Urlx – an agent-made Rust replacement for curl/libcurl
Recently several AI labs have published experiments where they tried to get AI coding agents to complete large software projects. - Cursor attempted to make a browser from scratch: https://cursor.com/blog/scaling-agents - Anthropic attempted to make a C Compiler: https://www.anthropic.com/engineering/building-c-compiler A few weeks ago I posted xmloxide, an agent-made Rust replacement for libxml2 made by pointing Claude code at the libxml2 test suite: https://news.ycombinator.com/item?id=47201816 curl is arguably the most widely deployed…

What it does
A memory-safe Rust reimplementation of curl and libcurl. - jonwiggins/urlx
urlx is a memory-safe, from-scratch reimplementation of curl and libcurl. No OpenSSL. No unsafe outside the FFI boundary. 1,300 of curl's own tests pass against urlx. # It's curl. Just in Rust. urlx https://example.com urlx -d ' {"key":"val"} ' -H ' Content-Type: application/json ' https://api.example.com urlx -Lo file.tar.gz https://example.com/file.tar.gz urlx -u user:pass --digest https://api.example.com/admin urlx -Z https://a.com https://b.com https://c.com # parallel transfers Why? curl is one of the most important pieces of software ever written. It's also 180,000 lines of C with a long history of memory safety CVEs. urlx asks: what if we just rewrote it? cargo install urlx-cli #…from github.com

Xmloxide – an agent-made Rust replacement for libxml2Feb 2026 · github.com · ▲64Recently several AI labs have published experiments where they tried to get AI coding agents to complete large software projects. - Cursor attempted to make a browser from scratch: https://cursor.com/blog/scaling-agents - Anthropic attempted to make a C Compiler: https://www.anthropic.com/engineering/building-c-compiler I have been wondering if there are software packages that can be easily reproduced by taking the available test suites and tasking agents to work on projects until the existing test suites pass. After playing with this concept by having…
Notte Browser Agents2025 · notte.cc · ▲275Hey HN, We’ve been building browser agents for a while. In production, we kept converging on the same pattern: deterministic scripts for the happy path, agents only for edge cases. So we built Demonstrate Mode. The idea is simple: You perform your workflow once in a remote browser. Notte records the interactions and generates deterministic automation code. How it works: - Record clicks, inputs, navigations in a cloud browser - Compile them into deterministic code (no LLM at runtime) - Run and deploy on managed browser infrastructure Closest analog is Playwright codegen but: - Infrastructure…
display.devMay 2026 · display.dev · ▲183Last week's post from Thariq "The Unreasonable Effectiveness of HTML" went viral in X. He made a good point about HTML being the more expressive and human friendly alternative to markdown files. I completely buy in where he's coming from, I've been asking Claude Code to create me HTML files to better understand what we're planning and building together. What Thariq didn't address was the part of sharing and collaborating on these HTML artifacts (he proposed uploading to S3). While I've been heavy user of HTML artifacts to share quarterly plans, implementation specs, technical guides and…
