AI tool

An interactive browser city that visualizes how an LLM works, with live transformer mechanics such as tokenization, attention, KV cache, residual stream, and sampling.

Free hands-on labs for prompt injection and LLM security training, with real models, a context trace view of assembled prompts, and a multi-level Gauntlet challenge.

A curated-taste API for architecture, art, design, and photography, with both REST endpoints and a native MCP server for AI agents. It offers search, similarity, provenance, and taste metadata across 2,500+ hand-selected projects, plus free keys and documented pricing.

A fast, private, self-hostable AI chat app for OpenRouter. It supports bring-your-own-key usage, model selection across many providers, attachments, web search, portable history, and both hosted and self-hosted deployment.

LLMIntel is a runtime telemetry and cost dashboard for LLM apps. The live demo shows spend by model, API key, environment, and tag, plus at-risk spend for retiring models and optimization suggestions.

A free public API for LLM pricing, specs, benchmarks, and cost calculations across 1,000+ models. It offers no-auth endpoints, CORS support, an OpenAPI spec, and a LiteLLM-compatible cost map that refreshes daily.

Open-source Chromium fork that aims to keep browser automation and scrapers from being blocked by patching fingerprint surfaces inside the engine. It connects over CDP and is positioned as a drop-in replacement for Playwright, Puppeteer, and other CDP clients.

An MCP server that gives AI agents access to 8,500+ curated awesome lists and 1.3M+ resources, with hosted and local setup options plus tool docs and example queries.

Local-first document AI that extracts structured JSON from PDFs, scans, images, text, and Markdown without sending data to a third-party API. It includes a REST API, CLI, and Web UI, and supports local execution on macOS Apple Silicon and Linux NVIDIA systems.

A Model Context Protocol server for Uptime.com that lets AI assistants manage monitoring checks, alerts, outages, status pages, and account usage through tools and hosted or self-hosted deployment options.

Local-first observability and evaluation layer for production forecasts. Captures forecasts, validates them, computes horizon-aware metrics, and serves a read-only local UI for comparing runs.

Local dashboard for Claude Code sessions with live monitoring, session history, usage charts, resume commands, and LLM usage analysis.

Self-hosted observability and control plane for production and coding AI agents, with live timelines, fleet-wide feeds, token budgets, MCP allow/block rules, and support for Claude Code plus a Python sensor.

AI code review tool that scores code against six decay-risk dimensions inspired by twelve classic engineering books, with book citations, severity labels, and remediation guidance.

Crit is a local-first review tool for AI coding agents, letting users comment on plans and code diffs, iterate through multiple review rounds, and share reviews when needed. It supports several agent ecosystems and can be installed as a single binary.

Tilde is an agent sandbox platform for running AI agents and pipelines on real data with transactional commits, rollback, audit logs, and a versioned filesystem that can compose GitHub, S3, and Google Drive.

Open-source AI sandbox infrastructure for running code, browsing the web, and isolating agent workflows inside disposable microVMs.

Aurra is memory infrastructure for AI agents, with bi-temporal versioning, source-cited memory history, and an automatic supersession feature that uses an LLM classifier to decide when new facts replace old ones.

Open Bias is an open-source reliability harness for LLM apps and agents that enforces rules at runtime. It sits between your app and an LLM provider, using RULES.md policies to trace, block, or fix off-policy behavior.

A React mini-arcade component for turning loading screens into playable one-button games while long tasks run. It includes multiple game modes, skins, score tracking, achievements, and simple props for embedding in apps.

prxhub is an open registry for AI research bundles, built around verifiable .prx artifacts, search, provenance, and agent-friendly publishing via MCP and CLI.

KinoPipe is an FFmpeg-as-a-service platform for AI agents and developers, offering typed video-editing tools over MCP and REST. The page shows supported actions like trim, resize, compress, subtitles, and scene splitting, plus playground access, pricing, and deployment details.

A hosted relay that lets Claude, ChatGPT, or any MCP client securely access local, NAT'd, or firewalled MCP servers through one connector and a single URL.

grith is a Linux security proxy for AI coding agents that supervises file, process, and network actions at the OS level before they execute. It supports tools like Claude Code, Codex, Aider, Cline, and Goose, with local audit logging and profiles for common agent workflows.
