| Attribute | Cloudflare | Convex | Firebase |
|---|---|---|---|
| Plans | FreeOur pick Free Almost every small business website. | Free and Starter Free, then pay as you go Side projects and small teams getting started. | SparkOur pick Free Early projects and apps with a small audience. |
Pro $20/mo billed yearly, or $25 monthly Professional sites that want faster images and support tickets. | ProfessionalOur pick $25/developer/mo Products with real users. | Blaze Pay as you go, no monthly fee Anything that might grow past the free quotas. | |
Workers Paid From $5/mo plus usage Builders hosting apps on Cloudflare. | Business and Enterprise From $2,500/mo Larger companies with compliance and scale needs. | ||
Business $200/mo billed yearly, or $250 monthly Online businesses that need an uptime guarantee. | |||
Enterprise Custom Mission-critical sites and large companies. | |||
| Which plan to pick | Put your site on the free plan. It covers speed, SSL and security for most small businesses. If you host an app on Workers, the $5 a month Workers Paid plan lifts the limits. Pro and Business only make sense when you need their image tools, support or uptime guarantee. | Start on Free. Move to Professional when you launch, mainly for daily backups and the bigger limits. Business is a big jump aimed at teams of 50 or more, so most readers will never need it. | Spark is enough until real users arrive. Move to Blaze when you need Cloud Functions or you're close to a quota, and set a budget alert the moment you do. There's no middle tier, so your bill goes straight from nothing to usage based. |
