Free Microsoft Office & Adobe Alternatives (2026 Guide)

Imagine opening a document that looks and works like Microsoft Word, a spreadsheet that behaves like Excel, and a photo editor with Photoshop's menus and shortcuts - and never paying a subscription for any of them. Not a free trial. Not a watered-down web version. Real desktop software you download once and keep forever.

That is exactly what a developer named Brandon Thomas is building. His project, ArtCraft, has released a growing lineup of free, open-source "clean-room" rebuilds of the world's most expensive software: Microsoft Office, Adobe's creative apps, and even AutoCAD. This guide breaks down every tool, what it replaces, who it is for, and how to get it.

What is happening, in plain words

ArtCraft started as a small project making open tools for artists. Then Thomas, frustrated by Adobe's subscription prices and cancellation fees, decided to rebuild the big expensive apps from scratch - without copying anyone's code. "Clean room" just means the code is original: the apps copy the look and behavior, not the source code.

The twist is how fast this happened. Thomas built these apps in Rust (a fast, modern programming language) with heavy help from Claude, Anthropic's AI coding assistant. The first batch - seven Adobe-style apps - launched around the end of September 2026. The Microsoft Office-style apps followed in early October 2026. The public response has been enormous: PhotoCraft, the Photoshop alternative, alone collected over 23,000 stars in its first week or so.

Why "free forever" is actually true here

A lot of "free" software comes with catches: trials, watermarks, accounts, or features locked behind a paywall. ArtCraft is different because of its licenses:

• The code is open source under Apache 2.0 and MIT licenses. That means anyone can read it, download it, share it, and even modify it.
• No subscription, no account, no activation. You download the installer and the app is yours.
• You can keep old versions forever. Even if the project changed direction tomorrow, the code you downloaded keeps working.

The project plans to make money separately by selling access to its own AI image and video models, not by charging for the apps. The apps themselves stay free.

The Microsoft Office replacements

WordCraft - the free Microsoft Word alternative

Replaces: Microsoft Word

WordCraft is an open-source word processor that looks and feels like Word. It has the familiar ribbon interface at the top, plus styles, tables, Track Changes, comments, references, and mail merge - the features most people actually use day to day. It reads and writes real .docx files, so documents you make can be opened in Word, Google Docs, or anywhere else.

Use cases: Writing reports, assignments, CVs, letters, and any document you would normally write in Word. Great for students who need .docx compatibility for school submissions.

Benefits: No Microsoft 365 subscription, works offline, and your files stay in the standard .docx format so you are never locked in.

Current status: Pre-alpha. The developer estimates it covers about 87% of Word's ribbon commands and 62% of Word's overall features. Everyday writing is close to ready, but complex documents with charts, SmartArt, or embedded objects are not supported yet. Real-world .docx compatibility testing is still getting started.

GridCraft - the free Microsoft Excel alternative

Replaces: Microsoft Excel

GridCraft is the spreadsheet of the family, and on paper it is the most complete of the three Office apps. It supports more than 500 functions, PivotTables, dynamic formulas, LET and LAMBDA (advanced formula tools), charts, and reads and writes real .xlsx files.

Use cases: Budgets, expense trackers, grade sheets, sales dashboards, data analysis, and anything you would build in Excel. If you are a student learning spreadsheets, this is a free place to practice the exact same skills.

Benefits: Free forever, no Microsoft account needed, and it speaks the same .xlsx file language as Excel so your files work everywhere.

Current status: Pre-alpha but moving fast. It covers roughly 89% of Excel's ribbon commands and about 93% of worksheet functions - though independent estimates suggest it handles around 65% of what an advanced Excel power user needs. Fine for everyday spreadsheets; heavy financial models with macros and add-ins are not there yet.

DeckCraft - the free Microsoft PowerPoint alternative

Replaces: Microsoft PowerPoint

DeckCraft is the presentation builder. It offers themes, layouts, images, tables, charts, transitions, and animations, and it can open and save PowerPoint files.

Use cases: Class presentations, business pitches, slideshows, and lecture decks. If you can build it in PowerPoint, the goal is that you will be able to build it here.

Benefits: No subscription for the occasional presentation, runs on every major operating system, and your slides stay in PowerPoint-compatible format.

Current status: Alpha - the earliest of the three. The developer puts it at about 79% of PowerPoint's features and 80% of the way to a first alpha release. Expect rough edges.

CADCraft - the free AutoCAD-style alternative

Replaces: AutoCAD (2D drafting)

CADCraft is ArtCraft's take on professional drafting software in the style of AutoCAD - the industry standard for architects, engineers, and designers, and one of the most expensive subscriptions in software.

Use cases: Floor plans, technical drawings, 2D layouts, and learning CAD skills without paying for an AutoCAD license.

Benefits: A free path into CAD for students and hobbyists. AutoCAD's price puts it out of reach for most beginners; a free alternative changes who gets to learn these skills.

Current status: Listed in the ArtCraft Launcher catalog. Details are thinner than for the Office apps, so treat it as one to watch.

