Top 10 Free Tools Every Developer Should Be Using

Visual Studio Code

Visual Studio Code (VS Code) continues to be the go to editor for millions of developers and for good reason. It’s fast, lightweight, and flexible enough to fit almost any workflow.

Why Developers Love It

VS Code is more than just a simple text editor. It brings powerful features to your fingertips without bogging down performance.
Lightweight and Efficient: Loads fast and runs smoothly even on modest machines
Intelligent Editing: Built in support for syntax highlighting, IntelliSense, and real time debugging
Cross Platform: Works seamlessly across Windows, macOS, and Linux

Expand with Extensions

One of VS Code’s greatest strengths is its vibrant and extensive extension ecosystem.
Thousands of Extensions: Whether you’re working in JavaScript, Python, Go, or Rust there’s an extension for that
Customizable Workflows: Tailor your development experience with themes, linters, containers, and more
Dev Tools Built In: Popular integrations like ESLint, Prettier, Docker, and Live Server are just a click away

Built In Tools for Productive Dev Cycles

VS Code eliminates the need to switch to external applications for common development tasks.
Git Integration: Commit changes, resolve conflicts, and push updates without leaving the editor
Integrated Terminal: Access your command line directly inside the app
Robust Debugging: Step through code, set breakpoints, and view call stacks for efficient troubleshooting

Whether you’re writing your first lines of code or working on enterprise scale applications, Visual Studio Code offers everything you need to build smarter and faster.

Postman

Postman has become the go to tool for developers working with APIs and for good reason. It strips away the complexity of testing endpoints with code and replaces it with a slick, visual interface that gets results fast. Whether you’re building or consuming APIs, Postman lets you hit the ground running.

Collections are where the magic happens. You can group requests, store variables in environments, and write test scripts that run automatically. That means less repetition, more automation, and far fewer chances to screw up in a live environment. Debugging APIs no longer feels like wrestling with a wall of cURL commands.

If you’re still manually testing every endpoint, you’re wasting time. Postman saves hours that add up fast especially in teams or when testing complicated workflows. It doesn’t just speed up development; it straight up makes it easier to get things right.

Docker

Docker does one thing really well: makes your app portable. You package everything it needs code, libraries, environment into a container, and it just runs. Doesn’t matter if it’s your laptop, the staging server, or production. That consistency pays off fast, especially when you’re working in a team or bouncing between machines.

For devs building microservices or systems that need to scale cleanly, Docker is a game changer. You can spin up isolated services in seconds, test without messing up your main environment, and push updates without breaking stuff. It’s clean, repeatable, and tough to replace once you’ve gone all in.

Bottom line: if you build, break, and rebuild often Docker belongs in your stack.

GitHub

Version control isn’t optional it’s essential. GitHub remains the industry default for tracking code, collaborating with teams, and pushing clean releases. It’s more than just a repo host; it’s the backbone of nearly every modern software project.

Free private repositories make it just as accessible to indie devs and small teams as it is to enterprise giants. Built in tools like project boards, Actions for CI/CD workflows, and issue tracking turn GitHub into a full blown dev command center. Need continuous deployment or automated testing right in your repo? It’s baked in.

Add to that a massive open source community and countless third party integrations, and you’ve got a platform that doesn’t just store your code it accelerates it. If you’re writing code in 2024 and not using GitHub, you’re missing the foundation everyone else is building on.

Figma

Figma has become the go to tool for design and dev collaboration and for good reason. It eliminates the old back and forth of emailing static design files or hunting for the right asset folder. Everything lives in the browser, no installs, no setup headaches. Open a shared file, and you’ve got real time visibility into what’s being designed, tweaked, or finalized.

For developers, the inspect mode is where Figma shines. CSS values, spacing, and font details are all there, ready to copy. No more guessing margin sizes or pixel aligning by eye. Exporting assets is just as simple click, download, done. It’s fast, it’s precise, and it’s built for handoff without friction.

Whether you’re prototyping a new product or refining a button’s border radius, Figma makes the workflow cleaner and a lot less painful.

Swagger UI / OpenAPI

api documentation

APIs are the connective tissue of modern software, and Swagger UI makes documenting them almost effortless. With a clean, auto generated interface from your OpenAPI specs, you can share interactive API docs that actually make sense to humans not just machines. Teams don’t need to bounce between spec files, code, and wikis anymore it’s one source of truth, live in the browser.

The real kicker? You can test endpoints right there on the page. No extra tools. No guessing. Swagger turns what used to be a slow back and forth between frontend, backend, and QA into a direct line of action.

For dev teams juggling multiple services, Swagger UI takes a ton of friction out of the loop. It’s not flashy. It’s not noisy. But it gets the job done and that’s exactly what you want when things need to move fast and keep working.

Notion

Staying organized matters more than ever and Notion makes that simple. Whether you’re logging ideas, stashing code snippets, or tracking project tasks, it’s all in one place. It’s clean, fast, and flexible enough to handle everything from daily to dos to complex team wikis.

Notion’s biggest win? Its markdown style editing that feels natural for devs. You don’t need to learn another strange syntax or fight with formatting. Just type, drag, and rearrange. Need to document an internal API or build a shareable knowledge base? That’s a five minute job in Notion.

Teams run entire workflows here. Solo devs use it like a second brain. Either way, it scales with you without cluttering your process. If your current notes are a messy folder of .txt files, Notion might save your sanity.

Tmux

Tmux is a must have for developers who live in the terminal. Simple yet powerful, this open source terminal multiplexer allows you to level up your command line productivity without adding bloat to your workflow.

Why Developers Love Tmux

Run multiple terminal sessions simultaneously: Tmux allows you to split your screen into multiple panes, each running its own shell.
Persistent sessions: You can start a session, disconnect (even over SSH), and pick up right where you left off later.
Ideal for remote work: Whether you’re coding on a server or bouncing between SSH sessions, Tmux makes context switching seamless.

Key Features at a Glance

Split screen workspaces: vertical and horizontal panes for multitasking
Session and window management: group terminal tasks efficiently
Works over SSH: keep your sessions alive even after disconnection
Customizable shortcuts: tailored for power users

Boosting CLI Based Workflows

For developers who prefer the keyboard over the mouse, Tmux is a game changer. Combine it with tools like Vim or Zsh, and you’ve got a lightning fast command line setup that minimizes distractions and maximizes throughput.

ESLint + Prettier

If you care about clean, readable code and you should then ESLint and Prettier are non negotiable. ESLint analyzes your code to catch potential errors and enforce coding standards. Prettier takes care of the formatting. Combined, they remove all the debates about tabs vs. spaces and make every line look intentional.

This duo isn’t just about cosmetics. Messy, inconsistent syntax leads to bugs. Especially in larger teams or fast moving projects, little issues pile up fast. ESLint helps prevent that by flagging code smells early even before runtime. Prettier keeps everyone’s style in check, no matter who’s committing.

They plug into almost every major language and editor with minimal setup. Whether you’re in VS Code, WebStorm, or tucked into a Vim session, they just work. Set up a config file once, and your whole team’s codebase plays by the same rules.

Use them together, tweak the settings to match your style guide, and you’ll spend less time arguing about code and more time writing it.
