Developer Tools Tools

opencode zen is a curated, “ready-to-use” gateway of tested models optimized for coding agents. It integrates as an optional provider within opencode, offering pay-as-you-go access to top models (e.g. GPT-5, Claude, Grok) with no lock-in.

Select the exact parts of a repository and compile them into one clean text file for ChatGPT and Claude or Gemini. MashuPack is built for browser-based AI workflows where file-count limits, upload friction, and messy context assembly keep getting in the way. It makes code context portable, intentional, and easy to control.

Finding a good domain is half the battle. tldx is a blazing-fast, concurrent CLI tool that generates and checks domain availability in bulk via RDAP. Mix keywords, prefixes/suffixes, or regex, and stream results to stdout, JSON, or CSV. Plus, tldx includes an MCP server, empowering AI agents (like Claude) to brainstorm and verify domains for you automatically! Install via Homebrew (brew install tldx). Say goodbye to rate-limits and legacy whois parsing. 100% Free & Open Source in Go.

"OpenRouter + Intelligence" LLMTest helps devs and vibe coders automatically: ✅ Pick better models for AI-powered features (faster, cheaper, better, sometimes all 3 combined) ↪️ Automatically add fallbacks when LLM providers fail (API is overloaded or JSON format isn't respected) All through one single API and MCP functions so you can just tell Claude or Codex to optimize everything.

ModelHub is a native macOS menu bar app for developers working with local LLMs. It helps you discover models from Hugging Face, download the right local build, manage your model library, and use Hugging Face models with Ollama, MLX, LM Studio, llama.cpp, and the tools you already have without bouncing between browser tabs, terminal commands, model cards, and local folders. Ollama, MLX, and LM Studio are great tools. ModelHub is the missing discovery and management layer around them.

Your Claude Code session shouldn't die when Anthropic goes down or your plan runs out. Edgee Fallback Models keeps coding assistants running by routing to alternative models like Kimi K2.6, Gemma, GLM, or Qwen when Claude is unavailable, rate-limited, or just too expensive. Or one-click fallback to your own Bedrock, Vertex, or Azure account. Same Claude Code, different backend, zero code changes. Built for teams that can't afford to stop shipping.

1.Auto scan, 2.Eyedropper, or 3.Element-based? Meet the 4th approach: Selection-based pixel analysis. This Chrome extension sees what users see, delivering reliable contrast ratios for complex visuals. No more relying solely on tedious manual picking. Just drag and know.

Every MCP server you have configured injects its tool definitions into your context window on every single message — whether you use it that session or not. Vibedock sits in your macOS menu bar and lets you toggle MCPs on and off in one click. It automatically kills and relaunches your Claude sessions so the change actually takes effect.

Antigravity CLI brings multi-step reasoning, multi-file editing, tool calling, and persistent history to the terminal. Optimised for SSH sessions and keyboard-first workflows. For developers who live in the command line.

AGG Labs SSO is a streamlined, fully-featured OIDC Identity Provider designed for developers who want complete control over their authentication layer. Forget bloated enterprise solutions. We provide seamless integration for your applications, featuring silent SSO, strict PKCE flows, granular active session management, device tracking, and an intuitive developer portal. Standardize your access control and build a unified ecosystem with an auth system that respects your architecture.

Today, many agents read keys and sensitive info from dotenv files, configs, or memory. One bad prompt or compromised tool can drain your wallet, API bill, or private data. DCP makes agents safe for real work: your wallets and API keys stay encrypted on your own machine. Give each agent only the scopes it needs; it asks, you approve from Telegram or App. Daily budgets, logs, and instant revoke keep you in control. Open source, non-custodial, and works with Claude, Cursor, OpenClaw, and Hermes.

A local-first pipeline automation app for developers powered by AI, running natively on your machine. Think of it as a local Zapier or n8n, built specifically for developers who want to chain shell commands, AI calls, HTTP requests, and file operations into reusable pipelines then trigger them on a schedule, on a file change, or via webhook.

SuprSend now ships six AI-native interfaces for notification infrastructure. MCP Server with 24 tools in your IDE, CLI for notification config as code versioned in Git, Agent Skills so AI knows your schemas instead of hallucinating your API, an AI Copilot inside the dashboard, a Slack Agent to trigger and debug from Slack, and a Claude Extension. Works across Cursor, Claude, Windsurf, and Slack. Used by 500+ companies. Free tier available.

Local Area Network discovery tool with an interactive Terminal User Interface (TUI) written in Go. Discover, explore, and understand your LAN in an intuitive way. Knock Knock.. who's there? 🚪

Shuffle’s Design CLI lets you generate landing pages and redesign websites directly from your terminal. Automate design workflows, leverage multiple AI models, and ship better websites faster.

TestSprite generates and runs end-to-end tests for your app, autonomously. For backend, we can now generate complex integration tests with dynamic variables, auto-cleanup, and Data Flow debugging. For frontend, we now send a fleet of parallel AI agents to explore your app first — clicking through every feature like real users, then feeding results into testing. We're the first to do this. 3.0 also adds auto-heal for UI drift, auto-auth for regression, and a CLI for Claude Code, Codex users.

The production control plane for AI agents. Run agents like production servers: isolated, observable, and controlled. Firecracker microVMs with sub-200ms boot.

TongueType is a macOS voice dictation app powered by Whisper AI running locally on Apple Silicon. No cloud, no accounts, no subscriptions. Hold a key, speak, release. Your words appear. Supports 12 languages and audio file transcription. TongueType gives you a configurable press-to-talk hotkey, audio and video file transcription, and configurable post-processing rules. It's customizable and fun (try Rainbow Mode!) and it's built to be the fastest dictation workflow possible.

CatchAll is a web search API that builds structured datasets from the open web. Submit a query, and it scans thousands of web pages, validates every result, and returns clean, deduplicated records — not a ranked list of links, but a dataset of real-world events, ready for workflows and pipelines.

Give your AI agent a product flow to record. Slideshot drives your web app through MCP, captures the walkthrough, and returns a polished demo video and GIF with zooms, cursor motion, and custom intro animation. No manual recording or editing.

Google Antigravity 2.0 is a standalone desktop app for orchestrating multiple AI agents in parallel, with scheduled background tasks, subagent workflows, and native integrations with AI Studio, Firebase, and Android. Built for developers building production apps.
