4 Open-Source Android Keyboards That Outshine Gboard

In a world where Google’s Gboard has become the default keyboard for hundreds of millions of Android users, it’s easy to forget that you have real alternatives—especially open-source ones that respect your privacy, give you unlimited customization, and often deliver a smoother, more thoughtful typing experience.

Gboard is undeniably polished, but it comes with trade-offs: constant internet pings, aggressive data collection, cloud-dependent glide typing, forced “smart” features you can’t fully disable, and a growing list of non-keyboard bloat (stickers, GIFs, translation pop-ups, etc.). For power users, privacy enthusiasts, and anyone who just wants a clean, fast, distraction-free typing experience, open-source keyboards have quietly become superior in many ways.

Here are four open-source Android keyboards that, in 2025, genuinely outshine Gboard in day-to-day use.

1. HeliBoard (The new king of the hill)

If someone told you in 2023 that a fork of the long-dead OpenBoard would become the most loved keyboard on Android by 2025, most people would have laughed. Yet here we are.

HeliBoard (formerly known as “OpenBoard reborn”) is everything Gboard should have been:

• 100 % offline – dictionary, autocorrect, glide typing, everything works without a single network request

• Glide typing that rivals or beats Gboard in accuracy (thanks to an improved gesture engine based on the original AOSP gesture library + community patches)

• Built-in clipboard manager with history and pinning (no need for third-party clipboards)

• Per-language layout switching, height adjustment, number row toggle, arrow keys, Ctrl key, and even a full PC-style layout if you want it

• User dictionary that syncs via Syncthing or any file-based solution (no Google account needed)

• Material You theming that actually follows your wallpaper colors perfectly

• Zero telemetry, zero ads, zero bloat

What makes HeliBoard special is the insane pace of development. The lead maintainer (Helium314) and dozens of contributors ship new features almost weekly. In 2025 you get:

• Voice typing that works completely offline (using Vosk or Whisper.cpp models you download yourself)

• Proper multilingual prediction without sending your text to Google

• One-handed mode that actually feels natural

• Customizable swipe actions (swipe left on backspace = delete word, swipe right on space = cursor control, etc.)

If you only try one keyboard from this list, make it HeliBoard. Most people who switch never go back.

Latest version as of Nov 2025: 1.9.x

2. FlorisBoard – The customization monster

FlorisBoard is the keyboard for people who treat their phone like a desktop.

Think of it as a full IDE for typing:

• Smartbar that you can fully customize: clipboard, one-handed mode toggle, voice input, emoji, number row, media keys (play/pause, next track), even shortcuts to apps or Tasker tasks

• Per-app theme switching (dark theme in WhatsApp, light in Notes, etc.)

• Emoji 15.1 support with skin-tone memory and recent emoji grid

• Advanced auto-correction engine that learns from your corrections and never reverts

• Landscape layout that actually looks good (dual thumb-optimized split layout option)

• Built-in calculator in the smartbar (yes, really)

• N-gram based next-word prediction that works offline and improves over time

FlorisBoard also has the best theming engine on Android. You can create themes with gradients, key borders, custom fonts, animated press effects, and even different popup key styles. Power users on XDA and Reddit have made themes that look like iOS, Windows 11, old BlackBerry, or cyberpunk neon—whatever you want.

The only downside? Glide typing (called “Glide”) is still labeled beta in 2025, though many users report it’s already smoother than Gboard on one-handed use.

If you love tweaking every pixel, FlorisBoard is pure joy.

3. Unexpected Keyboard – The best for tablets and foldables

Originally created for the PinePhone, Unexpected Keyboard was ported to Android and quickly became the favorite of anyone using a large screen.

Why it shines:

• Thumb-optimized layout specifically designed for 7–13 inch screens

• Split layout in landscape that feels natural (not just a stretched phone layout like Gboard)

• Resizable and movable (yes, you can drag the entire keyboard around like on old Windows Mobile devices)

• Built-in mouse/trackpad mode – hold a key and drag to move the cursor precisely (perfect for Fold/Tablet users)

• Extremely low latency – many users report it feels “snappier” than even the AOSP keyboard

Unexpected Keyboard looks simple at first, but it’s deceptively powerful. It has no autocorrect or prediction by design (you can add them via third-party plugins), which makes it blazing fast and distraction-free for coders, writers, and anyone who hates being “corrected.”

If you own a Galaxy Z Fold, Pixel Fold, OnePlus Open, or any Android tablet, try this one immediately. You’ll wonder why Google never made a proper tablet keyboard.

4. AnySoftKeyboard – The veteran that refuses to die

AnySoftKeyboard (ASK) has been around since the Cupcake days (2009!) and is still receiving monthly updates in 2025.

It may not have the flashiest UI, but it wins on pure reliability and features:

• Supports over 80 languages with proper dictionaries (more than Gboard in some cases)

• Gesture typing that works offline (added in 2022 and continuously improved)

• Power-saving mode that disables animations and prediction when battery is low

• Top-number row that can be toggled with a single swipe

• Physical keyboard support that’s better than anything else (great for Bluetooth keyboards)

• Incognito mode that disables all learning and history with one tap

• Unique “swipe selection” mode for precise cursor control

ASK’s biggest strength is stability. If you want a keyboard that “just works” on even the most obscure ROMs and devices, this is it.

Honorable Mentions (worth checking out)

• Thumb-Key – A single-thumb, 9-key minimalist keyboard for extreme one-handed use

• Simple Keyboard – Ultra-lightweight (under 2 MB), perfect for low-end devices

• Hacker's Keyboard – Still the only keyboard with real Ctrl, Alt, Esc, and function keys (essential for Termux users)

Why open-source keyboards win in 2025

1. Privacy – No data leaves your device unless you explicitly allow it.

2. Speed – No cloud latency, no background syncing, no bloatware processes.

3. Customization – From key borders to swipe actions, you control everything.

4. Offline everything – Glide, voice, prediction, spellcheck—all work on a plane or in the wilderness.

5. Community-driven – Bugs get fixed in days, not months. Features you want actually get added.

How to switch (and make it painless)

1. Install your chosen keyboard from F-Droid or GitHub.

2. Go to Settings → System → Languages & input → On-screen keyboard → Manage keyboards → Enable the new one.

3. Long-press in any text field → Input method → Select new keyboard.

4. (Optional) Use “OpenBoard User Dictionary Sync” or manually export/import your Gboard dictionary to keep your personal words.

Most users report that after 24–48 hours of muscle memory adjustment, they type faster and with fewer errors than they ever did on Gboard.

Final thoughts

Gboard is the safe, corporate choice. But in 2025, safe doesn’t have to mean compromised.

HeliBoard, FlorisBoard, Unexpected Keyboard, and AnySoftKeyboard aren’t just “good for open-source”—they are objectively better for millions of users who value privacy, performance, and control.