The Adobe replacements

Before the Office apps, ArtCraft released seven apps aimed at Adobe's Creative Cloud:

• PhotoCraft replaces Photoshop - photo editing with Photoshop-style panels, menus, and shortcuts. It opens real PSD files.
• VectorCraft replaces Illustrator - vector graphics, logos, and illustrations.
• FilmCraft replaces Premiere Pro - video editing.
• LightCraft replaces Lightroom - photo organizing and color grading.
• EffectCraft replaces After Effects - motion graphics and visual effects.
• DesignCraft replaces InDesign - page layouts, brochures, magazines.
• PdfCraft (also called PrintCraft) replaces Acrobat - working with PDF files.

Use cases: Photo editing, graphic design, video editing for YouTube, and school or freelance creative projects - all without Adobe's monthly bill.

Benefits: The big one is familiarity. Older free tools like GIMP work fine but force you to relearn everything. These apps deliberately copy the menus, panels, and shortcuts you already know, so switching costs you almost no learning time.

Coming soon: SoundCraft, a rebuild of Pro Tools-style audio production software for music and podcast editing, is listed as coming soon.

Current status: Early alpha across the board. The developer's own estimates for PhotoCraft (the furthest along): about 86% of mainstream features, roughly 65% of test PSD files rendering pixel-perfect, and only about 25-35% of the way to "a professional could switch for daily work." Users have reported bugs in basic functions. Promising, but not production-ready.

The secret weapon: AI can press every button

Here is the part that makes these apps genuinely different from every free alternative before them. Every button and menu item in these apps is a named command that an AI agent can trigger. They ship with a command-line interface and an MCP (Model Context Protocol) server - in plain words, a standard way for AI assistants like Claude to operate the software directly.

Concretely, you can connect GridCraft to Claude with one terminal command:

claude mcp add gridcraft -- gridcraft-cli mcp

After that, you can ask Claude to build your spreadsheet for you - formatting, formulas, charts - and it presses the buttons itself. The same idea applies across the suite: describe the photo edit, the slide deck, or the document, and the AI drives the app. No other free Office or Adobe alternative is built AI-native like this.

Where they run

One installer headache these apps skip: they run just about everywhere.

• Windows, macOS, and Linux - native desktop apps (not slow web wrappers).
• Web browser - WebAssembly builds run right in a browser tab.
• BSD is also supported for the Office apps.

Each app's repository published installers for all of these at launch. You are not tied to one operating system to use them.

The honest reality check

This is exciting, but go in with open eyes:

1. They are early. Pre-alpha and alpha mean bugs, crashes, and missing features. Do not replace the tools you depend on for paid client work yet.
2. Feature parity is a work in progress. The developer first claimed full parity within a month, then walked it back to "months, not years" for 99%. The Office apps sit around 60-80% feature coverage depending on the app.
3. Complex files may not survive the round trip. WordCraft drops charts, SmartArt, and embedded objects; real-world .docx compatibility testing has barely started. Test with copies of important files, not originals.

The right way to think about these apps today: download them, try them on non-critical work, and watch them improve at unusual speed. AI-assisted development is shipping updates far faster than traditional open-source projects.

How to download and try them

1. Go to ArtCraft's apps page (getartcraft.com/apps).
2. Pick your app: WordCraft, GridCraft, DeckCraft, CADCraft, PhotoCraft, VectorCraft, FilmCraft, LightCraft, EffectCraft, DesignCraft, or PdfCraft.
3. Choose the installer for your system: Windows, macOS, Linux, or the browser version.
4. Download, install, and open it - no account, no key, no payment.
5. Try opening one of your real files (.docx, .xlsx, .pptx, .psd) and see how it handles it.

If you are technical, you can also build the apps from source, since all the code is public.

Frequently asked questions

Is this legal?

Yes. These are clean-room reimplementations: original code written from scratch that mimics behavior, without using Microsoft's or Adobe's source code. They are not affiliated with Microsoft or Adobe, and their icons and artwork differ.

Is it really free? What is the catch?

There is no catch on the apps themselves. The Apache 2.0 and MIT licenses let you use, share, and modify the software freely, forever. The project plans separate paid AI services, but the apps stay free.

Will it open my existing Word, Excel, and PowerPoint files?

That is the goal, and basic files already open. But compatibility testing is early - charts, SmartArt, macros, and complex formatting may not survive. Always test with a copy first.

Do I need an internet connection?

No. These are real desktop apps that work offline. Only the browser versions need the internet, obviously.

Should I cancel my Microsoft 365 or Adobe subscription today?

Not yet, unless your needs are very basic. Think of these as a free second toolkit to learn and experiment with while they mature. For students and beginners, though, they may already be enough to skip paying entirely.

Who is behind this?

Developer Brandon Thomas, a software engineer with about 15 years of experience (roughly a decade in Rust), building with Anthropic's Claude Opus 5.5. He started the project after frustration with Adobe's subscription and cancellation fees - fees serious enough that the US government sued Adobe over them in 2024, ending in a $150 million settlement in 2026.

The bottom line

For decades, "free alternative" meant learning a whole new app that looked nothing like the software everyone else used. ArtCraft flips that: free apps that look like Word, work like Excel, open your PSDs, and can even be driven by AI. They are unfinished, but they are real, they are yours to keep, and they are improving at a pace the software world has never seen. Download them, kick the tires, and keep an eye on this project - it might be the beginning of the end of the software subscription era.
