Frequently Asked Questions

Clodo Framework uses a pay-as-you-go model through Cloudflare:

• Compute: $0.00001667 per request (first 100M/month free)
• Storage (D1): Included (SQLite database)
• KV Storage: $0.50/million operations
• R2 Object Storage: $0.015/GB (first 10GB free)

Typical enterprise app (1M requests/month): $20-50/month infrastructure

Compare to: Lambda ($200-300/month) + RDS ($50-100/month) + S3 ($5-20/month) = $255-420/month

Savings: 80-90% compared to traditional serverless

Clodo Framework is open-source and free. We offer optional commercial support tiers:

• Community Support: GitHub Discussions (free)
• Priority Support: Email + Slack (contact sales)
• Enterprise Support: Dedicated engineer (contact sales)

You only pay for Cloudflare's infrastructure, not the framework itself.

No. You only pay Cloudflare for what you use:

• ✅ Compute requests
• ✅ Data storage (D1, KV, R2)
• ✅ Analytics
• ❌ No platform fees
• ❌ No seat licenses
• ❌ No support fees (unless you opt in)

You control costs by optimizing your code and usage patterns.

Yes, but predictably and efficiently:

• Linear pricing: 2x traffic = 2x cost
• No overprovisioning: Pay only for actual requests
• Free tier covers: 100M requests/month (enough for 1M users with average usage)
• Rate limiting: Built-in, no surprise costs

A service with 1B requests/month costs ~$200, not $20,000 like traditional servers.

The Pre-Flight Checker is Clodo's deployment validation system:

• Before deployment: Validates all worker rules, environment variables, database connections
• Prevents crashes: Catches errors before they hit production
• Reduces downtime: Failed deployments never go live
• Enterprise-ready: Integrates with CI/CD pipelines

Think of it as your deployment insurance policy.

Learn more about deployment and the Pre-Flight Checker in our deployment guide.

Yes, multi-tenant is built-in, not an afterthought:

• Tenant isolation: Data automatically separated by tenant
• Namespace management: Automatic routing by tenant ID
• Database per tenant or shared: You choose the architecture
• Cost per tenant: Transparent, automatic billing if needed

Clodo was designed from day 1 for SaaS multi-tenant platforms.

See our case studies for examples of multi-tenant healthcare platforms and fintech payment systems.

Clodo currently supports:

• ✅ JavaScript/TypeScript (primary, full support)
• ✅ Python (via community packages)
• ✅ Rust (via WebAssembly)
• 🔄 Go, Java: Coming soon

Cloudflare Workers natively supports JavaScript/TypeScript with excellent DX.

Yes, Clodo excels at real-time:

• ✅ WebSockets: Supported via Durable Objects
• ✅ Real-time messaging: Low-latency global pub/sub
• ✅ Chat applications: Built-in for multi-user sync
• ✅ Live dashboards: Server-Sent Events (SSE)
• ✅ Collaboration tools: CRDT support available

Edge location means <10ms latency for real-time features.

Compare Clodo's real-time capabilities with traditional serverless in our Workers vs Lambda comparison.

Extremely fast:

• Initial setup: 5 minutes
• First deployment: 2-3 minutes
• Subsequent deploys: 10-30 seconds
• Zero downtime: Blue-green deployments automatic
• Rollback: 1 click, instant

Compare to: Traditional server (hours), Lambda (minutes), Clodo (seconds).

Cloudflare provides:

• ✅ 99.99% SLA for Enterprise customers
• ✅ 200+ data centers worldwide (automatic failover)
• ✅ DDoS protection included
• ✅ Automatic scaling: No manual intervention needed
• ✅ Zero cold starts: Always ready to serve

Your app is as reliable as Cloudflare's global infrastructure.

Yes, full CI/CD support:

• ✅ GitHub Actions: Deploy on push
• ✅ GitLab CI: Full integration
• ✅ CircleCI: Pre-flight validation
• ✅ Jenkins: Custom webhook support
• ✅ Environment promotion: Dev → Staging → Production

Pre-Flight Checker integrates directly into your CI/CD to prevent bad deployments.

Comprehensive monitoring built-in:

• Real-time logs: All requests/errors in Cloudflare dashboard
• Metrics: CPU, memory, errors, latency
• Analytics: Page views, geographic distribution, browser stats
• Alerts: Set thresholds for errors, latency
• Integrations: DataDog, New Relic, Grafana

No separate monitoring service needed.

Clodo on Cloudflare Workers has different limits depending on usage:

• CPU time: 30 seconds for Workers, up to 15 minutes for Durable Objects
• Memory: 128MB standard, up to 512MB available
• Request timeout: 30 seconds default
• File size: 25MB max upload size

Good for: API requests, web scraping, data processing

Not ideal for: Video encoding, large ML models (15+ seconds)

No cold starts with Clodo on Cloudflare Workers:

• ✅ ~0ms cold start: Code is pre-compiled at edge
• ✅ Always hot: Replicated to 200+ locations globally
• ✅ Instant response: No initialization delay
• ✅ Perfect for: P99 latency matters (customer-facing apps)

Lambda typically has 500ms-1000ms cold starts. Not an issue with Clodo.

Full security control built-in:

• ✅ CORS handling: Simple declarative syntax
• ✅ Security headers: CSP, X-Frame-Options, HSTS
• ✅ JWT validation: Built-in middleware
• ✅ Rate limiting: Per-tenant or per-IP
• ✅ WAF rules: Cloudflare WAF included

Security-first architecture by default.

Learn more about security features in our documentation.

Yes, multiple options:

• ✅ D1 (SQLite): Built-in, recommended
• ✅ PostgreSQL: Via Neon, Supabase
• ✅ MySQL: Via PlanetScale
• ✅ MongoDB: Via Atlas
• ✅ Custom APIs: HTTP calls to any service

Best practice: Use D1 for 90% of cases, external DB only if needed.

Check our code examples for database integration patterns.

Multiple options for file handling:

• ✅ R2 Object Storage: Store files permanently (recommended)
• ✅ Base64 encoding: Small files in D1 database
• ✅ Multipart form data: Full HTTP upload support
• ✅ Signed URLs: Direct browser-to-R2 uploads
• ✅ Size limits: Up to 25MB per request

R2 is cheapest option for large-scale file storage ($0.015/GB).

Flexible architecture:

• ✅ Standard Web APIs: Most code runs anywhere
• ⚠️ Cloudflare-specific: Durable Objects, D1, R2 (but documented)
• ✅ Migration path: Can move to other platforms if needed
• ✅ Open source: You own your code, not locked in

Not as locked-in as AWS Lambda, not as portable as plain Node.js. Balanced approach.
