What Hammer does

Hammer is a tool for planning and writing stories: scenes, characters, notes and timelines, with apps for Windows, macOS, Linux and Android.

This server keeps the projects on all your devices in sync and belongs entirely to you. Accounts exist only for email addresses you have approved.

  • Sync between all your devices
  • Scenes, characters, notes, timelines
  • Invitation-only accounts
  • Runs on small resources

Good to know before the first start: The first visit sets up the admin account. Then approve your co-writers’ email addresses under “Allowed Users” in the admin area — and enter this server as the sync target in the Hammer app on every device.

Common questions

What does Hammer cost on Podless?
At the recommended size (1 cores · 2 GB RAM · 5 GB Storage) about €3.70 a month, billed by the hour. Stop Hammer and you only pay for storage.
Do I need technical knowledge?
No. No server, no Docker, no terminal commands. You click start and Hammer runs. Updates are tested on our own instances first and then rolled out.
Where does my data live?
In your own Hammer instance on servers in Germany and France; bulk storage sits in Frankfurt. Add your own S3 bucket and we back up there daily, encrypted.
Can I leave again?
Hammer is open source and keeps running on your own server. You fetch the files over a time-limited SFTP access and reach the database with the credentials from the dashboard.
