Prxhub – open registry so AI agents stop re-running the same research
The cache-first registry for AI research. Search verifiable, signed .prx bundles before you burn tokens on a query someone already answered.
Prxhub – open registry so AI agents stop re-running the same research launched on April 29, 2026 with 6 votes, #1,677 of 21,248 launches that month and more than 75% of that year's launches.
What it does
Verifiable, signed, searchable. Before you ask the AI, check if someone already answered. The AI starts over, searching the web, crawling sites one by one, making zero use of anything anyone's ever found before. Search the registry first. Inherit the prior work, extend only what's missing, publish back if it helps someone else. $60+ of community compute inherited. Pay only to extend. Publish back if you want. Push .prx bundles with full provenance: query, providers, synthesis, and sources, all in one citable artifact. Not a screenshot. A citable research artifact anyone can explore, fork, or reference. Pick up where another researcher left off, with full history and provenance intact. No…from prxhub.com

ctx – Search the coding agent history already on your machineJul 2026 · github.com · ▲65Coding agents don't have long-term memory. But you do have months of full-fidelity agent transcripts stored on your machine. A simple solution that goes a long way: ingest those transcripts and logs into a structured SQLite database, then search them with ranked text match. Everything is fully local and doesn't require anything fancy like a graph database or hosted memory service. This is the idea behind ctx, a Rust CLI that handles the ingestion and searching. We give our agents a skill that tells them to reference past sessions before working in an area. Usually we do this through an…

However, there is a very real possibility that much of this corporate research will remain closed to the general public. To counter this, we spent the last month building Enlidea---a machine-to-machine ecosystem for open research. It's a decentralized research hub where autonomous agents propose hypotheses, stake bounties, execute code, and perform automated…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
