Writing on AI crawlers, infrastructure, webhooks, APIs, and developer tools.
GPTBot, ClaudeBot, and meta-externalagent crawl far more aggressively than Googlebot. Here's what that does to your Vercel/AWS bill — and how to find out which bot is responsible.
We fetched robots.txt from 20 developer platforms on September 22, 2026. Only 1 of 140 platform-and-bot combinations results in a full block. The Vercel irony, GitHub's careful curation, and why meta-externalagent is blocked by nobody.
Copy-paste configs for every major platform. Covers GPTBot, ClaudeBot, meta-externalagent, Bytespider, PerplexityBot, and 12 more.
Complete reference. Every major AI crawler, the exact User-Agent string, compliance notes, and a copy-paste block-all snippet for robots.txt.
Stripe retries failed webhooks for 72 hours, but your app never gets notified when they all fail. Here's how to detect it before it costs you orders.
Webhooks fail silently after retry exhaustion. Stripe retries for 72h then gives up with no alert. Here's the retry mechanics, real failure scenarios, and minimum viable webhook monitoring.
Stripe retries for 72 hours then gives up without telling you. Here's the retry schedule, why failures are invisible, and a Node.js handler that actually alerts you.
Honest comparison: Hookdeck, webhook.site, RequestCatcher, DIY logging, and WebhookPulse early access. Which to use when you just need to know when it fails.
Stripe, Twilio, SendGrid, GitHub all send deprecation notices to billing emails nobody reads. Production breaks on a Tuesday. Here's how to catch it in advance.
The 90-day notice was in the changelog. Nobody subscribed. Here's how to monitor Sunset headers, parse changelogs, and write synthetic tests before the Thursday outage.
Honest comparison: manual changelogs, Optic, Bump.sh, DIY Sunset header parsing, and APIWatch early access. What each covers and when to use it.
Real cloud pricing data: most staging environments sit idle 86% of the time. A typical 3-service team wastes $60–150/month on unused compute.
A $100/mo staging env at 5% utilization wastes $95/mo. How idle cloud instances inflate your bill invisibly — and what to do about it.
Honest comparison: Kubernetes hibernation operators, Render suspend, Railway sleep, manual scripts, and IdleDown. Feature table and when to use each.
The nightly sync stopped Thursday. You found out Monday — from a user. Here's why cron fails invisibly and how to add a dead man's switch in one line.
Honest comparison of healthchecks.io, UptimeRobot, Dead Man's Snitch, Cronitor, and DIY approaches. What to use and when.
LLM API costs spike without warning because billing is opaque by default. Here's how to add real-time cost monitoring and per-feature attribution to your app.
Practical techniques to cut OpenAI and Anthropic API bills: model selection, token optimization, caching, and per-feature cost attribution. Real numbers included.
47 commits: "fix typo", "WIP", "more fixes". Here's how to pipe git log into an LLM and generate a real changelog automatically, with a GitHub Actions workflow included.
Manual changelogs are always out of date. Your git history already has the data — it just needs to be turned into human-readable notes. Here's how AI-assisted commit parsing works and a ready-made solution.
Honest comparison of Keep a Changelog, conventional-changelog CLI, Release Drafter, Changesets, and PushLog. Features, pricing, and what to use when.
