HexDroid is a free and open source IRC client for Android. It provides a clean, modern interface while supporting the features users expect from a desktop client — including IRCv3 capabilities, SASL authentication, TLS encryption, bouncer support, DCC file transfers, and an array of commands.

Requirements: Android 8.0 (API 26) or higher  ·  License: GPLv3

• Multi-network — connect to multiple servers simultaneously, each with independent nick, SASL, TLS, autojoin, and encoding settings
• Bouncer support supports ZNC and soju. Discover and clone profiles when connecting without a network profile.
• IRCv3 — 40+ capabilities including chathistory, away-notify, server-time, echo-message, draft/typing, MONITOR, bouncer-specific caps, and more
• Security — TOFU certificate pinning, SASL (PLAIN / SCRAM-SHA-256 / EXTERNAL), client certificates, Android Keystore credential storage
• irc:// and ircs:// — tapping IRC links in other apps opens HexDroid directly and connects to the target network and channel
• Localisation — Arabic, Chinese, Dutch, French, German, Italian, Japanese, Korean, Polish, Portuguese, Russian, Spanish, Turkish

• Material Design 3 with light, dark, and Matrix (green-on-black) themes
• Adjustable font family (Open Sans, Inter, Monospace, custom TTF/OTF) and size, separately for UI and chat
• Inline image and video link previews
• ASCII art rendering with auto-sized MOTD display
• mIRC colour rendering with 99-colour picker + ANSI colour rendering
• Nick @ autocomplete and /command completion with inline hint chips
• Channel op panel: topic, key, user limit; ban/quiet/except/invex list management
• IRCop tools panel (visible when umode +o): K/G/D/Z-line, Shun, Kill, SAJoin/SAPart, WALLOPS/GLOBOPS/LOCOPS, MOTD, Links, Uptime
• Per-network ignore list (case-insensitive; covers chat, notices, and DCC offers)
• Channel list with live search and typing indicators displayed per-buffer
• Lag indicator, swipe gestures, compact mode, intro tour for new users
• Backup/restore: network profiles and settings exported as JSON

HexDroid negotiates a comprehensive set of capabilities. All are enabled by default unless noted.

Automatic detection starting from UTF-8, with fallback to windows-1251, KOI8-R, ISO-8859-1/15, GB2312, Big5, Shift_JIS, EUC-JP, EUC-KR, and more. Manual override per network for legacy servers.

• DCC SEND and DCC CHAT with active, passive, and auto modes
• Secure DCC — SSEND and SCHAT for TLS-encrypted file transfers and chat sessions
• Configurable incoming port range and download folder
• Rich transfer progress cards with one-tap accept from notification
• Incoming DCC CHAT offers create a buffer immediately and deep-link from notification

The Play Store and IzzyOnDroid releases are reproducibly buildable — the APK produced from source matches the distributed binary byte-for-byte. The RB Status badge above links to the verification record. To verify locally:

./gradlew assembleRelease
# Compare the output APK against the downloaded release APK

No ads, analytics, crash reporters, or third-party SDKs. The app communicates only with the IRC servers you configure. All data is stored locally and deleted with the app. See the full privacy policy.

See CHANGELOG.md for the full version history.

Bug reports and pull requests are welcome. Please open an issue before submitting a PR for non-trivial changes.

Bug reports should include:
