Starship UI puts an LCARS bridge in a tab.

What it is

An LCARS emulator that runs in a browser tab. Fourteen curated consoles plus a procedural generator that lays out fresh Okudagram panels, twenty-six working instruments including a master systems display and a warp core, four screen-accurate colour schemes, and the full set of alert conditions.

It is free, fan-made and non-commercial. Star Trek and LCARS are trademarks of CBS Studios and Paramount; this is a tribute, with no affiliation and nothing for sale.

Why a studio built a Star Trek toy

Because the procedural panel generator is a genuinely hard layout problem wearing a costume. LCARS panels look arbitrary and are not: the elbows, the sweeps and the block sizes follow rules, and a generated panel that breaks them reads as wrong immediately even to someone who couldn't tell you why.

Writing a generator that produces panels which look designed rather than randomised is the same class of problem as any constraint-driven layout, and it is a lot more fun to debug than an invoice template.

Everything in the browser

No install, no account, no server. The whole thing is static files and client-side JavaScript, which is why it loads fast and why it will still work in five years without anyone paying for a backend to sit there doing nothing.

It is also the least commercially useful thing we've built, and we're keeping it.
