16 free tools & services that any developer should use

This article is a 2018 revised version of my original article

Free tools & services for any developer

I want to thank all the service providers and developers that allowed their product to be used for free. What is the best way to repay them? advertising.

I will share the most useful free & open source tools that I use in my work & home environment. The tools can be used in any env/ language/ framework/ project. If you are a devops in a large corporation or a freelance developer this article should be a good start.

Probably you know about most of the tools already, hopefully today you’ll hear about a new one.

I will skip chat clients like Slack, services such as Stack Overflow, twitter, YouTube and other Google products. I use most of them, everything in my life starts in a Spreadsheet. Inbox & google docs are awesome for prototyping, ideas, formulas, project docs, working alone or shared across the team.

Class A — Productivity+ for devs, ops, QA, IT

Visual Studio CodeCode editor, closer to an IDE than the rest I would say. I used it only for the last few weeks, but it became #1 right away, for me it replaced Atom/Sublime/Notepad. Visual Studio works with any language and config files (json, xml, ini …). It replaced MonoDevelop for Unity3D, I do TDD in Go, code in Java, C# etc.

I was very skeptic at first, being a Microsoft product, but I threw everything I had and it handled it perfectly. It just runs fast and across platforms. I will still use my PHPStorm (webstorm) for large projects though (for now). It has a very good learning curve, one of it’s features is the KeyMap, I use my Intellij keyboard shortcuts in VSCode, how cool is that?

Trello — Task list, to do list, shopping list, to visit places list, stuff to do with the kids, notepad for ideas, task management for small projects/teams, bug tracker, feature planning, should I go on? Trello runs across all platforms and the free tier is good enough. Also it has many integrations & plugins.

GetShareXScreenshot and Screecast of your dekstop/window/region. I use it for bug reports, screenshots, examples, record “how to …”, etc. It’s similar to Snagit/Jing but better (is open source). Records video or gif, has scriptable actions like auto upload to imgur after a screenshot and a lot of other features. For Linux I use a mix of Shutter and Ubuntu screenshot builtin tools.

Toggl — Track your time spent working. Time is a valuable currency, so I keep tracking how I spend it. Toggl has a powerful idle detection (the measured time will be more accurate), browser, desktop and mobile clients. Supports multiple projects and even generates reports (good for freelancers/remote workers). It’s all about calculating the resources invested in a project vs the gains.—algorithms. If TopCoder is too serious for you, and CodeCombat too childish, you will love Codewars. It is all about keeping your brain in shape. If you are stuck at work doing the same algorithms over and over or fixing legacy code all day you need some good problems that can be solved in a few minutes. Supports multiple levels of difficulty and most programming languages. It’s all about improving your programming skills.

SourceTree — git client. I usually use bash for git commands, but when I need an UI I use SourceTree. It’s cross platform and easy to understand, we used it to teach non-technical team members how to use git. If you are looking for something more simple & friendlier check GitHub for desktop.

Storage — I use Bitbucket for free unlimited private git repositories and github for open source ones and gists (code snippets). Dropbox/Google drive for other resources and backblazeto host images/videos.

Vimium - This tool will improve your browsing speed, searching in history/bookmarks, closing tabs, opening links you name it. It follows the Vim mantra, everything done with the keyboard. Works on Chrome and Firefox.


  • GitLab - I will soon move to Gitlab and most probably it will replace BitBucket (for me) because of their rich interchangeability and devops features.

  • If you want to practice for your coding technical interviews and system design I strongly recommend. It has the best quality of UI,UX,problems, solutions and tests.

  • UTime — chrome extension to convert UnixTimestamps/dates

  • Postman — Web API tester, it’s simple awesome. You can save&share templates and the paid tier supports JS automatic tests!

  • Bash for windows — from Git for Windows, MobaXterm (if you connect often to remote servers) or Native Win10 Bash

  • Fiddler(windows) a very rich proxy for web development. I use it to debug web apps (their requests). CharlesProxy is better and works for iOS too but it is not free.

