RelayFlow — The Production-Grade Reliability Wrapper for Zapier That Stops 2am Outages From Costing You Clients
Zapier goes down, your client's order confirmation stops firing, and you find out at 8am via an angry email. RelayFlow wraps your existing Zaps with retry logic, failover to a backup Make.com scenario, and a real-time SLA dashboard — without migrating a single workflow. Sleep is once again an option.

Production Zapier users regularly report outages costing them client relationships, with no native retry or failover option beyond manually re-triggering failed Zaps after the fact.
What is it?
Production Zapier users have been screaming on Reddit for two years that outages cost them clients, but the only real answer is 'migrate to n8n' — a three-week project nobody wants to do mid-contract. RelayFlow sits in front of any Zapier webhook trigger, queues the event in a durable store, retries on failure, and can failover the payload to a backup Make.com or n8n webhook if Zapier stays down for more than 60 seconds. The SLA dashboard shows uptime per workflow, failure counts, and auto-sends a status email to clients before they notice. Fully buildable using Cloudflare Queues for durable event storage, Upstash for retry scheduling, and Zapier's existing webhook trigger surface — no Zapier API partnership required.
Why now?
Cloudflare Queues exited beta in late 2025 making durable webhook queuing trivially cheap for solo builders — this infrastructure gap no longer requires AWS SQS complexity or enterprise budget.
- ▸Durable event queue that intercepts Zapier webhook triggers and retries on failure up to 10 times
- ▸Failover routing that forwards the queued payload to a backup Make.com or n8n webhook after configurable timeout
- ▸Per-workflow SLA dashboard showing uptime percentage, failure count, and MTTR over 30 days
- ▸Proactive client status email sent automatically when a workflow fails — before the client notices
Target Audience
Zapier power users and automation agencies running production workflows (est. 15,000+ on r/zapier and Zapier community forums)
Example Use Case
An e-commerce agency has a Zap that fires Shopify order data to their client's ERP — during a Zapier outage the order payload lands in RelayFlow's queue, retries every 30 seconds for 10 minutes, then fails over to a backup Make.com scenario, and the agency gets a Slack alert instead of an angry client call.
User Stories
- ▸As an automation agency, I want my Zapier webhooks to retry automatically on failure, so that a Zapier outage does not break my client's production workflow.
- ▸As a freelancer managing client automations, I want a failover URL that receives my payload if Zapier is down, so that data is never lost during outages.
- ▸As an agency owner, I want my client to receive a proactive status email when their workflow fails, so that I look professional instead of reactive.
Done When
- ✓Queue ingest: done when user points a webhook at RelayFlow proxy URL and sees the event appear in dashboard within 3 seconds.
- ✓Retry logic: done when a simulated timeout causes the event to retry 3 times with 30-second backoff and all attempts appear in the log.
- ✓Failover: done when max retries are exhausted and the payload is forwarded to the configured backup URL within 5 seconds.
- ✓Status alert: done when a workflow failure triggers an email to the configured client address within 60 seconds of first failure.

