Confidence is a product intelligence platform built by Spotify. Spotify's approach to building products has always combined data with judgment and taste, and that scientific rigor is what Confidence brings to customers. Confidence is born from experimentation, but that’s now part of a wider story. Confidence analyzes your user signals, surfaces what's working, suggests the next move, and validates the hypothesis before it ships. You stay in the loop and approve the moves that matter.

This tool is ideal for system administrators, power users, and developers who need to deploy clean, efficient, and purpose-built Windows 11 environments.

Rust is a systems programming language designed for performance, safety, and productivity. It solves the common problems of memory errors and data races by enforcing strict compile-time checks, eliminating entire classes of bugs. It's for developers building everything from high-performance web services and command-line tools to embedded systems and WebAssembly modules, who need both low-level control and modern developer ergonomics.

iFixAi is an independent auditing platform for AI agents. It solves the critical trust gap where agents can pass performance evaluations while secretly hiding information, overriding decisions, or acting without authorisation.

You’ve spent years meeting people. A lot of those relationships are now buried in your inbox. Blade helps you find them again.

Whether you’re launching something, asking for feedback, or inviting people to an event, you’re starting with people who already know you.

Compared with Dependabot and Renovate, LegacyFixer focuses on security-first scanning of Python dependencies. It reports vulnerability findings even when an automated fix is not appropriate, and creates a fix pull request only when its policy and validation checks allow it. Each scan produces an explicit outcome, including detect-only (NO_ACTION) when no fix PR is created. LegacyFixer runs as a GitHub App on Google Cloud Run.

Make0 Brain is a personal memory store that works across ChatGPT, Claude, Cursor, and other MCP-compatible AI tools.

Explaining to cursor/claude code/codex UI changes: spacing is off, this card is too tall, that CTA is too loud, mobile looks weird.....is annoying. With EditUI you open your actual app/website in Chrome, click anything, leave a quick instruction, keep reviewing, then send the whole batch to Claude Code at once. No repo setup. Just a Chrome extension. Free and open source. No signup, no backend.

AI assistants are islands. Yours knows the plumber's coming Tuesday; your wife's knows nothing, and you're back to being the messenger. It's a neutral relay layer between AI assistants. Tell your assistant to share specific facts with specific people — "let Sam know the plumber's coming 8 to 10" — and their assistant picks it up. Nothing moves until you approve what's sent. It also works solo: add the connector to two or more assistants you own — Claude at work, ChatGPT at home — and relay facts

Dashrendr is a visual dashboard builder made for embedding in your SaaS. Drag charts onto a grid and have a dashboard ready in minutes, then get data in two ways: connect a data source, or POST JSON from your backend. Your app already knows who's logged in, so each customer only sees their own data, with no row-level security to set up. And when someone wants a chart changed, anyone on the team can do it in the builder, no code or new deployment needed.

The inspiration for Etchv came directly from friends who raised concerns about the growing ease of unauthorized media copying without attribution. To address this, Etchv embeds an invisible watermark inside images, PDFs, or short videos that survives modifications like screenshots, format changes, and file compression. There's a live demo where a watermarked PDF page gets screenshotted and the watermark ID is still successfully recovered: https://etchv.com/demo/trace
