Cloudflare Workers Free Edge Tier: 100K Requests Daily
Cloudflare announced that Cloudflare Workers — its edge serverless platform that runs JavaScript in 300+ data centers — offers a free tier with 100,000 requests per day. The free plan also includes Workers KV (100K reads, 1K writes/day), R2 object storage (10 GB free with zero egress fees), D1 database quotas (5M rows read, 100K writes/day), and Durable Objects for stateful edge compute. The article highlights fast cold-starts (0 ms) and compares Workers to Lambda on region count and latency. Deployment examples (npm create cloudflare@latest; npx wrangler deploy) and a small code snippet are provided for developers.
Cloudflare expanding accessible, low-latency edge compute and storage with a permanent free tier lowers operational cost and latency for developer workloads; this can enable adtech and martech teams to run edge personalization, measurement, or lightweight logic with reduced egress costs, making it moderately relevant infrastructure news.

Cloudflare for Developers: strengths, trade-offs, and usage
A technical walkthrough and practical guide to using Cloudflare as a developer platform. The article describes Cloudflare as a programmable network offering a generous free tier (TLS, global CDN, DNS, DDoS protection) plus an edge compute and storage platform (Workers, Pages, R2, KV, D1, Durable Objects). It highlights major advantages—instant startup via V8 isolates, no-egress R2 storage, and easy Git-connected Pages—and production caveats such as Workers not being full Node.js, bounded CPU per request, less-mature data products, and aggressive default caching/WAF behavior. The piece includes deployment examples using the Wrangler CLI and guidance on when to use Cloudflare versus a traditional server or other hosting providers.
Serverless Blog on Cloudflare Workers with KV and R2
A developer describes building 1001020, a serverless blog and AI gallery that runs entirely on Cloudflare edge infrastructure. The public site is implemented with Cloudflare Workers for routing and rendering, Cloudflare KV for article and site metadata, and Cloudflare R2 for managed image storage and a browsable gallery. The post explains the architecture, storage tradeoffs (KV as a simple key-value content store), image management via R2, and built-in SEO features such as sitemap and robots.txt. The author frames the system as a compact CMS-like publishing stack that avoids a conventional backend while supporting admin operations, sitemaps, and image cleanup workflows.
How an AI SaaS Was Built on the Edge for
A Dev.to case study describes building Propoza, an AI-powered proposal generator for Brazilian freelancers, using an edge-first, serverless stack to minimize infrastructure costs during validation. The team ran the backend on Cloudflare Workers, used Cloudflare D1 for a distributed SQLite database, Cloudflare Pages for the frontend, and an AI Gateway to proxy and cache LLM calls. Using free-tier edge services and client-side PDF generation, the prototype ran for under $5/month (LLM API costs plus domain) in early production. The post details trade-offs (limitations of Workers and D1), operational lessons (remote debugging, secrets, migrations), and observed benefits like lower latency across Brazil and ~40% reduction in LLM calls due to caching.