Class M — Media

Gimp2 — It is more than enough for my graphical needs. I use it for photos editing, creating simple GFX for prototypes, resize/transform images and create collages (different sizes, transparency etc). It took me a long while to get used to it (coming from Fireworks), but was worth it. Tip: activate Single Window Mode.

Canva — When you need social media posters, banners, collages, headers or logo and you lack a designer, Canva Team will help you. It has a good free tier for small projects and it’s awesome. It has thousands of pre-made templates and photos that you can use freely in your commercial projects.

Piktochart— One word, infographics. Piktochart knows all about them. It doesn’t have such a great free tier, but it’s an awesome start.

SoundCloud —Say it, you cannot work w/o music. If you do not care about latest tracks with half naked women, and you just want to listen to some good old music SoundCloud is all you need. It has even technical podcasts, or science like StarTalk Radio.


  • Inkscape — Open source vectorial drawings, it has more features than you would think.

Thanks for reading! I hope that you found something useful around here.

My additions.


  • GitKraken: Another Git GUI client, happens to be less annoying than the others. Free for open source, early startups, and non-commercial use.
  • VirtualBox: The defacto standard for development VMs
  • Vagrant: Automate VM setup. Combined with SaltStack a very powerful tool.
  • RealtimeBoard: Like a whiteboard in the cloud, except better in every way. Not free, but has a free edition. You can just drag & drop stuff like PowerPoint presentations on it, zoom and scroll pretty much infinitely, etc.
  • Freepik: So far my favorite source of vector icons and such for presentations, architectural diagrams, etc.
  • Slack: Basically the communication tool of choice for technical teams and projects nowadays.
  • Discord: Quite a lot like Slack, but different. More aimed for non-professional use, but works for business use quite decently as well.
  • Paletton: Color scheme designer
  • IFTTT: If This Then That - automate various actions and applications easily.
  • Zapier: A bit similar to IFTTT, but .. different.
  • Font Awesome: When you need icons for your web apps (and with some work other apps).
  • Google Fonts: Quite possibly the best online font library for web use.
  • Insomnia: REST client. Like Postman, but with less bugs, and overall feels better.
  • SSL Server Test: Identify SSL configuration errors.
  • SendinBlue: Transactional email service - send 300 emails/day for free. Much more than enough for various monitoring notifications etc., especially if combined with e.g. Google Groups.

For Windows:

  • ConEmu: Better terminal for Windows
  • Cygwin: Bring a bunch of the GNU utilities and other tools from Linux to Windows environments
  • Greenshot: Simple and good screenshotting tool.
  • WinMerge: Excellent diff tool.

I've used both Insomnia and Postman and simply put, Insomnia is to Postman what VSCode is to Visual Studio.

Postman's power comes in its ability to do more advanced prototyping and API development stuff and "project" or collections of API calls that are exportable and sharable.

Insomnia, on the other hand, is more strictly for interfacing with existing APIs, and as a result doesn't really have feature parity with Postman, but that's not really a bad thing. Not everyone needs or wants the advanced features of Postman and just needs something to poke at an API with. For that, Insomnia works great.

Winmerge is great. BeyondCompare ( is my go-to, however. Commercial, but worth the money. And cross-platform too!

Great list you created. Some of them I didn't know but I will give it a go :D is definitely a great app that I use quite a few times when creating svgs or design mockups for a template.

Another great app is Dash unfortunately its only available for mac and ios. The app is meant to be your go to place for all documentation. You can add a bunch of them (python, javascript, bootstrap and much much more), what makes the app great is that you can use it offline so you can always check up on documentation.

Do you know Zeal ? It's multiplatform.

Dash look nice but how do you share that with your team? Especially the non-mac users. Most probably they have the same problems as you and vice versa.

Maybe something like gitlab code snippets with IDE plugins would work, I never tried it.

fabiorosado profile image
Fabio Rosado

Yeah sharing with the team might be an issue, the documentation is downloaded into ~Library/Application Support/Dash/Docset but the file is a .docset extension so maybe you would need to open it with some other program.

