developer tools

Open-source checker that opens a generated web page in a real browser, inspects rendered controls, and runs mechanical checks without tests or an LLM.

Vigilator is a human-in-the-loop layer for AI agents, offering approvals, live agent monitoring, escalation routing, analytics, audit logs, notifications, and webhooks.

TokenDelivery.ai is an OpenAI-compatible API for open-weight LLMs with deterministic outputs, prepaid per-token billing, and a playground for testing prompts, images, video, and sampling settings.

A public leaderboard comparing how different language models solve Redactle under several evaluation setups, with cost, speed, and solve-rate data.

HEIDES is a deterministic local harness for AI coding agents that maps a codebase, grounds plans against the current graph, and checks proposed patches for conflicts, edge cases, and security issues before changes land.

A local zero-dependency sandbox for agents that records files, commands, database activity, network access, and screenshots for review before approving changes.

Sloppie is a Linux development environment for coordinating multiple coding-agent tasks with a dashboard, diff review, async comments, and real terminals per task.

Local privacy gateway that redacts sensitive text before sending prompts to external LLMs, then reconstructs the final answer locally.

Self-hosted multi-agent federation for running Hermes agents and OpenClaw minions with a board, tender market, memory layers, and decision provenance.

A repo-improving agent harness that researches a codebase, proposes ideas, waits for human approval, and then drives execution with SHA-bound merge gating.

A CLI bridge that wraps legacy MCP stdio servers so they can run behind the newer stateless 2026-07-28 protocol. The page includes a concrete usage example, client configuration snippets, compatibility behavior, and known limitations.

A Git-backed CLI for sharing agent skills, settings, and MCP fragments across repositories with per-project lockfiles and update workflows.

A Claude Code plugin that turns waiting time into a terminal Pokémon mini-game. It shows wild Pokémon while Claude works, runs locally, and includes install steps plus update behavior.

Live pricing and cost calculators for 232+ AI models, with monthly bill estimates, token math, and vendor-by-vendor price tables.

A Lean 4 relational knowledge language for project relationships, rules, and queries, with a Clojure runtime/toolchain and examples inspired by Zanzibar.

A language server for agent skills that turns /skill-name and $skill-name into navigable symbols with completion, rename, go-to-definition, and reference tracking across editors like VS Code, Zed, Neovim, and Helix.

Dependency-free Python library that compiles a declarative JSON query format into safe, parameterized SQL for LLM workflows, REST APIs, and frontend-backed data tables.

Local open-source coding agent for developers, with a macro-style command workflow and benchmark results showing fewer turns and better pass rates than Codex CLI in the published comparison.

Persistent memory for coding agents that stores hard-won codebase discoveries and revalidates them when files change. The repo describes a CLI hook flow for Claude Code and Codex, with install steps, command examples, and an evaluation claim showing fewer tokens on repeat questions.

A harness that runs MCP servers in a disposable Linux sandbox and logs their real startup behavior, including file access and outbound network connections.

A Claude Code plugin and MCP server that keeps a persistent, read-only memory of a repo so agents can ask broad codebase questions without re-reading files every session.

GetSuperpower is a CLI and workflow bundle for coding agents that packages multi-step agent workflows into one installable skill tree.

Local-first code intelligence MCP for AI coding agents. It gives tools like Claude, Cursor, Codex, and other MCP-compatible agents an indexed evidence layer for repo search, symbol lookup, impact analysis, and test selection before editing code.

A local MCP server that builds a deterministic architecture graph of a codebase so AI coding agents can inspect modules, symbols, routes, dependencies, and cross-repo relationships from source-backed facts.
