developer tools

A command guard for AI coding agents that blocks destructive git and shell commands before they run, with support for multiple agent and CLI tools.

A Mac-native menu bar app that tracks AI token usage, shows spend by model, and pops up break reminders when usage crosses configurable thresholds.

Blocks.ai is an infrastructure and network layer for AI agents, offering outbound-only connectivity, routing, auth, billing, streaming, and a marketplace/network for builders and callers.

Nicasa is a native macOS image viewer and Chrome extension for fast image browsing, with AI image enhancement, smart image extraction, screenshot capture, and local-only processing.

Abralo is a native desktop app for running multiple Claude Code agents at once in one window. It focuses on keeping several agents visible, showing token usage, and surfacing when an agent needs attention.

Bootable Rust no_std kernel built as an inference substrate for LLMs, with tensor-native memory allocation, layer-boundary scheduling, and streaming-focused runtime primitives.

A web utility for creating end-to-end encrypted share links for single-file HTML generated by agents. It stores ciphertext for seven days and lets browsers decrypt and render the page from the URL fragment in a sandbox.

AutomatiQ is a Python CLI that records a browsing session and uses vision and LLM steps to generate a standalone HTTP-based automation script.

A CLI for running long-lived autonomous coding agents in isolated Docker containers, with detach/reattach, review, commit, push, and optional browser preview workflows.

Local software-factory CLI that coordinates coding agents like Claude Code and Aider into parallel, gated worktree-based development runs.

A TypeScript SDK for browser-native AI APIs and WebMCP, with composable wrappers, streaming, AbortSignal handling, and optional React hooks.

An AI-powered product discovery platform with a developer-facing MCP server and API for live catalog search, product details, pricing, and merchant links.

An open agent-identity protocol with a shipped reference implementation, TypeScript SDK, conformance test vectors, and protocol docs for identity, discovery, payments, and audit flows.

A native macOS app that uses Claude to act as an autonomous coding agent for Apple platform development. It can inspect an Xcode project, make edits, build, launch, and validate changes with xcodebuildmcp and UI automation.

A local tool that estimates GitHub Copilot AI-credit costs from usage data and generates an HTML report. It pulls from VS Code, OpenCode, Pi, Copilot CLI, and Copilot for Xcode, with CLI options for date ranges, model mapping, and JSON output.

Open-source harness for executable security regression testing of agentic applications and MCP-integrated systems, with scenario files, policy assertions, trace-based evaluation, and JSON output for CI or local use.

A detailed post from pact0 about testing whether blank AI agents could complete a real product workflow, what failed, and the fixes they shipped after the audit.

ObserverBench is an interactive benchmark and guided demo for testing whether internal AI monitoring methods help make safer decisions, not just better predictions. It includes real-model results, benchmark tasks, and a no-login walkthrough showing how warning scores affect review and harm that slips through.

OpenAI’s documentation for its Agents API, covering how to build and run cloud agents with the OpenAI platform. The page surfaces core concepts, quickstart material, SDKs, webhooks, tracing, tools, and related agent-building resources.

Open-source text-to-SQL engine tuned to your own database, with configurable pipeline stages, policy checks, and an evaluation harness for measuring performance on real schemas.

brw is a semantic browser control tool for agents. It runs a real visible Chrome/Chromium browser and exposes control through MCP and HTTP, with stable refs, semantic page snapshots, and post-action observations.

An open-source Stripe-like payment layer for AI agents and paid MCP tools, with spend authorization, per-call charging, and settlement flows for test credits in beta.

A self-hostable MCP endpoint that centralizes accounts, memory, skills, secrets, and access controls for AI agents. It supports multiple providers, profile-based permissions, audit logs, and deployment on your own machine or cloud.

Hedgemony is a Python tool that checks AI-written code for fabricated packages, invented APIs, impossible calls, and contradictions between code and stated examples, using interpreter and registry checks rather than another model.
