok, AWS API Gateway, Cloudflare Workers, and the Standard Webhooks specification all provide webhook body preservation and HMAC verification patterns. For Bubble users specifically, the gap is unclear — most reach for external webhook gateways or Workers.
What's hard to build
Bubble's API limitations and sandboxed execution model constrain how raw request bodies can be captured and passed to workflows. Integrating tightly with Bubble's authentication and plugin ecosystem requires navigating undocumented APIs or relying on Bubble's official plugin system, which is restrictive.
Why now
Low-code platforms (Bubble, Zapier, n8n) lack raw body preservation; Svix and Hookdeck are overkill for one-off webhook HMAC validation; a minimal middleware fills the gap.
