Does Boromlia need installing?

No. It runs in any modern browser, so Windows, macOS, Linux, tablets and phones all work with nothing to download and no licence key to manage. The same account opens on every machine you use.

Can I publish a Boromlia timeline on the web?

Yes, on Advanced: as a public page that search engines can index and the site lists in its Examples; as a share link, read-only unless you allow more and kept out of search results; or as an embed on another website, one iframe tag that shows the live timeline.

Does Boromlia work offline?

No. It is a hosted web application and needs a connection. If working offline on your own machine matters most, Aeon Timeline is the better fit.

Aeon Timeline alternative: Boromlia vs Aeon Timeline

Choose Boromlia if

You work on Linux, a Chromebook or somebody else’s computer: Boromlia needs only a browser.
You want to publish: a public page, a read-only link or an embed on another site, on Advanced.
You want photos, places on a map and a source on each event more than a model of characters and arcs.
You want to start free, and have a one-time $49.99 option with nothing to renew.

Stay with Aeon Timeline if

You are plotting fiction and need characters, arcs, relationships and dependencies between events.
You need to work offline, with the files stored on your own machine.
You write in Scrivener and want Aeon’s integration with it.

The main difference: a desktop modelling tool versus a web record

Aeon Timeline models a world: who knows whom, and what depends on what. Boromlia records what happened and shows it: each event has a date and can carry a place, a source, people, tags and photos, drawn as a river, cards, a map or spans. There is nothing to install and no licence to move between devices, and on Advanced the people you give the share link to can add events to the same timeline, with no file to merge.
