About this app
A simple tool for building stories.
Multi-platform
This app is where ever you are. Your phone, tablet, desktop, laptop, this program can be installed and run, not simply a website-in-a-box, but instead using native client side technologies to provide the best experience possible.
Multi-Screen
Whether you are on a phone, tablet, or desktop, Hammer will make the best use of your screen space. Also supporting both light and dark modes.
Offline first
I was frustrated with most of the story writing software I was finding as they were using web technologies (aka: Web Page in a box) which always seems to run into problems while being used offline for long periods of time. Hammer is designed from the ground up to be entirely local, no internet connection required, ever.
Transparent Data
Your data is yours. It's not stored in the cloud, or some opaque database. It is stored in simple, human readable files, just using files and folders to define the project structure. You can open your OSes file browser and take a look for your self. If this program went away today you would be able to easily interact with your data.
Intelligent Syncing between devices
Your data can be synchronized between devices allowing you to work on your story from anywhere, and have no fear of a change on one device, overwriting a change on another device.
Optional and Self hosted Syncing
Syncing is entirely optional, you can install the client and use it on one device, or you can install the server and sync your data between devices. You could even use some other service to sync your data, like Dropbox, Google Drive or syncthing. (however these will only work for syncing between desktop computers. Mobile clients will have to use the built in syncing protocol.)
It's all up to you. Instructions can be found here: https://github.com/Wavesonics/hammer-editor/blob/develop/docs/HOW-TO-RUN-A-SERVER.md
If you don't know how, or just don't want to setup your own server, we're also running an official syncing server.
Official Server: hammer.ink
This is also the best way to support the project! Subscribe to our Patreon in order to get instant access to this official Sync server.
This official server endeavors to be a reliable, and secure way to sync your projects. We perform regular backups, and of course encrypt all of our data both in transit, and at rest in our database. Let us manage the server, and you worry about writing!

What's new
- Improvements
- Desktop window decoration migrated to the Nucleus TAO backend Server: trustProxyForwarding option reads real client IPs from X-Forwarded-* headers when running behind a reverse proxy, so the login rate limiter, login audit trail, and story reader counts reflect actual clients instead of the proxy Translations updated for German, Spanish, French, Italian, Portuguese (Brazil), and Ukrainian Rendered stories now use real book typography: indented lists, a centered scene-break ornament, tinted blockquotes, and deliberate blank-line spacing between paragraphs
- Fixes
- Client: text editor no longer drops block structure (horizontal rules, images, code fences) when a scene loads Client: font size changes no longer flatten list and blockquote indents Client: typed text after a size change could lose the paragraph's body style Client: F3 and Ctrl+Alt+S sync shortcuts work from anywhere in the project window Client: tag suggestion chips could add the typed prefix instead of the selected tag Sync: projects with a stale cached server id could get stuck failing "410 Gone" instead of recreating Web: strikethrough rendered as literal tildes instead of struck-through text
