Best Developer Tools products of the week October 19, 2026

withHuman

A open-source human approval layer for AI Agents

withHuman is an approval layer for AI agents. It intercepts your agents' tool calls before they run, then applies rules that approve or deny routine actions automatically. Risky actions are sent to the right person on your team for review. It works with Claude Code, Codex, and agents built with LangGraph, Pydantic AI, and more, all through an open protocol called AAP. One set of rules covers every agent your company runs. The project is open source, and a hosted version is available. Use code PRODUCTHUNT to get 3 months of Scale free, valid until Friday.

heal.dev

Find bugs and vulnerabilities code review misses

Code review catches what’s wrong in a diff. Heal catches what breaks when the app runs. Heal learns how to run your application, builds a production-like sandbox with external services stubbed, then hunts for bugs, performance regressions, and runtime vulnerabilities users would hit. It reproduces every defect before reporting it, so you get real bugs to fix, not a backlog of AI-generated suspicions.

Harness by Autonomous

Every coding agent, every machine, one command center.

Harness is the open-source command center for coding agents. It brings together Claude Code at work, Codex at home, Hermes in the cloud, and every other agent on every machine, side by side. Use the native desktop app, type hn in your terminal, or use the iOS and Android apps to answer agents by voice. Everything is end-to-end encrypted. Then go beyond code with 49 harnesses for CAD, circuits, robots, games, and music. It is free on Mac and Linux.

Pomerado

Turn any website into an API; Faster & reliable browser use

Pomerado turns any website into an MCP or API in minutes. It opens up previously inaccessible sites like Google Flights, Zillow, Instacart, and legacy portals, turning them into native tools for your agents. That means you can automate everything that used to require manual work or a private integration. The open-source tool builds, hosts, authenticates, and maintains the integrations for you, so you can focus on building.

NitroStack

Build, test, and deploy MCP servers in one place

NitroStack is the full-stack platform for building production-ready MCP servers and AI apps. You get open-source TypeScript and Python SDKs for the core logic, NitroStack Studio for visual testing and debugging, NitroStack Workflow for orchestrating agent processes, and NitroStack Cloud for deployment. NitroStack Chat lets you ship a branded frontend without extra work. Auth, testing, deployment, and UI all stay in one workflow, so you do not need to patch together separate tools. Connect your finished servers to ChatGPT, Claude, or other AI clients. More than 80,000 MCP servers are already powered by NitroStack.

Craft Agents

The world's most powerful agents, with the UX they deserve

Craft Agents is fully open source and runs locally on your machine, so your data and API keys never leave it. You can bring any AI provider you like, including Claude, GPT, Gemini, or local models. Agents connect to the tools you already use, such as MCP, APIs, and local files, and they can act across all of them. Code diffs, data tables, diagrams, and live previews show up right inline, so you can review work without switching windows. You can turn results into persistent Pages, teach reusable Skills, and run Automations on a schedule. It all lives in a desktop interface that feels natural to work in.

Doneas

A daily accountability call with other entrepreneurs.

Doneas helps solo builders stay focused, accountable, and productive. Plan your week every Monday, join a 15-minute daily accountability call with five other builders, and track everything you ship on your public progress page. Plan less. Focus better. Ship more.

shim-cli

See what your coding agent sends. Mask what you can.

Shim is an open-source hook and local proxy that works with Claude Code, Codex, Copilot CLI, and VS Code. It keeps secrets and personal data out of tool results so the model never sees them, especially in Claude Code. The shim watch command shows you what a session sent and what it cost. There is no account to create and no telemetry to worry about, so you keep full visibility and privacy.

3AM Super Intelligence

Production incidents: investigated, proven, fixed

3AM is an AI on-call engineer built for systems you cannot rewrite. It identifies the root cause of an incident, rehearses the fix to make sure it is safe, and lets you resolve the issue with one tap in Slack. Everything runs from inside your network, so sensitive systems and data stay put while 3AM handles the work.

PasteKit

Format JSON, YAML & SQL privately

PasteKit lets you paste JSON, YAML, XML, SQL, CSV, or plain code and get formatted, validated output in an instant. It supports 58 formats, 48 converters, and a solid set of JSON tools such as diff, schema, repair, and jq. Everything runs in your browser, with a strict Content Security Policy keeping the whole process local, so the code or data you paste never leaves your machine.
