Free Developer Tools

Docs.dev is a deployable documentation template that runs as a Cloudflare Worker in your account, using your GitHub repo as the source of truth and agent-powered drafting (e.g., Claude Code or Codex) to generate reviewable docs branches that your team publishes via commit.

Bullet is a fast coding agent and developer tool that routes, searches, and executes code-focused tasks with a tight loop to minimize latency — offered as a macOS download and currently available in private beta.

Codify is a cross-platform tool that declares and automates developer environments as code—via a CLI and dashboard—so teams and individuals can standardize, reproduce, and apply development setups on macOS, Linux, and WSL.

Sign in with ChatGPT lets developers add ChatGPT account authentication to web apps so users can access OpenAI AI capabilities (works across free and paid ChatGPT accounts). It provides React components and helper methods to obtain encrypted, locally stored credentials and call the AI SDK from the signed-in account.

LLM Status is a model-lifecycle tracker and CLI that scans code repositories for AI model IDs, flags models that are deprecated or retiring, and offers automated fixes, CI checks, and cloud alerts to keep projects off retirement schedules.

SightDiff is a local visual regression tool that captures pixel-perfect screenshots of configured pages and states before and after an AI agent (or a human) makes changes, producing a proof sheet that highlights changed surfaces and verifies unchanged pages as a pre-commit gate.

Zlvox is a privacy-first collection of 30+ fast, browser-based developer utilities — AI tools, PDF and image processors, JSON/data utilities, QR and security tools — designed to run client-side with no sign-up or server-side data retention.

TokenMaxxer is an AI usage intelligence platform for developers that tracks every AI token burned across coding tools and models, showing counts, estimated cost, and a global leaderboard so developers can monitor and compare usage.

Vestige is a Visual Studio Code extension that makes large, LLM-generated code changes reviewable by building local call-graphs and file-dependency graphs, surfacing blast-radius analysis, guided review cards, and LLM-generated summaries/explanations.

Scribe is a local-first CLI knowledge-base generator that automatically mines developer artifacts (git history, Claude Code & Codex sessions, self-sent URLs, and drop files), triages them with FTS5, and writes a cross-project, typed-graph markdown wiki in git for agents to read before they act.

AI Meter is a macOS application that measures token usage from local coding agents and estimates associated electricity and direct cooling-water use, running fully on the user's machine with no accounts and no usage data leaving the device.

Termic is a free, open-source (AGPL-3.0) desktop app that runs vendor AI CLIs (claude, codex, gemini, grok, antigravity, etc.) in real PTYs, organized into tasks and git worktrees for developer workflows, with sandboxing, project-aware tools, and built-in editor/diff views.

Lific is a self-hosted, single-binary issue tracker and planning tool designed for coding agents and human teams — it exposes a web UI, CLI, REST API and MCP tool surface so agents and developers can track plans, issues, comments, and audits on your own server.

Darby is a minimal, fast, and themeable Hugo documentation theme that provides dark mode, client-side search, polished code blocks, callouts, and navigation components out of the box for technical docs sites.

DDS Hub is a developer-first API relay that provides low-latency, privacy-focused access to Anthropic Claude models and Codex GPT series, offering enterprise static IPs, streaming support, and local payment methods (Alipay/WeChat Pay).

Denvr AI Cloud is a Canadian-founded private AI platform offering sovereign cloud and on-prem AI infrastructure: GPU compute, managed inference, and NVMe data systems with developer tooling and APIs for teams requiring data residency and production-grade AI operations.

local.ai is a free, open-source native app for managing, verifying, and running AI models locally (offline) with CPU inferencing; it emphasizes privacy, low memory footprint (Rust backend), and simple model/server workflows.

SQLAI.ai is an AI-powered SQL tool that generates, optimizes, validates, formats, explains, and converts SQL (and some NoSQL) queries to help analysts, engineers, and data teams ship production-ready queries faster. It supports dozens of database engines and offers schema-aware generation, live connections, and a VS Code‑style query editor.

Theneo is an all-in-one developer portal for API references, guides, changelogs, and private customer portals that combines real-time collaboration and integrated AI features (Ask AI, MCP, llms.txt) to keep docs synchronized between engineers, writers, PMs, and AI agents.

AI2SQL is an AI-powered SQL assistant that generates, explains, optimizes, fixes, formats and runs SQL against your live database schema, with read-only, audited connections and multi-database support.

ClearML is an AI infrastructure platform that provides a three-layer solution — an Infrastructure Control Plane, an AI Development Center, and a GenAI App Engine — to manage GPU resources, accelerate model development, and deploy GenAI/LLM workloads at enterprise scale.

Massed Compute is a cloud GPU provider offering on‑demand GPUs, bare‑metal servers, and clustered GPU infrastructure with a programmatic API and SDKs for machine learning, rendering, HPC, and data analysis. It emphasizes fast provisioning, enterprise NVIDIA SKUs, and compliance (SOC 2, GDPR, HIPAA).

PDF.co provides a low-code REST API for automating PDF conversion, editing, extraction, classification, and AI-powered invoice parsing, aimed at developers and automation workflows.

Modal is a production-grade AI infrastructure platform that lets developers run inference, training, batch processing, and secure sandboxes with fast cold starts, instant autoscaling, and a Python-first developer experience.
