Show HN: Costile – open-source proxy, blocks AI API requests when budget is hit

I got a surprise bill. Nothing catastrophic, but enough to make me dig into why — an agent had hit a retry loop and kept calling the API for hours. There's no way to set a hard cap on the Anthropic or OpenAI APIs. You can get an email after the fact, but nothing that actually stops requests mid-flight.So I built a proxy. You swap one environment variable, it routes through Costile instead of calling Anthropic directly, and when you hit your daily or monthly limit it blocks further requests

Show HN: I built a contextual explainer to replace my dictionary extensions

A brief generational overview of the tech industry

Modern consumer-focused technology, the finished products that we use in our day-to-day lives, is defined by the tech industry(AKA Big Tech, tech companies, the Internet, whatever you want to call it). Broadly speaking, this is the industry that has been the main driver of innovation in the past 50 years: producing wealth, increasing the standard of living, and improving human productivity. As of 2026, I can see this industry as having 2 clear generations of societal impact. I will list various

Show HN: Mimikos – Zero-config mock server that infers API behavior from OpenAPI

I built a mock server that reads an OpenAPI spec and serves realistic, deterministic responses — no mock definitions, no config files.``` mimikos start petstore.yaml ```That's the entire setup. Mimikos parses your spec, classifies each endpoint (create, fetch, list, update, delete), and generates schema-valid responses with realistic data. Same request always returns the same response, so it's safe for snapshot tests and CI.What's different from Prism, WireMock, etc.:Most mock ser
