Termius vs ConnectBot in one line
ConnectBot is a free, open-source, Android-only SSH client that has done the basics reliably for years. Termius is a modern, cross-platform client (Android, iOS, and desktop) with sync, SFTP, and a polished UI — but its best features are paid. If you want free, open source, and simple on Android, ConnectBot still works. If you want one client across your phone and computer, Termius fits. And if you want a modern app with an AI assistant on a free tier, TermAI sits between the two. Here's the honest breakdown.
Side by side
| ConnectBot | Termius | TermAI | |
|---|---|---|---|
| Price | Free (open source) | Free tier; Pro ~$9.99/mo | Free tier; Pro $2.99/mo |
| Platforms | Android only | Android, iOS, desktop | Android, iOS |
| Host/key sync | ❌ local only | ✅ (Pro) | ✅ (Pro) |
| SFTP | ❌ | ✅ (Pro) | ✅ |
| AI assistant | ❌ | Paid add-on | ✅ free tier |
| Tailscale | ❌ | ❌ | ✅ built-in |
| UI | Dated | Modern | Modern |
ConnectBot — free, open source, simple
ConnectBot is the veteran free Android SSH client. Its strengths are exactly what you'd expect from open source: it's genuinely free, needs no account, and does SSH reliably without trying to upsell you. It's also lightweight and privacy-friendly — nothing leaves your device. The downsides are age: no cloud sync, no integrated SFTP file manager, no AI, and a UI that looks like the Android of a decade ago. It still gets occasional maintenance, but it isn't gaining modern features.
Best for: Android users who want free, open source, and no account.
Trade-off: Android only, no sync, no SFTP, dated UI.
Termius — modern and cross-platform
Termius is the polished, cross-platform option: it syncs hosts, keys, and snippets across Android, iOS, and desktop, has integrated SFTP, and a modern interface. The catch is the price model — sync, SFTP, and its AI assistant live behind the Pro subscription (~$9.99/month), whereas ConnectBot gives you the basics for free. If you bounce between a phone and a laptop and want one client, that sync is the draw.
Best for: people who want one polished client across phone and desktop.
Trade-off: best features are paid. See Termius alternatives.
TermAI — the modern middle: free tier with AI
Most people comparing ConnectBot and Termius are really choosing between "free and basic" and "modern but paid." TermAI is the option in between: it's actively developed and modern like Termius, but its free tier includes real SSH, SFTP, built-in Tailscale, and an AI assistant (5 AI calls/day) — the thing neither ConnectBot nor free Termius gives you. Describe a task in plain language and it suggests the command, grounded in your live server, with a confirmation before anything destructive runs.
Tapping Run drops the command into the live session — the AI is part of the workflow, not a separate chat.
How to pick
- Free, open source, Android, no account → ConnectBot
- One polished client across phone + desktop → Termius
- Modern app with AI + Tailscale on a free tier → TermAI
FAQ
Is ConnectBot still good in 2026?
Yes for basic, free SSH on Android — it's reliable and open source. But it lacks sync, SFTP, and AI, and its UI is dated, so it's not the pick if you want modern conveniences.
Is Termius better than ConnectBot?
Termius is more capable and cross-platform, but its best features are paid; ConnectBot is fully free and open source. It depends on whether you value sync and polish over zero cost.
Is there a free alternative to both with AI?
TermAI's free tier includes an AI assistant, real SSH/SFTP, and built-in Tailscale across iOS and Android — free where Termius charges and modern where ConnectBot is bare.
Is ConnectBot open source?
Yes. ConnectBot is open source and free, with no account required — one of its main appeals.
