Top 5 Open Source Tools You Should Try in 2025

In a world increasingly dominated by subscription-based software and closed ecosystems, open source tools remain a refreshing alternative. They provide transparency, flexibility, and community-driven development that many users—both technical and non-technical—appreciate. Whether you’re a developer, student, remote worker, or just a tech enthusiast, 2025 is shaping up to be a great year for free and open source software.

The open source community continues to push boundaries with tools that rival or surpass paid alternatives in functionality and innovation. Here are the top 5 open source tools in 2025 that are worth your time.

1. LibreOffice 24.2 – The Best Microsoft Office Alternative

Category: Productivity Suite
Why You Should Try It: LibreOffice has long been a favorite among open-source users, but the 2025 version (24.2) represents a major leap in performance, compatibility, and cloud integration.

LibreOffice now offers seamless collaboration tools, improved support for Microsoft Office formats (.docx, .xlsx, .pptx), and a sleeker, more modern UI. The Writer, Calc, and Impress modules—equivalents of Word, Excel, and PowerPoint—are not only fast but also feature-rich.

New features in 2025:

• Real-time document collaboration using Nextcloud integration

• Enhanced macro scripting support using Python and JavaScript

• Redesigned UI with optional tabbed layout for easier navigation

• Accessibility improvements and full dark mode compatibility

LibreOffice is perfect for students, freelancers, and businesses looking to escape expensive Office 365 subscriptions without losing core functionality.

2. GIMP 3.0 – The Photoshop Alternative Gets a Modern Makeover

Category: Image Editing
Why You Should Try It: GIMP (GNU Image Manipulation Program) has always been powerful, but its learning curve and UI quirks kept some users away. That changes in 2025 with the highly anticipated GIMP 3.0 release.

This version features:

• GTK3-based interface for better performance and look

• Non-destructive editing support (finally!)

• Smart object layer support for better Photoshop compatibility

• Enhanced plugin system and one-click installation of community plugins

• AI-powered upscaling and background removal via integrated modules

GIMP is now a solid contender not only for casual image editing but also for professional graphic design work, especially for users who want to avoid Adobe’s subscription model. Whether you’re editing photos, creating digital art, or making YouTube thumbnails, GIMP 3.0 delivers.

3. OBS Studio 31 – Streaming and Recording Made Easy

Category: Multimedia / Live Streaming
Why You Should Try It: OBS Studio (Open Broadcaster Software) is the gold standard for video recording and live streaming. Used by gamers, teachers, content creators, and professionals alike, OBS remains completely free and open source—with no watermarks, ads, or restrictions.

In its latest 2025 version:

• GPU efficiency has been vastly improved for lower system load

• Stream presets for YouTube, Twitch, and Kick are optimized for 4K streaming

• Plugin store integration for faster setup and new features

• Virtual camera improvements for better video call integration

• Support for AV1 and HEVC encoding for better video compression

Even if you’re not a streamer, OBS is incredibly useful for screen recording, tutorial creation, or capturing webinars. Paired with open source video editors like Kdenlive, it’s a powerful production suite.

4. VSCodium – Visual Studio Code Without the Telemetry

Category: Code Editor / IDE
Why You Should Try It: Microsoft’s Visual Studio Code is a beloved code editor—but not everyone is comfortable with the telemetry and data collection baked into the default build. That’s where VSCodium comes in.

VSCodium is a de-branded, telemetry-free version of VS Code, built from the exact same source code. It’s maintained by the open source community and updated in lockstep with the official builds.

Highlights:

• Same extensions and theme compatibility as VS Code

• No tracking or user analytics

• Supports all modern programming languages (Python, JavaScript, C++, Rust, etc.)

• Works perfectly with GitHub, Docker, and remote development tools

For developers who want power, speed, and privacy, VSCodium is the perfect editor.

Bonus: It’s portable and lightweight enough to run from a USB stick or cloud folder.

5. Bitwarden – The Secure Password Manager That Respects Your Privacy

Category: Cybersecurity / Productivity
Why You Should Try It: In an age of increasing data breaches and phishing attacks, password managers are no longer optional—they’re essential. Bitwarden is an open source alternative to services like LastPass and 1Password and is widely praised for its security, simplicity, and affordability.

What makes Bitwarden a standout in 2025:

• End-to-end encryption with zero-knowledge architecture

• Cross-platform apps (Windows, macOS, Linux, Android, iOS, web)

• Self-hosting options for full control

• Password generator, 2FA, and secure notes

• Free tier that covers all essential features, including sync

The latest release includes biometric login, emergency access, passkey support, and integration with browsers like Brave and Firefox.

If you’re serious about protecting your online identity, Bitwarden is one of the best tools available—open source or not.

Why Open Source Tools Matter More Than Ever

Open source isn’t just about free software—it’s about freedom, transparency, and community trust. With growing concerns over surveillance, data monetization, and vendor lock-in, using open source tools ensures:

• Auditability: Anyone can inspect the source code for malicious behavior.

• Customizability: Tools can be tweaked to your exact needs.

• Security: Community eyes often find vulnerabilities faster than corporate teams.

• Longevity: Projects don’t disappear because a company pivots or shuts down.

In 2025, the line between open source and commercial software is blurrier than ever. Some open tools outperform their paid rivals in polish, speed, and usability.

Honorable Mentions

Here are a few more open source tools worth exploring this year:

• Kdenlive – A non-linear video editor great for YouTubers and filmmakers.

• Audacity – Lightweight audio editing for podcasts and music.

• Thunderbird – A full-featured email client with calendar and task integration.

• Zotero – A reference manager for students, researchers, and writers.

• Syncthing – Peer-to-peer file syncing without the cloud.
