Apple's Safari-native MCP server for web debugging agents

Safari MCP Server is Apple's safaridriver-based MCP server in Safari Technology Preview, giving compatible coding agents local access to Safari page content, console logs, network requests, screenshots, JavaScript evaluation, interactions, viewport controls, and accessibility/performance checks.

AI-native observability for multi-agent systems

Sazabi is an AI-native observability platform designed for fast-moving engineering teams building with LLMs and multi-agent systems. Backed by leaders from Vercel and LangChain, it provides multi-agent tracing, tool-call visualization, and latency analysis for complex agentic workflows. Focuses on helping developers debug the complete path of requests through interconnected agents and tool calls.

AI production engineer that auto-triages and fixes alerts

Sonarly is a YC W26-backed AI production engineer that autonomously triages production alerts, deduplicates them by root cause, and sends ready-to-merge pull request fixes. It connects to monitoring tools like Sentry and Datadog, analyzes alert patterns to identify the underlying issue, and generates code fixes or optimization recommendations. Built on Claude APIs, Sonarly reduces mean time to resolution for production incidents while minimizing alert fatigue for engineering teams.

Open-source observability and self-healing layer for AI agents

TraceRoot is a YC S25-backed open-source observability platform purpose-built for AI agents and LLM apps. It combines OpenTelemetry-compatible tracing with an agentic debugging runtime that reads your source code, correlates failures with recent commits, and proposes fix PRs automatically. BYOK support spans seven LLM providers; the entire stack runs self-hosted via Docker Compose, with TraceRoot Cloud available for managed deployments.

Debug Vue.js applications

Official browser DevTools extension for Vue.js providing deep inspection of component trees, reactive state, props, events, and slots. Includes Pinia/Vuex store debugging with time-travel, Vue Router inspection, performance timeline, and component highlighting. Works with Vue 2 and Vue 3. Available for Chrome and Firefox with standalone Electron app. Essential for debugging reactivity and understanding component hierarchies in Vue applications.

Next-gen browser and mobile testing

WebdriverIO is a progressive Node.js test automation framework built on the WebDriver and Chrome DevTools protocols. Provides an elegant, extensible API for web and mobile testing across every major browser and real devices. Supports Mocha, Jasmine, and Cucumber, ships with built-in service plugins (Selenium Standalone, Appium, visual regression), and scales from local smoke tests to distributed CI suites.

Z.ai desktop agentic development environment for GLM-5.2 coding

ZCode is Z.ai’s Agentic Development Environment for GLM-5.2 coding workflows. The desktop app combines a first-party coding agent, goal mode, model/provider setup, MCP server management, Git and terminal context, remote phone control, usage stats and safety confirmation modes so developers can plan, implement, review and iterate on long-running software tasks from one workspace.

Modern load testing for developers

k6 is an open-source load testing and performance testing tool developed by Grafana Labs. Developers write performance tests in JavaScript and execute them on a high-performance Go runtime capable of generating thousands of virtual users per machine. Features a CLI-first workflow, cloud-based test execution, and integrations with Grafana dashboards — making performance testing as accessible as writing unit tests.

Extremely fast Python type checker written in Rust

ty is an extremely fast Python type checker built in Rust by Astral, the team behind Ruff and uv.
