With the surge of AI, new applications are released every day. We hear buzzwords like "cloud-native" and "disruptive innovation" constantly. However, when you calm down and look at daily development, the tools that truly feel right are the ones that quietly and effectively solve specific problems.

We are constantly bombarded by popular tools—like new VS Code extensions or the latest JetBrains updates. But outside the spotlight, there are many tools that, while they may not be trending topics, solve specific pain points in our development workflow.

Today, I want to talk about a few tools from my private collection. They might not be famous, but once you use them, you’ll understand their value.

ServBay - The Cornerstone of Local Environment Management

Setting up a local development environment is definitely one of the biggest headaches for programmers.

The likes of XAMPP/MAMP from the early days can no longer keep up with the times, offering too little freedom in configuration. Everyone has rushed to embrace Docker. While Docker is indeed powerful, it can feel a bit heavy for scenarios where you just want to quickly run a local project or debug a script. Writing Dockerfiles, managing containers, and handling network issues can make a beginner break down in minutes.

Enter ServBay.

It isn’t just a simple integrated environment; it’s more like a dispatch center for local development services. It is fully featured and highly practical.

Multi-language, Multi-version Coexistence and One-Click Switching

This is ServBay’s strongest feature. You can install different versions of PHP, Node.js, Java, Python, Go, and even Rust development tools as easily as ordering from a menu.

For example, if you need to maintain an old legacy project using PHP 5.6 and a new project using PHP 8.2 simultaneously, ServBay allows them to run locally at the same time without interference. You no longer need to modify system variables or use complex version management tools just to switch environments.

One-Click Installation of Common Services

Besides programming languages, databases and cache services are standard for a local dev environment. ServBay supports one-click installation of SQL databases like MySQL, MariaDB, and PostgreSQL, as well as NoSQL tools like Redis, MongoDB, and Memcached.

The "One-Click Redis" feature is particularly useful, saving you the trouble of compiling it yourself or pulling Docker images. You can use it in seconds with a single click. It also supports local AI deployment, making it very suitable for "Vibe Coding."

Performance and Resource Usage

It is based on the Caddy server and includes performance optimizations for various services. It starts up quickly and uses fewer resources than running a pile of Docker containers—saving a bit of electricity and reducing fan noise is always a good thing.

In short, if you don’t want to configure a local environment manually but feel Docker is overkill for certain scenarios, ServBay provides a "just right" solution.

Zed - The Code Editor That Flies

Is VS Code good? Of course, it is. It has a powerful ecosystem and comprehensive features. But its problem is becoming increasingly obvious: it’s getting slow. As you install more plugins and project files get larger, you often feel noticeable lag and latency.

Zed is a new work from the former Atom editor team. Its core selling point is just one word: Fast.

Opening a large file of several hundred megabytes, Zed is almost instant, while VS Code might still be loading. Its interface response, code rendering, and file search speeds are top-tier. This is because it is written in Rust under the hood and puts a lot of effort into GPU acceleration.

Of course, Zed’s ecosystem is not yet comparable to VS Code, and the number of plugins is limited. But for developers who pursue extreme performance and like a pure coding experience, it is definitely worth a try. Especially for frontend development or scenarios where you frequently handle large files, Zed’s speed advantage will leave a deep impression.

GitButler - Making Git Operations More Intuitive

Git is powerful, but many of its concepts (like stash, rebase) are still confusing for many people. We often just want to save a few lines of code as a commit, but we have to switch back and forth between different branches.

GitButler offers a brand-new approach. It supports handling multiple unrelated tasks within the workspace simultaneously. You can package code changes belonging to the same task (even if distributed across different files) into a "virtual branch," and finally turn this virtual branch into a real Git commit.

This process is visual—you just need to drag and drop code blocks to organize changes. It weakens the constraints of traditional branches, allowing developers to focus more on the project itself rather than worrying about selecting branches. For developers who frequently need to fix bugs and develop new features simultaneously, this tool can greatly reduce the complexity of Git operations.

Focalboard - Open Source, Self-Hosted Project Management

Team collaboration cannot exist without project management tools. Trello, Jira, and Notion are all good choices, but they are either expensive or too complex for small teams. Plus, using them means all your project data lives on someone else’s server.

Focalboard is an open-source alternative that you can think of as a combination of Trello and Notion. It provides various views like Kanban boards, tables, and calendars, offering enough functionality for daily use. The most attractive point is that you can easily self-host it on your own server, keeping your data completely under your control—safe and secure.

Sentry - Find Code Errors Before Users Complain

"I’m getting an error here, the page won’t open." Do you get PTSD when you hear this sentence?

Don’t worry, Sentry is here. Sentry is an error tracking system that captures error information the moment an exception occurs in a project (whether frontend or backend). It captures detailed stack traces, user operation paths, and device environments, and then sends out a notification.

This allows you to intervene and fix issues proactively before users even notice them. It supports almost all mainstream programming languages and frameworks, and integration is quite simple. For any online project, Sentry is a crucial part of ensuring stability.

Datadog - Full-Stack Monitoring Platform

If Sentry focuses on errors, Datadog cares about everything. It is a full-stack monitoring platform that integrates all observability data, including system logs, metrics, and application performance monitoring (APM).

You can use it to monitor server CPU usage, view slow database queries, and trace the complete path of an API request between microservices. It aggregates monitoring information that would otherwise be scattered in various places, giving developers a global understanding of the system’s health. If there is one drawback, it’s the price—it can be expensive. However, for teams maintaining complex systems, the value it provides is immense.

Subframe & FlatIcon - Design Resources to Boost Efficiency

Finally, I recommend two non-typical development tools that are especially useful for full-stack or frontend developers.

• Subframe: A tool that uses AI to assist in generating UI components. You just need to describe the component you want in text (e.g., "a user card containing an avatar, username, and follow button"), and it can quickly generate the corresponding React/Tailwind CSS code. It saves a lot of time writing styles when you need to quickly build prototypes or dashboard interfaces.
• FlatIcon: One of the largest free vector icon libraries. Projects always need various small icons; designing them yourself is unrealistic, and searching everywhere is time-consuming. FlatIcon provides a massive amount of high-quality icons in various formats and even supports online color modification, which is very convenient.

Final Thoughts

The value of a tool lies in solving problems, not chasing trends. The tools introduced today may never be as universally known as VS Code, but they all offer superior solutions in their respective fields for us developers.

I hope this list brings you some new inspiration. If you have any hidden gem tools in your collection, feel free to share and discuss them in the comments!
