Open Source Alternative to Bilingua: LangX vs Bilingua (2026)

ComparisonOpen SourceLanguage Exchange

If you used Bilingua and are looking for an open source alternative to Bilingua, LangX is a free, open source (BSD-3) language exchange app for iOS, Android and the web that matches you with people who speak what you learn and learn what you speak. Bilingua itself appears to be gone: it has disappeared from both app stores and its website domain is parked, so anyone searching for a Bilingua alternative in 2026 needs a new home for their practice.

This page explains what happened to Bilingua, what it did well, and how LangX vs Bilingua compares for former users. We make LangX, so we will also point you to other apps like Bilingua where they fit you better.

What happened to Bilingua?

Bilingua was a language exchange app made by Creatella, a Singapore-based company, and first appeared on Google Play in March 2017. At the time of writing (September 2026):

  • According to the app tracker AppBrain, the Android app was removed from Google Play on June 4, 2023. Its last recorded update was in October 2018.
  • The iOS app’s App Store listing no longer loads.
  • The bilingua.io domain now shows a “domain for sale” page.

We have not found an official shutdown announcement, so we cannot give you a closing date beyond the Google Play removal. But with no app in either store, no updates since 2018 and the website gone, Bilingua is effectively closed.

If you still have an old copy of Bilingua installed, do not rely on it. An app with no updates since 2018 is unlikely to be maintained, and your matches are almost certainly inactive. Move your practice somewhere that is still being developed.

What Bilingua did well

Bilingua had a thoughtful idea at its core, and it is worth saying what people liked about it:

  • Matching on personality and interests. Instead of dropping you into a long list of profiles, Bilingua tried to pair you with people you would actually enjoy talking to. That is a real problem in language exchange: many conversations die after “hi, where are you from?”
  • A conversation helper. Its built-in bot, Shiro, suggested topics and questions based on your shared interests, and could suggest translations and corrections. That took some of the awkwardness out of the first few messages.
  • Light learning tools. A vocabulary list, a news feed, progress stats, games and quizzes made it feel more like a learning app than a chat app.
  • Free to use. Bilingua positioned itself as fun, free and effective, with languages like English, Chinese, Spanish, French and Japanese.
Bilingua: good at
  • Matching on personality and interests
  • Shiro suggested topics, translations and corrections
  • Vocabulary list, news feed, progress stats, games and quizzes
  • Free to use
Bilingua: watch out for
  • Removed from Google Play on June 4, 2023
  • No updates since October 2018
  • Text-first chat
  • Closed source, so it vanished with the company

If those were the parts you valued, look for an app that helps you start conversations and keeps them going, not just one with a big profile list.

Where LangX fits for former Bilingua users

LangX is not a copy of Bilingua, and it does not have a chatbot. What it does have is a focus on making each conversation teach you something.

Every match is a real exchange

On LangX you only see people who speak the language you are learning and are learning a language you speak. That means the person you write to has a reason to write back. Bilingua’s interest matching tackled the same problem from a different angle: both try to avoid dead-end conversations.

Corrections from real people, unlimited

Instead of an assistant suggesting fixes, on LangX your partner holds any message and corrects it. Corrections are unlimited on every plan, including Free, because they are the part of an exchange that actually teaches.

A real person, not a bot, fixes your sentence On LangX your partner holds any message and corrects it right in the chat. Corrections are unlimited on every plan, Free included. Example screen from the LangX app. Names and numbers are demonstration data.

Translation inside the chat

If you leaned on Shiro’s translations, LangX has translation built into the chat, so you can check a word without leaving the conversation. The Free plan includes 20 translations per rolling 24 hours; Pro has 1,000.

Voice messages and read-aloud

Bilingua was text-first. On LangX you can send voice messages to practice pronunciation, send photos to show what you mean, and have any message read aloud.

Streaks, tokens and leaderboards

Bilingua’s games kept people coming back. LangX uses daily streaks, LangX Tokens (an in-app point for talking and correcting, not money) and leaderboards to do a similar job.

Open source, so it cannot quietly vanish

This is the biggest lesson from Bilingua. When a closed app shuts down, it is gone. LangX’s app and API are open source under BSD-3 on GitHub, and anyone can host their own instance. That does not guarantee LangX will last forever, but the code cannot disappear with a company. For people looking for an open source alternative to Bilingua, this is the point.

Honest limits

  • Calls on the web only for now on LangX; they are coming to the iPhone and Android apps.
  • No conversation bot. LangX Copilot, private AI feedback on your own messages, is coming later for Pro, but it is not available yet.
  • A smaller community than the biggest exchange apps, so some language pairs have fewer people.
  • The free plan caps new conversations at 5 per rolling 24 hours. Replies and corrections are never capped. The plans page has the details.

Who should pick which?

Since Bilingua is no longer available, the real question is which Bilingua alternative suits you:

  • You liked Bilingua’s calm, one-to-one chats and want corrections and translation built in: try LangX. It is a free Bilingua alternative with no ads.
  • You want live voice or video calls: Tandem or Lingbe will suit you better.
  • You liked the social, feed-style side: HelloTalk has a public feed alongside chat.
  • You want structured lessons plus some native-speaker feedback: a course app like Busuu fits better than any exchange app.