Launch & Validation Plan
Search r/zapier for 'outage' and 'breaking' posts from the last 6 months, DM the top 20 commenters offering free beta access before writing code.
Customer Acquisition Strategy
First customer: reply directly to active r/zapier outage complaint threads with a personal DM offering free setup for 60 days. Ongoing: SEO targeting 'Zapier down 2024,' ProductHunt launch timed to the next major Zapier outage news cycle.
What's the competition?
Competition Level
Low
Similar Products
Zapier built-in retry (only 3 retries, no failover, no SLA visibility), Make.com (requires full migration), PagerDuty (monitors infra not workflow logic). Gap: no product provides Zapier-native event queuing and failover without migration.
Competitive Advantage
No product currently provides durable event queuing and failover for Zapier specifically without requiring full migration away from the platform.
Regulatory Risks
Low regulatory risk. Webhook payloads may contain PII — ToS must require customers to classify data and not route HIPAA-covered events through the queue.
What's the roadmap?
Feature Roadmap
V1 (launch): webhook proxy, queue, retry, failover, SLA dashboard. V2 (month 2-3): white-label status page, Slack alert integration, per-event payload inspector. V3 (month 4+): Make.com native source, SLA guarantee tiers, team seats.
Milestone Plan
Phase 1 (Week 1-2): Cloudflare Queue, ingest endpoint, retry consumer live. Phase 2 (Week 3-4): failover routing, SLA dashboard, Resend alerts, Stripe billing. Phase 3 (Month 2): 8 agencies running production workflows through RelayFlow.
How do you build it?
Tech Stack
Next.js, Cloudflare Queues, Upstash Redis, Supabase, Resend, Stripe — build with Cursor for queue logic, v0 for SLA dashboard
Suggested Frameworks
Cloudflare Workers, Upstash Redis, Hono
Time to Ship
3 weeks
Required Skills
Cloudflare Workers and Queues, Upstash Redis retry logic, Next.js, Supabase.
Resources
Cloudflare Queues docs, Upstash retry workflow docs, Zapier webhook docs.
MVP Scope
app/page.tsx (landing with outage stats hook), app/dashboard/page.tsx (workflow SLA list), app/api/ingest/[id]/route.ts (webhook receiver and queue push), app/api/status/route.ts (SLA metrics), workers/retry.ts (Cloudflare Queue consumer), lib/db/schema.ts (Workflow, Event, FailureLog tables), .env.example
Core User Journey
Sign up -> paste Zapier webhook URL -> get RelayFlow proxy URL -> update Shopify to point at proxy -> first queued event appears in dashboard -> upgrade to paid.
Architecture Pattern
External webhook fires to RelayFlow ingest endpoint -> Cloudflare Queue stores event -> Worker consumer forwards to Zapier -> on failure re-queues with backoff -> after max retries routes to failover URL -> Supabase logs all events -> Resend sends client alert.
Data Model
User has many MonitoredWorkflows. Workflow has many Events. Event has one FailureLog. Workflow has one FailoverConfig.
Integration Points
Cloudflare Queues for durable event storage, Upstash Redis for retry scheduling, Supabase for event logs and config, Resend for status alerts, Stripe for billing.
V1 Scope Boundaries
V1 excludes: Make.com as primary (failover target only), n8n native integration, mobile app, team collaboration, white-label status pages.
Success Definition
A paying agency runs a Shopify-to-ERP Zap through RelayFlow for 30 days, Zapier has one real outage, RelayFlow queues and retries successfully, and the agency never contacts support.
Challenges
The hardest problem is convincing agencies to add a new proxy layer in front of production workflows they are scared to touch — this is a trust and change-management problem, not a technical one. First 10 customers require hands-on white-glove onboarding.
Avoid These Pitfalls
Do not build a full workflow editor — the value is reliability, not features. Do not support every automation platform in V1 — Zapier only or you ship nothing. Finding the first 10 paying customers requires personal outreach to real Zapier outage victims, not cold traffic.
Security Requirements
Supabase Auth with magic link, RLS on Workflow and Event tables, ingest endpoint authenticated via rotating secret key, payloads stored encrypted at rest, rate limit 1,000 events/min per workspace.
Infrastructure Plan
Vercel for Next.js, Cloudflare Workers and Queues for event processing, Supabase for config and logs, Upstash Redis for retry state, Sentry for errors, GitHub Actions for CI.
Performance Targets
Ingest endpoint responds under 50ms, queue consumer processes events under 200ms, dashboard loads under 2s, 150 DAU at launch.
Go-Live Checklist
- ☐Security audit complete.
- ☐End-to-end failover flow tested.
- ☐Sentry error tracking live.
- ☐Cloudflare Queue monitoring set up.
- ☐Custom domain SSL configured.
- ☐Privacy policy and ToS published.
- ☐5 beta agencies with live workflows.
- ☐Rollback plan for queue consumer documented.

First Run Experience
On first run: a demo workflow is pre-loaded showing 3 sample events — one successful, one retried, one failed-over. User can immediately create their first monitored workflow by pasting any webhook URL. No manual config required: demo data renders without a real Zapier connection.
How to build it, step by step
1. Define Drizzle schema for MonitoredWorkflow, Event, FailureLog, FailoverConfig in lib/db/schema.ts. 2. Scaffold Next.js with Supabase Auth and Tailwind. 3. Build Cloudflare Queue and Worker consumer in workers/retry.ts with exponential backoff. 4. Create ingest endpoint in app/api/ingest/[id]/route.ts that pushes to queue and returns 200 immediately. 5. Build retry consumer that forwards payload to Zapier webhook URL and logs success or failure to Supabase. 6. Add failover logic that routes to backup URL after 3 consecutive failures. 7. Build SLA dashboard in app/dashboard with uptime percentage and failure count per workflow. 8. Wire Resend to send client alert email on first failure detection. 9. Add Stripe subscription billing gated behind workflow count limits. 10. Verify: simulate a Zapier webhook timeout, confirm event is queued, retried 3 times, failed over to backup URL, and dashboard shows the failure event.
