Basically a freemium Adobe Photoshop clone in your web browser !

Worth mentioning : Pixlr simpler

The Affinity Suite is my go to as a professionnal alternative suite to Adobe's one. Affinity Photo can replace Photoshop AND Lightroom simultaneously. Even tho I personnaly prefer Lightroom's workflow, I've manage the switch. You will need some re-learning as it's a bit different to Adobe photography softwares. Worth the attention as the license is not expensive at all.

If you're on macOS Pixelmator is a decent option with one time payment

If you want to go free and open source GIMP3 is the king ! In my opinion the UI is not as intuitive but you can install an open source plugin called PhotoGIMP that will change the interface of GIMP to looks more like Photoshop. Those combine gives you a really powerful free alternative to Photoshop.

If you use Photoshop as a painting app STOP, Krita is the way to go, free and open source you won't find better app.

If you're on iPad, Procreate seems to be the way to go

A professionnal solution for almost every device you can own and paint on !

For a Lightroom alternative this one is probably the closest as a full package. Easy to use, clean almost modern interface, amazing processing and snappy. It's a one time paiement that is profitable in only 2 years if you compare it with the subscription of Adobe Lightroom. It's probably the best RAW editing software I've found.

A free but really great option, probably the best bang for your bucks out there with a modern UI and a UX similar to Lightroom. You need to enter a OLYMPUS camera Serial Number to download the app but it's easy to find.

A more expensive solution but well known with tons of ressources, tutorials, presets etc... available online

You will need paid plugins to match Lightroom but still a great option.

A cheaper option but well worth buying

Cheap price, nice UI/UX, a bit laggy and slow, AI powered features

A really great option for mac users with both subscription or one-time payment !

A nice freemium option

GIMP is the open source alternative to Photoshop and Darktable the open source alternative to Lightroom. It's really powerful and complete but it does need a lot of relearn as the UI is not the more polished and intuitive. Still a great alternative and it's free so what are you waiting to download ? I would recommend this guide if you are used to use Lightroom https://mathiashueber.com/darktable-settings-for-lightroom-user/

Worth mentioning RawTherapee as a FOSS alternative to Lightroom but Darktable is in my opinion more fun to use even if it's slightly not as powerful and feature rich than Raw Therapee.

If you just want basic editing and just organized your pictures digiKam is a great option, you can also integrate it with darktable worflow and probably RAW Therapee too.

A lightweight free and open source RAW manipulation software worth trying.

Worth mentioning : Ansel

A light app to quickly view and sort RAW pictures similar to digiKam

The Affinity Suite is my go to as a professionnal alternative suite to Adobe's one. Affinity Publisher is in my opinion the only good alternative to Adobe InDesign. You can't open .indd but .imdl (InDesign MarkUp) which is really good to transition from your old project to the new software you just acquired.

QuarkXPress looks good but I never tried it.

Canva is a easy to use tool to replace many Adobe software. It is more oriented to template based creation and for semi professional or amator content creator. It is a freemium subscription based service.

Worth mentioning : Polotno A really cool online open source tool that might suits basics usage.

If you want to go free and open source Scribus unstable build on 1.7.X has a brand new UI with modern icons and layout. It can become a decent option even for new not-really-nerdy users. If you want/need stable build you can try Scribus 1.6.X but it have a really outdated UI. It can suites you if you do 2 flyers a year or a small book, but if you ever used InDesign go with Affinity Publisher.

The Affinity Suite is my go to as a professionnal alternative suite to Adobe's one. Affinity Designer is not perfect (yet), but in my use case completly replace Illustrator easily. It's intuitive and powerful. It can open .ai files with no to little issues.

A 100% free web based alternative.

For macOS users check Linearity Curve it's free, has a great UI and pretty powerful. As a paid alternative Pixelmator .

I haven't tested this new tool yet but promising one-time payment sofware.

If you want to go open source, Inkscape is your go to. Free and really powerful it will suite most of your needs. The UI is a bit outdated but it's still simple and intuitive. Give Inkscape a try :)

Worth mentioning : Dotgrid that is more basic.

A really great option for mac users

Another free and open source solution that is newer. It's still in early development (public alpha) but promising project.

A feature that Illustrator has is to vectorify bitmap images. This tool makes that too !

DaVinci Resolve is the top recommandation as a professional colorist tool. But now it is a complete video editing software with awesome features. Also the free version is almost identical to the paid one, so there is no reason not to try it. It will need some relearning as it's not like Premiere Pro but you can choose at the insatllation to have a more Premierish UI.

It even can replace Adobe After Effects with Blackmagic Design Fusion built-in and Adobe Audition with DaVinci Resolve Fairlight also built-in.

Only for mac user Final Cut Pro X is a good and powerful alternative to Premier Pro that I think I don't have to mention here as it is really popular.

For Windows users Corel VideoStudio is a great Final Cut alternative as it's inspired by that Apple UI.

A free online video editor, signing-up is required but no watermarks or paid feature

Worth mentioning : Omniclip Free and Open Source wide.video Freeware

For open source video editing Shotcut is my recommandation as it's powerful and quite simple to learn and use.

Worth mentioning: Nugget Video Editor

A more feature packed foss video editor

Worth mentioning : Olive Video Editor and Flowblade

This one is an AI tool to create (and edit) vertical shorts from long horizontal videos.

I said that DaVinci Resolve was a complete video editing software with awesome features ? Fusion is one of them. It's really professional and powerful. But as it's not layer based like Adobe After Effects you will need to relearn for a node based used.

Worth mentioning : NUKE

Natron is a really powerful and open source Adobe After Effects alternative. Like Blackmagic Design Fusion Natron is node-based so you'll need to learn how it works.

Probably one of the most advanced Free AfterEffects alternative for Motion Design

Worth mentioning : Jitter

The FOSS motion design app

Handbrake is a must-have if you're in the video industry. It's free and open source.

Based on OpenToonz

For drawing animation check Pencil2D For Stop-Motion animation look at Boats Animator

One time purchase for iPad only !
