HookSieve
The Edge Webhook Firewall. Cut 75% of Zapier & LLM costs.
HookSieve is a zero-code edge middleware that verifies, deduplicates, and filters out spam or unpaid webhooks before they trigger expensive downstream Zapier/Make workflows and LLM agent tokens. Cut up to 75% of automation bills and save 80% on AI context tokens with Cloudflare-native sub-10ms latency.
👋 Hey Product Hunt community!
I'm Rex, maker of HookSieve.
Like many of you running e-commerce stores or building AI agents, I was shocked by my monthly Zapier & Make.com invoices. Why? Because Shopify and Stripe flood your endpoints with thousands of "abandoned checkouts", "pending orders", and duplicate webhook retries.
Every single useless ping triggered a full Zapier task and chewed through expensive LLM tokens—costing hundreds of dollars for events that resulted in $0 revenue.
I built HookSieve to fix this at the network edge:
🛡️ Cryptographic Verification: Automatically verifies HMAC signatures for Shopify, Stripe & GitHub.
⚡ Zero-Code Condition Filter: Drop unpaid or irrelevant webhooks before they reach Zapier/Make.
🌪️ Retry Storm Dedup: 60s sliding window deduplication to eliminate duplicate webhook bursts.
✂️ 80% AI Token Pruning: Strips bloated JSON payloads down to essential fields before hitting your AI Agent.
🪦 Dead Letter Queue (DLQ): Captures downstream 5xx errors with 1-click replay.
We've deployed HookSieve globally on Cloudflare Workers (sub-10ms latency).
🎁 Special PH Offer: HookSieve has a generous Forever Free tier (5,000 events/mo), and everyone who signs up today gets an extra 14-day Pro Trial with unlimited relays & AI Token pruning!
I'd love to hear your thoughts, feedback, and what integrations you'd like us to add next! 🚀
