# Zalapier > Zalapier is the bulletproof webhook buffer and Zapier alternative for webhooks. It catches every incoming webhook, persists it to Postgres before any delivery attempt, and forwards it to one or many destinations with exponential-backoff retries — so server restarts, deployments, and crashes never drop a payment or automation event. ## Summary Zalapier sits between webhook senders (Stripe, Polar, GitHub, Shopify, Twilio, etc.) and your fragile destinations (n8n, Make, Pipedream, your API). It durably stores each payload, fans out to multiple destinations, retries on failure with exponential backoff, and lets you edit-and-replay broken payloads from a built-in sandbox. ## Pricing - **Free** — 1 endpoint, 1 destination, 1,000 webhooks/month, 1-day retention - **Pro** — $29/month flat. 2 endpoints, 5 destinations, 100,000 webhooks/month, 7-day retention - **Ultra** — $99/month flat. Unlimited endpoints + destinations, 1,000,000 webhooks/month, 30-day retention All plans are flat-rate with no per-task fees. At 50,000 webhooks/month Zapier costs ~$599; Zalapier Pro costs $29 — about 20× cheaper. ## Key features - Persistent Postgres-backed buffer (never drop a payload) - Exponential-backoff retries: 1m → 5m → 15m → 1h → 4h - Edit & replay sandbox for failed payloads - Fan-out routing to unlimited destinations - Outbound HMAC signing via X-Zalapier-Signature header - Inbound HMAC verification for Stripe, Polar, etc. - Real-time delivery dashboard - Full payload search and filter by status ## How it works 1. Sign up free at https://zalapier.com and create an endpoint 2. You get a unique webhook URL: https://zalapier.com/api/in/{your-slug} 3. Point Stripe, Polar, GitHub, etc. at that URL 4. Add one or more destinations (n8n, Slack, your API) 5. Zalapier persists every payload, fans out to destinations, and retries on failure ## Common questions - **Best Zapier alternative for webhooks?** Yes — flat $29/mo vs Zapier's per-task pricing - **Replaces n8n / Make?** Sits in front of them as a buffer; never lose a payload during their downtime - **HMAC support?** Yes, both inbound verification and outbound signing - **Retention?** 1d / 7d / 30d depending on plan; status preserved indefinitely ## Comparisons - Zalapier vs Zapier: https://zalapier.com/compare/zapier - Zalapier vs Hookdeck: https://zalapier.com/compare/hookdeck - Zalapier vs Svix: https://zalapier.com/compare/svix ## Use cases - Stripe webhook buffer: https://zalapier.com/use-cases/stripe-webhooks - Polar webhook buffer: https://zalapier.com/use-cases/polar-webhooks - n8n webhook buffer: https://zalapier.com/use-cases/n8n-webhooks ## Blog (webhook reliability guides) - Why Stripe webhooks silently fail: https://zalapier.com/blog/stripe-webhook-failures - Webhook retry strategy that works: https://zalapier.com/blog/webhook-retry-strategy - Blog index: https://zalapier.com/blog ## Links - Home: https://zalapier.com - Pricing (full HTML page): https://zalapier.com/pricing - How it works: https://zalapier.com/#how-it-works - Features: https://zalapier.com/#features - FAQ: https://zalapier.com/#faq - Pricing for AI agents (machine-readable): https://zalapier.com/pricing.md - Sitemap: https://zalapier.com/sitemap.xml - Contact: hello@zalapier.com
