Fact0

What it does

Log every autonomous action, tool call, and human approval in a tamper-evident cryptographic chain. Pass enterprise security reviews in days, not months.

Unblock enterprise deals by proving tool boundaries, data exfiltration protections, and unsupervised loop constraints. Pass security reviews in days, not months.

The audit layer built for AI agents, not generic SaaS. Prove your agent's tool permissions, data exfiltration guards, and human-in-the-loop validation to enterprise CISOs. Track every tool execution, input parameters, and output results with origin attributes. Mathematical proof that logs haven't been altered, verified by third-party auditors. Evidence packs stamped with an Ed25519 digital wax seal. Auditors mathematically verify reports. Async batching - your app keeps running and agent loops never slow down. Add our SDK to your agent or backend. Important actions are recorded with actor, resource, and outcome. Each event links to the one before it. Change any record and the chain shows…from fact0.io

  FactIQ – a realtime econ+finance database for AI agentsJul 2026 · github.com · ▲7

  Hey HN, we built an Econ+Finance database to let AI agents do investment research. We spend a lot of tokens to organize macro releases and SEC filings into a clean format, so that your agents have more context to do actual analysis. The problem AI agents are great at data analysis. But they become ineffective if most of their context window is spent on gathering and cleaning data, instead of validating hypotheses. Data in the wild is messy and rarely standardized. Definitions and measurements change over time. This problem is compounded by a fragmented data universe. Point solutions exist…

  Talanoa▲341

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
