A self-hosted, open-source shipping platform that gives a single API and dashboard for rating, purchasing labels from, and tracking packages across many carriers, such as UPS, FedEx, DHL, and USPS.

• APIs
• Backend

A human-verified evaluation harness for scoring large language models as autonomous agents, requiring a model to pass the same task in three independent trials before it counts as a success.

• AI evals

An open-source Python platform that uses large language models to automatically design and optimize algorithms, with unified interfaces across methods, tasks and models plus a graphical interface for running experiments.

• Libraries

A set of Swift macros that generates a type's Codable implementation, covering flattened nested keys, fallback keys, default values, custom coding strategies, and untagged enums, without hand-written boilerplate.

• Libraries

A fast agent harness for long-running, multi-model, tool-using AI systems, installed as a Python package that starts a chat-style terminal session and can also run inside a bundled desktop app.

• Agent frameworks

An MCP server that checks whether a proposed app idea already exists by scanning GitHub, npm, PyPI, Hacker News and Stack Overflow, returning a 0-100 score and competitor evidence before any code is written.

• MCP servers

A tool that converts an existing open large language model into a calibrated decision model, returning a typed answer and a real probability for a choice, a yes/no or a score, without any additional training.

• Models
• Inference

A voice assistant that talks through a project idea with the user, writes the resulting design to a file, then starts and supervises a real Claude Code session on it, announcing out loud when the agent needs input.

• Coding agents
• Speech

A modular Swift SDK for running text-to-speech, speech-to-text, voice activity detection, and speech-to-speech models on Apple Silicon through MLX, with importable modules for just the models an app needs.

• Speech
• Libraries

A command-line tool that automatically records every action a coding agent takes inside a project, so a change can be traced to the exact prompt that produced it and any step can be inspected afterward.

• AI evals

An open-source agent engineering platform that traces, evaluates and monitors AI agents so a team can debug them together, available as a managed cloud service or self-hosted with Docker.

• AI evals

An implementation of DFlash block-diffusion speculative decoding for the MLX framework on Apple Silicon, generating multiple tokens per pass while guaranteeing output identical to standard autoregressive decoding.

• Inference

An Unreal Engine 5 simulation platform for developing and evaluating LLM and vision-language model agents in realistic physical and social city environments, from a lightweight starter map to fully custom worlds.

• AI evals

A local-first visual generation studio that runs image and video jobs from several providers on a user's own machine, keeping every generation's prompt, timing and settings so results can be branched and reproduced.

• Generative media

A self-hosted memory layer, deployed on a personal Cloudflare account, that stores notes once and makes them retrievable by meaning from Claude, ChatGPT, Cursor or any other MCP-compatible AI tool.

• Agent memory

An LLM-driven data analyst that runs in a persistent Python kernel, writing and executing its own code one cell at a time and re-running its cited results in a fresh kernel before presenting a report.

• Data engineering

A community-maintained collection of more than three hundred goal-oriented code patterns for the Effect-TS library, spanning error handling, concurrency, streams, schema, and testing, with a searchable command-line tool.

• Tutorials

A free, open-source archive manager for macOS that opens more than forty archive, disk-image, and compression formats, letting you browse and preview contents, including nested archives, without extracting them.

• Desktop utilities

An open-source AI security agent that runs in a terminal, following runbooks and switching between specialized agents while tracking findings, evidence and reports for authorized application-security and penetration-testing work.

• Security

A command-line tool that estimates whether a Hugging Face model will fit and fine-tune on a given consumer GPU, and recommends batch size, sequence length, LoRA rank and quantization before any weights are downloaded.

• Models
• CLI tools

An MCP server that lets an AI assistant run SSH commands and transfer files on remote servers through a standardized interface, without exposing SSH credentials to the model.

• MCP servers
• Hosting

An open-source, AI-powered harness for data engineering that gives a coding agent more than 100 deterministic tools for SQL analysis, column-level lineage, dbt and warehouse connectivity across ten cloud warehouses.

• Databases
• Data engineering

A standalone server that connects a modified JADX Android decompiler to large language models over MCP, so an assistant can read decompiled app code and follow along during reverse engineering.

• MCP servers
• Security

A ranked, weekly-updated catalog of AI agent harnesses and orchestration frameworks, with copy-paste templates and playbooks, and an MCP server and dataset an agent can query to pick one.
