The operational costs of a viewer would be pretty minor.
In terms of development there are two things to consider: processing and interface. If the processing is serverside, there's already a lot of great options and I'd say IfcOpenShell is the best bet. If the processing is clientside, the options are ThatOpenCompany's platform but it doesn't scale and tends to fall flat on larger models, or IfcOpenShell-WASM which is super experimental and no idea how it scales.
For interface, there's tradeoffs with any you pick but none seem to outshine all the others: there's Xeokit, ThatOpenCompany, Cesium, or roll-your-own ThreeJS / BabylonJS. There's also VIM which I haven't investigated.
Easily top tier, lets yoy view, edit, convert ifcs.
Also lets you do stuff like clash detection, ids checking, naming validation, all for free and doesn't even require an account.
A very useful free viewer that can federate models, inspect and edit them. It also supports the insertion of GLB files (for terrains with orthophotos), and it can be customized if you have programming skills, as all the information and source code are available on GitHub. https://bim.santfeliu.cat/bimrocket/app.html

What about Speckle ?

Maybe not yet all features available but they develop fast.

Some might have an issue with this bit:
This is not a local tool.
