Cloudflare's pricing page is a ladder of four plans. Free is aimed at personal and hobby projects and carries fast DNS, unmetered DDoS protection, the CDN and Universal SSL at $0. Pro is $20 per month billed annually or $25 month-to-month for professional websites, and it is where the full web application firewall, lossless image optimization and accelerated mobile pages arrive. Business is $200 annually or $250 monthly and adds a 100% uptime SLA with service credits, plus PCI DSS 4.0 compliance for stores. Contract is the enterprise tier, billed annually, with 10x or 25x uptime credits depending on package. On the compute side, Workers are free for 100,000 requests a day with 10ms of CPU time per request, then $0.30 per million requests and $0.02 per million CPU milliseconds.
TL;DR
These two are not rivals for the same budget — they solve different halves of the same app. Cloudflare sells the network in front: Free at $0 with unmetered DDoS, CDN and Universal SSL, Pro at $20/mo billed annually ($25 monthly) adding image optimization and the full WAF, Business at $200 annually. Supabase sells the data behind: Free with a 500MB Postgres database, 50,000 monthly active users and 5GB egress, Pro at $25/mo with 8GB of disk per project and $10 of compute credit, Team at $599/mo for SOC 2 and ISO 27001. If you only need one of them, buy the one whose absence is blocking you; most teams end up running both, Supabase for the data and Cloudflare for the traffic.
Supabase sells a Postgres database with the surrounding products already attached. Free runs 500MB of data on shared CPU, 50,000 monthly active users, 5GB of egress, 1GB of file storage, two active projects and unlimited API requests, and the plan pauses a project after one week of inactivity. Pro is $25 per month per organization: 8GB of disk per project then $0.125 per GB, $10 of compute credit covering a Micro instance, 100,000 monthly active users then $0.00325 each, 250GB of egress then $0.09 per GB, email support and daily backups kept for seven days. Team is $599/mo with SOC 2, ISO 27001, dashboard SSO, priority support and 14-day backups; Enterprise is quoted and can run on AWS PrivateLink.
Read the two catalogues side by side and the overlap is almost nil: Cloudflare has no database, Supabase has no CDN or firewall for the public internet. The real question is which gap you feel first. An app with a database exposed directly to the web needs Cloudflare in front of Supabase; a static site with a form needs Cloudflare alone; a back end behind an existing authenticated API may need Supabase alone. Paying for both is normal, and at $20 plus $25 a month it is cheaper than either platform's Business or Team tier.
| Feature | Cloudflare | Supabase |
|---|---|---|
| Free tier | DNS, unmetered DDoS, CDN, Universal SSL at $0 | 500MB Postgres, 50,000 MAU, 5GB egress at $0 |
| Entry paid plan | Pro $20/mo billed annually, $25 monthly | Pro $25/mo: 8GB disk per project, $10 compute credit |
| Next tier | Business $200/mo billed annually, $250 monthly | Team $599/mo with SOC 2, ISO 27001 and SSO |
| Data layer | None — no relational database or row-level storage | Postgres included, unlimited API requests on every plan |
| Edge protection | WAF, DDoS mitigation and TLS on the plan itself | None included; needs a proxy or CDN in front |
| Compute billing | Workers: 100k requests/day free, then $0.30 per million | Compute billed per project; $10 credit covers one Micro instance |
| Inactivity | Free plan has no expiry condition on sites | Free projects pause after one week, two projects maximum |
| Top tier | Contract, billed annually, 10x or 25x uptime credits | Enterprise with 24x7 support and AWS PrivateLink |
Pick Cloudflare if
When the site is slow, under attack, or served over plain HTTP by accident, Cloudflare fixes it in one change of nameserver. Start free, move to Pro at $20/mo billed annually when the WAF and image optimization matter, and let Workers handle small logic at $0.30 per million requests. It will never store your rows.
Pick Supabase if
When you need accounts, records, files and rules about who may read them, Supabase hands you a Postgres database with the API already generated. The free tier covers a prototype at 500MB and 50,000 monthly active users, and $25/mo on Pro is a predictable floor for a live app — provided something else handles the public edge.

No. Cloudflare terminates and protects traffic; Supabase stores data and serves an API. They overlap only in the small amount of edge logic Workers can run, and even then Supabase is usually the back end those Workers call.
Both have usable free tiers: Cloudflare covers DNS, CDN, TLS and unmetered DDoS at $0, and Supabase runs 500MB of Postgres with 50,000 monthly active users at $0. Paid, they are $20 and $25 a month respectively, so the pair costs less than either vendor's next tier.
Supabase secures data with row-level security and restricts database connections, but it does not run a CDN, absorb DDoS traffic or give you a WAF for public endpoints. Those functions are exactly what Cloudflare's plans provide.
It pauses after one week of inactivity, and an organization is limited to two active projects. Paid plans are never paused, which is the practical reason to move to Pro once something real depends on the database.
The free allowance is 100,000 requests per day with 10ms of CPU time per request. Past that, requests bill at $0.30 per million and CPU time at $0.02 per million CPU milliseconds, both shown in the pricing page's component table.
