    Cloudflare Introduces Email Service to Compete with Amazon SES, Resend, and SendGrid

    Cloudflare announced a private preview of its Email Service during Birthday Week, enabling developers to send and receive emails directly from Workers without API keys. The globally managed service automatically configures SPF, DKIM, and DMARC for improved deliverability, supports both REST APIs and SMTP, and integrates with Workers AI for routing and parsing incoming emails. Unlike regional services like Amazon SES, Cloudflare offers a single global endpoint. The beta launches in November with message-based pricing and requires a paid Workers subscription.

    A PostgREST-Compatible Data API, Now on Neon

    Neon launched a PostgREST-compatible Data API that allows querying Postgres databases directly over HTTPS. Built as a Rust re-implementation of PostgREST integrated into Neon's proxy fleet, it offers improved resource efficiency, multi-tenant architecture, and automatic scaling across thousands of databases. The API provides dedicated endpoints for each database branch, supports scale-to-zero compute while maintaining constant availability, and integrates with Neon Auth or external JWT providers. Designed particularly for AI agent platforms, it eliminates the need for Postgres client libraries by using standard HTTP requests with JWT authentication and Row-Level Security.

    3.5x Faster (I bullied Cloudflare into fixing their performance)

    Cloudflare improved Workers performance by up to 3.5x after community benchmarks revealed gaps compared to Vercel. The team spent a week fixing scheduling algorithms, V8 garbage collection tuning, stream adapters, and JSON parsing. They also contributed upstream fixes to Node.js and V8 that benefit the entire ecosystem. Key improvements include better cold start handling, reduced memory allocations in OpenNext, and optimized trigonometry functions.
