Software Engineering Tools

Now that AI writes the code, what should engineers learn? Understanding code still matters, and understanding code means learning how a senior engineer thinks. diff-tour turns a git diff into a tour you step through with → and ←: what the change is for, where to look, what a senior asks (what if it runs twice? can it roll back?), what must be fixed and what is a nit, and where they'd say "wait", asked as questions so you guess first. Runs on your AI coding CLI. Read-only, open source.

Revix AI scans your repo, generates its own pattern and architecture rules, and reviews every pull request against them. It keeps learning as the repo changes. Each comment names its rule and is labeled by intent and severity. Free for public repos.

A flexible, modern approach to the popular git-flow branching model. Download the CLI tool to get started with a better Git workflow: brew install git-flow-next

Whiteboard is a canvas for thoughtful software development. Critique interactive visualizations, diffs, and agent trajectories, all from one interface.

Running multiple coding agents shouldn’t mean becoming their project manager. BAND lets them work together. Connect agents across your existing development tools and give them a shared workspace to coordinate tasks, exchange context, and hand off work without you playing middleman. See what every agent is doing, step in when decisions need your judgment, and scale agentic development across teams. Your agents stay in their existing tools while BAND handles the teamwork.

RunInfra Coding Plans give your coding agent fast open models for a flat monthly price, starting at $10. Use GLM 5.3, DeepSeek V4.1 Flash, Qwen3.8 27B and more inside Claude Code, Codex, OpenCode, Cline, Droid or Grok Build. Setup takes one prompt: paste it into your agent, approve sign-in, done. Session-aware routing hits cache up to 99.5% of the time, so your plan goes further. Zero data retention, no training on prompts, SOC 2 Type II.

/dev/null started as a live stream from the JetBrains office. On Oct 15, 2026, Nuno Maduro, Brent Roose, Matthieu Napoli, and Pauline Vos built a social network for web developers from scratch in 48 hours, in the open. Sign in with GitHub, share code snippets, like, reply, etc, etc! Hundreds of you sent PRs. Laravel’s Taylor Otwell stopped by mid-stream (“Laravel forever”), and Vercel’s Guillermo Rauch called it “really well done.” Thank you for watching, sharing, and roasting us.

A native Mac file browser with Git built in: every repo's branch, status and changes in one window. New since launch, in 60 releases: • AI commit messages, built in or with your own key • Branches, stash, merge and rebase, no terminal • Dashboards for each repo and your whole workspace • Issues & PRs from GitHub, GitLab, Codeberg, Bitbucket • Repo Trust: see what a repo auto-runs before you open it • Cleaning: reclaim GBs of rebuildable dev junk. 100% native SwiftUI. No Electron. macOS 15+.

CodeCrab is your local-first AI code review assistant. This version connects seamlessly with GitHub, GitLab, Claude, Codex, Cursor, and Copilot CLI. Drill into every exact change with our new Finding Deep-Dive & Follow-Up feature to inspect, question, and refine AI suggestions without leaving your workflow.

Observability built for NestJS by its creator. Add the SDK and a key, and every request shows up as a trace of your own controllers, providers and queries, with errors, jobs, logs and runtime metrics alongside. Free up to 300k events a month.

Kerno v1 is our biggest upgrade yet, a complete AI Backend QA Engineer. It maps your codebase, learns how your app works, and gets sharper with every run. It now tests your whole backend, from full user flows and live security checks to background jobs, queues, MCP servers and AWS serverless. Bugs get caught inside your agent's session before you open a PR, then re-checked on every PR in CI.

Tiden verifies your coding agents built what you actually asked for. Most checks run inside the session that wrote the code, so the tests agree with it by construction. Tiden keeps your intent as requirements that branch and merge like code, and checks every change against that record. The verdict comes from tests run in your environment; no model grades the diff. You decide what merges, and production errors trace back to the release. Works beside Claude Code, Cursor, Codex and Copilot.

A Claude Code mod that puts Edgee in your terminal. Keep your Claude plan, switch your session to any of 200+ models in one keystroke, and see live what compression and routing save you. Same conversation, same context. Two commands to install.

Staffcoder is a hands-on coding platform where developers practice real engineering work instead of algorithm puzzles. Choose from 1000+ challenges across 39 learning paths, covering React, Next.js, Django, Spring Boot, Docker, Kubernetes, AI agents, and more. Every challenge runs in a full browser IDE with a real terminal, file system, and live preview, so there is nothing to install. Pick a stack, open a challenge, and build. Free to start.

Most tunnels hand you a new URL every time. tunnl.gg gives you the same one: connect as [email protected] and your SSH key becomes your identity, so your public HTTPS URL never changes. Register a webhook or OAuth callback once and forget it. Nothing to install, no account, works on any machine with SSH, with a QR code and live request log in your terminal. Free to use. Pro adds your own subdomains, no time limits and a request inspector. Open-source (MIT) server.

* Fully compatible with agentic coding tools: Claude Code, Codex, OpenCode, Cursor, Pi, Cline, and many more. Full multi-modal support. * Hundreds of open- and closed-weight models. Create routing rule presets or use our Auto routing algorithms. * Providers compete dynamically on price for every prompt, offering the lowest marginal cost. * Sign up for free with email, first 500 users get $20 of free inference. Receive 20% of referred fees as free inference, 10% for second-level referrals.

3 years after launching as an AWS serverless monitoring tool, KloudMate returns to PH as a full-stack, AI-powered Observability & Agentic SRE-Ops platform. It unifies metrics, logs, traces, and more, while KloudMate AI helps teams investigate incidents, find root causes, and resolve tickets. From dashboards to instant answers, KloudMate is built for modern, distributed systems. KloudMate AI Modules - Assistant (Answers), Builder (Dashboards, Alarms), Investigator (RCA), Docs (Documentation).

CodeCrab is a native desktop app that reviews Pull Requests in seconds using your local CLIs. 100% client-side — your code never leaves your machine.

OrgComputers is a shared workspace for your AI agents. Projects, context and tools in one place, so Claude Code, Cursor and Codex start with what your team already knows.

Bentomux is a calm desktop app for running coding agents side by side: project workspaces, persistent split-pane terminals, live agent state and approvals.

A coding agent you can talk to — in your terminal or on your phone. 1. Voice, both ways. Read one sentence (~10 sec) to enroll your voice. Consent-first; the delete key is yours. 2. 404 models on one account — Claude, GPT, Gemini, DeepSeek and more. OpenAI- and Anthropic-compatible. 3. MIT open source: github.com/yukihamada/sente Japan-built: Tokyo region, JPY billing. Honest limits: metered, not unlimited. Monthly credits; top up if you go over. We never clone a voice that isn't yours.
