Etonify is an open-source VPN client for Android, built with Flutter and etonify-core, a maintained fork of sing-box. It manages subscriptions, server selection, DNS and traffic routing.
The application does not provide VPN servers. You need your own server or a subscription from a provider.

The source version comes from pubspec.yaml; the bundled core version comes from libbox.provenance.json. The source tree may contain changes that are not yet published. Check Releases for available APKs and release notes.
Android is the supported release platform. Other Flutter platform directories do not imply supported desktop or iOS builds.
- Download an APK for your device from Releases and install it.
- Add a subscription or import a server configuration.
- Select a server or an automatic selection group.
- Start the connection and approve Android's VPN permission request.
In-app updates are available under About > Updates. Use the menu in that section to select Stable or Beta. Beta includes prereleases intended for testing; the version displayed in the app may not contain a “beta” suffix.
- Connections: Android VPN through TUN, local HTTP/SOCKS proxy, or both.
- Subscriptions: import from a URL, file, clipboard, QR code or supported deep link; refresh profiles and view provider-supplied traffic and expiry information.
- Servers: manual selection, automatic selection groups, proxy chains and latency testing through the proxy connection.
- Routing: per-app routing, local network bypass, traffic rules and local rule sets.
- DNS: direct and proxied resolvers, encrypted DNS options and AdGuard DNS filtering.
- Core settings: network strategy, connection timeouts, TCP keepalive and UDP/NAT controls. The section includes explanations, a first-visit notice and its own reset action. See Core settings.
- Diagnostics: connection logs and runtime information for troubleshooting.
Latency tests measure a request through the proxy, not ICMP ping. A missing result does not by itself establish whether a server works.
Import formats include server links, sing-box JSON, Xray JSON, Clash YAML and SIP008. Supported protocols include VLESS, VMess, Trojan, Shadowsocks, Hysteria/Hysteria2, TUIC, AnyTLS, NaiveProxy, HTTP and SOCKS. Compatibility depends on the protocol, transport and fields used in the configuration.
Importing an Xray or Clash profile does not mean every feature of its original core is supported. Etonify converts supported settings to its own sing-box configuration. See sing-box 1.14 compatibility for migration details.
WireGuard has not been supported since Etonify 0.3.1 because of problems with its operation in the client.
Multiplexing requires compatible server support. It is not automatically negotiated for every server, and sing-box multiplexing is not interchangeable with Xray Mux. Provider-supplied settings and manual overrides are explained in the core settings section.
- Send HWID to provider in General settings controls the global device-identification option for subscription requests. Individual subscriptions can also have saved consent. Review these settings before adding a subscription.
- Untrusted proxy certificates are a separate security setting. Enabling it bypasses certificate verification; it should not be a general fix for connection problems.
- Logs and screenshots can contain subscription URLs, server addresses, credentials or device identifiers. Check and redact attachments before sharing them, even if the application has already masked some fields.

The client CI uses Flutter 3.47.2 and JDK 21. Dart constraints are defined in pubspec.yaml, and Android build tools are pinned in the Gradle files. Rebuilding the core uses a separate toolchain recorded in ETONIFY_BASELINE.

The bundled AAR's source commit, version, toolchain and checksum are recorded in libbox.provenance.json. Do not infer the binary's source revision from the current submodule HEAD. See bundled core documentation for replacement requirements and CONTRIBUTING.md for contribution guidelines.
For bugs and suggestions, use the issue forms. Include the application version, device model, Android version and vendor software version, reproduction steps and relevant redacted logs. If the problem started after an update, mention the last working version.
