Deploy Memos in one click

Short Markdown notes on a private timeline

A self-hosted alternative to Google Keep.

Deploy on Pethost

What is Memos?

Memos is an open-source note-taking app for quick thoughts, the kind many people jot down in Google Keep. A memo can be one sentence or a longer entry in Markdown: you add #tags as you type, and it stays under the day you wrote it on a timeline. Search, nested tags, saved Views and a Calendar bring old memos back. Each memo is private until you share it with a link, make it public, or post it to a Space you share with others.

People self-host Memos to keep their notes on their own server, with no outside account. It is MIT-licensed and sends no usage data or analytics. A Telegram bot and a built-in MCP server let you add memos from a chat or an AI assistant. The catch is moving in: Memos imports only its own export, not notes from other apps.

Hosting Memos on Pethost

  1. You sign in to Pethost with a passkey, GitHub or Google. No machine yet? You pick a plan, and the link waits until it is ready.
  2. New project opens at Memos, and you click Create project.
  3. In a minute or two Memos is live at its own address with HTTPS. Its secrets are made at random, and its data is in the nightly backup.
  4. It is a project like any other: you or your agent can change it, roll it back or restore it.

Questions about Memos

Is Memos free and open source?

Yes. Memos is released under the MIT License, with no license fee, subscription or per-seat price. The only cost is the server it runs on.

Can Memos replace Google Keep?

For quick notes, yes. Memos has Markdown task lists, tags, and images, audio, video and documents attached to a memo, and its Web Clipper for Chrome and Firefox saves pages from the browser.

Does Memos have a mobile app?

Memos works on phones as a Progressive Web App: open your instance in the browser and add it to the home screen, where it opens in its own window.

How do I export my notes from Memos?

In Settings, Export & Import downloads every memo you wrote, with its attached files, as a ZIP of Markdown and JSON. Another Memos instance can import that ZIP into an account there.

Does Memos support multiple users?

Yes. Memos has two roles, Admin and User, and the first account created is the admin. Others register with a password, or sign in through an OAuth2 single sign-on provider a team already uses.

How much memory and disk does Memos need?

Memos is very light: tens of megabytes of memory, and years of notes take well under a gigabyte. On Pethost the Starter plan is enough for it, with room for other apps beside it.
