Reviewer scorecard
“The free tier is absurdly generous and the cold starts are essentially zero. For APIs, middleware, and edge logic, nothing else gives you this performance at this price.”
“The API is clean, the React Email integration is brilliant, and deliverability is excellent. Replaced SendGrid in 20 minutes and never looked back.”
“The Worker runtime has limitations — no Node.js stdlib, size limits, CPU time limits. Know the constraints. But for what it does well, it's unbeatable.”
“Young company with a smaller scale than SendGrid or Postmark. But the developer experience is so much better that it's worth the risk for startups. Monitor deliverability closely.”
“Cloudflare is building the programmable internet. Workers + D1 + R2 + AI = a complete platform that runs at the edge. They're quietly becoming the default infrastructure layer.”
“Building beautiful transactional emails used to be painful. React Email components make it feel like building a web page. Game changer for my client projects.”
