Extractor uses LLMs to reliably extract structured data from any webpage. Unlike traditional scrapers that break when HTML changes, Extractor understands the content semantically.

jcode is an open-source, Rust-built terminal application that acts as a harness for AI coding agents. Unlike Electron-based competitors, it achieves roughly 14ms time-to-first-frame and uses approximately 6× less RAM for a single session — scaling even better with concurrent agents (about 2.2× extra RAM per session vs 15–32× for most alternatives). The tool features a custom semantic memory system that automatically recalls relevant context from previous sessions without requiring explicit tool calls. Agents can form "swarms" — collaborative groups that share messaging channels, auto-resolve conflicts, and even self-modify their own source code, rebuild, and reload. It also ships a Rust-based Mermaid renderer claimed to be 1800× faster than JavaScript alternatives. jcode supports 20+ LLM providers including Claude, OpenAI, Gemini, and local Ollama models. For developers frustrated with heavy, slow agent tooling, this is a genuinely different approach that treats performance as a first-class feature rather than an afterthought.
Reviewer scorecard
“Traditional web scraping is brittle. LLM-powered extraction that understands content structure is the right approach. Works on messy pages where CSS selectors fail.”
“14ms startup and 6× lower RAM than competitors? This is the kind of engineering that makes you rethink your whole toolchain. The multi-agent swarm coordination is genuinely novel — not just 'run two Claude windows.'”
“The LLM cost per extraction makes it expensive at scale. But for high-value data extraction where accuracy matters more than cost, it is worth it.”
“The benchmarks feel cherry-picked, and 'agents editing their own source code' is a footgun in disguise. Until there's a production track record and documented guardrails, I'd keep this in the experimental bucket.”
“Web scraping becomes web understanding. As more AI agents need to read the web, tools like Extractor become essential infrastructure.”
“Rust-native agent infrastructure with semantic memory and self-modifying swarms is a preview of what professional AI development environments look like. The performance ceiling matters enormously as agent workloads scale.”
“The TUI design is surprisingly polished for a Rust CLI project. Fast, responsive agent loops mean less 'waiting for the spinner' and more actual creative flow when building with AI.”
