Solo founder builds $5/month server monitoring SaaS for Latin American SMBs on Cloudflare

·2 views

A solo developer built Pulse, a server monitoring SaaS targeting small and medium businesses in Latin America that lack affordable, easy-to-use infrastructure monitoring tools. The platform runs entirely on Cloudflare Workers, Turso (libsql), and R2 storage, with a Go agent deployable on Linux, macOS, Windows, or Docker via a single command. Operating costs stay around $5 per month for the first hundred customers, with alert latency under one second from threshold breach to notification. The architecture consolidates compute, database, storage, AI-powered alert interpretation, and billing into a single Cloudflare Worker with one scheduled cron job. The project was designed around fixed-tier pricing, minimal setup, and native LATAM channels like Telegram, addressing a gap left by enterprise-grade observability tools with unpredictable per-metric billing.

VisualRefiner converts HEIC, images, and video entirely inside the browser

A developer has built VisualRefiner, a file conversion tool that processes images and video entirely within the user's browser, requiring no server uploads or account creation. The tool handles HEIC-to-JPEG conversion, image compression, and format transcoding using the Canvas API, WebCodecs, and WebAssembly. Because the site is a fully static export with no backend, files never leave the user's device by design rather than by policy. HEIC files, which most browsers cannot natively decode, are handled via libheif compiled to WebAssembly and loaded only when needed to keep initial page load sizes small. Heavy dependencies like the 2 MB HEIC decoder are fetched on demand through dynamic imports, ensuring the homepage remains lightweight for users who may never use those features.

Former Waitress Pivots to Cybersecurity in Her 50s After Identity Theft

A woman in her 50s made a mid-life career change into cybersecurity, driven by an identity theft incident that occurred roughly 20 years ago and stayed with her ever since. Having no prior technical background, she enrolled with TripleTen to gain hands-on skills in security operations. As part of her training, she completed a SIEM project integrating Windows Defender logs into the Wazuh platform to detect malware events. The project required configuring the Wazuh agent on a Windows system and correctly restarting the service to ingest the new log source — a step she initially missed. She describes the experience as personally transformative, saying it gave her the ability to read security signals that once felt invisible to her.

Developer shares six critical WordPress checks to run before any site goes live

A developer writing for DEV Community has outlined six WordPress-specific pre-launch checks that are commonly overlooked in AI-assisted builds. The checks cover search engine visibility settings, default admin usernames, debug mode configuration, leftover debug log files, the file editor in wp-admin, and XML-RPC exposure. These issues rarely cause visible errors during testing, making them easy to miss even when a site appears fully functional. The author notes that maintaining a dated record of completed checks is more reliable than relying on memory, especially for client handovers. To streamline the process, they built a free WordPress plugin called Noshi-Kanamer that audits all six items automatically and generates a plain-text launch report.
