What is Ech0?

What it is

Ech0 is an open-source, self-hosted publishing platform for personal idea sharing. It lives in the open-source self-hosted microblog ecosystem, using Go and Vue, SQLite storage, and Markdown-based posts. The project is built as a lightweight personal microblog, not as a full social network or a team workspace. Ech0 is licensed under AGPL-3.0. It stays lightweight and easy to deploy.

The concrete problem it solves is the gap between quick note capture and public personal publishing. Memos can capture short thoughts, but Ech0 aims to publish those thoughts on a personal timeline. The timeline can be shared, discussed, and owned by the person running the server. It supports optional comments and sharing, so a private note space can become a public or semi-public feed without moving the data to a hosted service.

Key capabilities

  • Publishes short posts, links, and media from one clean interface.
  • Stores content with SQLite and SQLite3, using Markdown for note and post formatting.
  • Presents a personal microblog timeline that others can follow.
  • Supports optional comments and sharing for lightweight social interaction.
  • Provides RSS output for readers who want to follow the timeline without visiting the site.
  • Runs as a self-hosted server application built with Go and Vue.
  • Offers four interface locales, according to the repository badge.

Who uses it and how

  • Individuals run a personal public or semi-public timeline on their own domain.
  • Users publish quick thoughts, links, and media from a single interface.
  • Readers follow the timeline through RSS or shared links.
  • Visitors interact through optional comments when the owner enables them.
  • Self-hosters keep content ownership while using Ech0 as a lightweight social layer around personal notes.

Getting started

Deploy the Docker image sn0wl1n/ech0, or follow the official site and documentation at https://www.ech0.app/ and https://Ech0.app. Release information is available at https://lin-snow.github.io/Ech0/, and a preview instance is available at https://memo.vaaat.com/.

When to use it — and when not to

Use Ech0 when a person wants a self-hosted personal timeline for Markdown notes, links, media, RSS, and optional comments. Do not use it when a person needs a bi-directional Obsidian-style knowledge base, a team-first Notion-style collaborative workspace, or a pure memo tool with no publishing timeline. The repository is one year old, has six open issues, and expects the self-hoster to run the server and maintain the SQLite data.

Featured｜HelloGitHub

A self-hosted personal microblog where your timeline can be shared, discussed, and fully owned.

Tools like Memos are great for capturing quick thoughts. Ech0 is built for what comes next: publishing those ideas to a personal timeline that others can follow and interact with. Run it on your own server, keep full control of your content, and keep a personal space that still feels connected through optional comments and sharing. It stays lightweight, easy to deploy, and fully open-source.

Great fit if you want to:

  • run a personal public or semi-public timeline on your own domain
  • publish short posts, links, and media from one clean interface
  • keep data ownership while still getting RSS and optional comments
  • keep a personal space that supports lightweight social interaction without becoming a full social network

Probably not for you if you need:

  • a bi-directional knowledge base workflow (for example Obsidian-style PKM)
  • a team-first collaborative docs workspace (for example Notion-style docs)
  • a pure note-taking / memo tool with no timeline or publishing at all
