FW Delta vs. Zapier
Zapier is convenient — but has fundamental limits: 30-second timeout, 1KB code limit, polling instead of events. FW Delta: unlimited. And 36% cheaper over 3 years.
The 30-Second Time Bomb
Zapier kills every task after 30 seconds. Batch operations, reports, complex transformations — all impossible. FW Delta: unlimited execution time, configurable timeouts, no artificial limits.

The 5 Critical Zapier Limits
Why Zapier falls short for mission-critical workflows
30-Second Task Timeout
CriticalEvery task running longer than 30 seconds gets killed. No exceptions, no workarounds.
Batch imports of 100+ records, complex report aggregations, API calls to slow endpoints — everything breaks.
Unlimited execution time. 5-hour tasks, batch processing with 100K+ records, no problem.
1KB Custom Code Limit
CriticalCode steps are limited to 1KB. That's roughly 20-30 lines of code — without dependencies.
Even a simple data validation or transformation exceeds the limit. Complex business logic is impossible.
Full JavaScript/TypeScript/Python support. Complex logic, external libraries, no limits.
Polling Instead of Event-Driven
HighMany triggers rely on polling (checking every 1-15 minutes), not real events.
When a CRM update happens, it takes up to 15 minutes before the automation kicks in. Real-time response impossible.
Event-driven architecture. <100ms response on webhook events. True real-time.
No Database Transactions
HighZapier has no concept of atomic operations. When a Zap partially fails, data is left in an intermediate state.
Order gets created in CRM, but fulfillment fails. Manual cleanup required. At 1,000+ orders/day: chaos.
Full ACID transactions. All or nothing. Data integrity is guaranteed.
Vendor Lock-in & Price Explosion
HighZaps are proprietary and non-exportable. Every price increase you either accept or rebuild everything.
Zapier has raised prices twice in the past 3 years. Migrating 100+ Zaps takes months.
Your code, your infrastructure. Git-based, documented, migratable anytime. Zero dependency.

120 Zapier Workflows Migrated
E-Commerce Brand (D2C) · Online Retail · 45-80 Employees
Challenge
120 active Zapier workflows. Order sync: Shopify → HubSpot → Slack → Google Sheets → Warehouse Management. With 30s timeout: 15-20% of order syncs fail daily. Zapier bill: €1,050/mo (incl. premium apps).
Solution
Migration to FW Delta custom workflows. Batch orders (up to 1,000) synced in a single task. Full error logging & retry logic. Event-driven instead of polling.

When Zapier, When FW Delta?
Honest assessment — Zapier isn't always the wrong choice
Zapier makes sense when…
- Non-technical team without developer resources
- Simple 1:1 integrations (Slack → Sheet, Mail → CRM)
- Under 10 active workflows, low volume
- Quick proof-of-concepts (hours, not weeks)
- Workflows under 30 seconds, simple transformations
- OpEx preferred over capital expenditure
FW Delta makes sense when…
- High task volume (50K+/mo or rapidly growing)
- Complex business logic (validation, transformations, state)
- Legacy systems, proprietary APIs, SOAP/EDI
- Data sovereignty (GDPR, German hosting required)
- Tasks >30 seconds (batch imports, reports, ML pipelines)
- Real-time response required (<100ms latency)
Migration Roadmap
4 phases, 8-10 weeks. Zero workflow downtime.
Inventory all Zapier workflows, document dependencies, identify critical paths, define performance requirements.
Set up workflow engine, configure database, integrate API authentications, implement logging & monitoring.
Migrate critical workflows first. Parallel operation (Zapier + custom). Error handling more robust than Zapier. Performance tests.
Gradual switchover. 24/7 monitoring. Zapier workflows as fallback. Downgrade account once stable.
Frequently Asked Questions
How long does migration from Zapier to FW Delta take?
8-10 weeks for a typical enterprise stack with 50-150 workflows. We migrate in parallel so there's zero workflow downtime.
What happens to my existing Zapier integrations?
Every Zapier integration gets re-implemented as a custom workflow — often more robust and faster than the original. Zapier's 6,000+ app integrations are replaced by direct API connections.
Do I need developers to maintain the workflows?
No. FW Delta delivers complete documentation and a monitoring dashboard. Changes to business logic can be implemented on demand. Hosting runs automatically.
What does maintenance cost after implementation?
€60/mo for hosting on Hetzner (Germany). No task limits, no overage fees, no hidden costs. Code ownership stays with you.
Can I migrate individual workflows incrementally?
Yes. We actually recommend a phased approach: critical workflows first, then lower priorities. Zapier and custom run in parallel until you're confident.
What about Zapier features like Paths and Filters?
FW Delta replaces these with real programming constructs: if/else, switch/case, loops, state machines. Everything possible in code — without the 1KB limit or 30s timeout.
Break Free from Zapier's Limits
