Articles on the tools and platforms that change the economics of building software: AI tooling and its real costs, infrastructure choices for small teams, and what new technology actually means for a builder's bottom line.
A new benchmark pushed Postgres LISTEN/NOTIFY to 60,000 writes per second. The documented limits, the doorbell pattern, and the four conditions that actually justify a second system.
Open-weight models served over API now cost 10-50x less than frontier flagships. The price map from providers' own pages, a worked monthly bill with a 100x spread, and a three-tier routing rule.
A researcher found a GitHub admin token, access to hundreds of repos, inside a camera's login page, put there by the build tool. The same failure mode lives in ordinary web builds; the fix takes an hour.
A shared card number is an open-ended permission slip. Virtual cards - one per vendor, capped at the plan price - turn every subscription into a budget that enforces itself.
New image models like this week's Flux 3 make generation nearly free. The constraint is no longer cost - it's accuracy: a listing image that oversells the product converts into returns and disputes.
Apple and Google both halve their commission for developers under $1M - but neither discount is automatic. The programs, the cliff-versus-marginal difference between them, and the enrollment checklists.
Stack paralysis is procrastination wearing a research costume. The 2025 Stack Overflow data says the answer is boring on purpose: the most-used tools are the most-answered, most-hireable, most-survivable ones.
Solo builders quietly accumulate overlapping AI subscriptions until the stack costs more than hosting. A four-step audit, inventory, overlap, per-use cost, subscribe-vs-API, for cutting spend without cutting capability.
For decades, 'solo founder' meant choosing which half of the company to neglect. The economics quietly changed. Here's what one person can realistically run in 2026, and where the ceiling still is.
