Join public alpha testing!

Public alpha launches now!

February 12, 2026

We’re excited to announce the launch of Teleghosts - a software that bridges SimpleX chat with Telegram! We invite you to join the public alpha test and try teleghosts now!

To participate in public alpha you must have an active Telegram account. You will be running teleghosts on your local machine and you will have to create a Telegram bot for teleghosts on your own. Read the self-hosting guide to get started.

Note

Don’t have a Telegram account but still interested in the project? Stay tuned for the closed beta announcement where we will be testing our infrastructure, creating and managing Telegram bots for you!

The goal of public alpha is to get rid of all bugs in the bridge and finish work-in-progress features. You can help us tremandously by submitting error logs because most remaining bugs are caused by unhandled dynamic errors which we cannot handle until we see their runtime representation.

Below you will find a list of issues that we already know about.

Join our SimpleX group to submit your findings, get help, share suggestions, and participate in general discussions.

Known issues in current alphas

  • CRITICAL: simplex-cli leaks database password in ps output - fixed in alpha.3

  • CRITICAL: blacklisted users can still spam you with files - fixed in alpha.2

  • CRITICAL: no graceful shutdowns - all messages buffered in RAM are lost when you kill teleghosts or when the process exits due to an error.

  • CRITICAL: Your SimpleX profile preferences are not taken into account when sending media messages which causes the app to crash when you forbid some media file kinds - fixed in alpha.2

  • CRITICAL: Removing/changing SimpleX address leads to unrecoverable state that requires a full database wipe to be able to even relaunch the instance.

  • Not all spurious network failures are handled on Telegram side

  • Files for pending messages are not redownloaded after the app restarts

  • Unbounded file downloads may cause teleghosts + simplex-chat consume more than 256MB of RAM - fixed in alpha.2

  • Previews are not generated for Telegram GIFs

  • Telegram username updates are not bridged - fixed in alpha.2

  • The supplied --target argument is not validated to be a SimpleX address(not a one-time connection link) which prevents users from connecting to you with an app crash - fixed in alpha.2

  • Teleghosts admin doesn’t report an error when connecting to the bot profile without the --bot-mirror flag which usually causes an infinite message exchange loop between the admin and a target bot - fixed in alpha.2