Its a work around but very ugly one haha Perhaps devdoc plugin is a good idea as Giorgos suggested (i havent tried that one yet tho)

There is devdoc plug in for Chrome which is identical, and velocity for windows!

I use Blue light filter utilities like Flux on my laptop and Twilight on mobile.

Especially recommended for developers who spent lots of time in front of bright displays. It took some time for me to get used to these, but now I can't work at night if these filters are not on.

Apologies if I diverted from the intent of the post.

bgadrian profile image
Adrian B.G.

Nice, if you need to work at night maybe is a good addition to the toolbox.

I tried this technique on the tablet, when reading, and it felt wrong, I couldn't watch it for more then a few minutes.

Is true that the white light may interfere with your sleep, it will trick the brain that is daylight. To fix this I just stay away from the display at night :D.

Something I've been using for a little bit now is, which is a browser based version of Inkscape/Gimp. I mostly enjoy the flexibility of their cloud storage.

bgadrian profile image
Adrian B.G.

Sorry to hear that, I haven't used it in a while. True their quality of service and katas is not the greatest but the "battle" feeling is great.

For more CS and Math problems I recommend, and for interviews

Other more Gamified alternatives are and, also good for non-tech people that want to switch to a dev-related position and need something fun to do while learning. These two I recommend after

I forgot to add - Online free diagrams. I use it to explain things (like on the whiteboard), UML and Architecture diagrams, it has even the AWS/GCP icons.

(not so free) It has a limited free tier, is like Skype/Hangouts but it has a special feature: a drawing whiteboard, which is great for collaboration talks.

Wanted to add Flatirons Fuse to the list. Flatirons Fuse is an embeddable CSV import tool that makes importing data to your website fast, easy, and painless.

This is so helpful! Thank you so much for sharing!

Glad I could help, I like to be more efficient and freebies, so I combined them.

I've used VS Code and I personally prefer it over Atom and Sublime.

Another awesome free tool you can use if you're on Windows is CMDER. It is a Windows command line interface that uses Linux commands (think ls for list files/directories instead of dir for Windows). Plus, you can have several consoles open at once (great if you're running a few node servers to test your projects).

All in all, thank you for sharing this amazing resource. I appreciate it.

Hey, thanks for your reply!

For windows there are more ways to install a "bash", with the Windows Subsytem or with Emulators like the one from git for windows.

I recommend to have as close as possible to bash emulator otherwise it will be a bigger difference between the env in which you code and the production one, which will lead to subtle problems along the way. Also bash and unix tools are very powerful, you can get away with writing code inside your app for simple mondene tasks.

Beware, VS code is open-source, but the binaries are far from it !

Probably because of the IntelliSense "magic" library.

Thanks so much for this extremely comprehensive list! I'll definitely try out a few of these services.

As for the comments, I second GitKraken and Dash -- great tools! For time tracker, I prefer It seems that it has more features than Toggl and it's free as well.

I'd also like to add to this list, as it is a good place for prototyping.

I haven't included any Web development specific tool on purpose. That will be another post.

It's a hard one to make, it wouldn't fit in a book but I will try to focus on specific areas and needs. Most of the articles I found are for UI/UX, I will focus on the technical part.

A suggestion to add to the Class A list:

fakeJSON: A mock API for rapid development. Even comes with test data.

I think is too specific for this list, but I will add a similar one in my next related article specific for Web Developers.

Thanks for the list - great!
I’d also recommend - most likely every app/system/platform/database/whatever... when you need it. You can use it e.g. for testing your code on different platforms, quick building temporary databases (or sometimes even the permanent ones ;) etc.
Very useful tool for me (development of plug-ins to Jira and Confluence).

I actually started a Docker series on my blog, any feedback is appreciated.

Although Docker is free and increased my productivity by a lot (especially for local dev setups of projects), as you can see my list is more user-friendly, and not so technical. I left it out deliberately, but now thinking about it maybe it was a mistake.
