Budget

Create a table estimating your costs, eg cloud.
If you get free compute, include this in a separate column.

Analysis

GitHub Pro

A GitHub Pro plan is required in order to have a wiki on a private repository. However, GitHub Pro is included in the GitHub Student Developer Pack, which is free for students.

See more GitHub plans information here.

Mapbox API

This project's use of the Mapbox GL JS library introduces costs associated with "Map loads". As per the Mapbox pricing page:

A map load is counted every time Mapbox GL JS initializes on a webpage or in a web app. A map load includes unlimited Vector Tiles API and Raster Tiles API requests.

Within the first week of development, frontend team members have incurred roughly 100 map loads each. If this first week of development is representative of what's to come, then we expect roughly 400 map loads per month. With this, we remain far below the 50k free map loads per month that Mapbox offers (especially since each developer uses their own API key).

Map loads incurred by end-users is another question, but there isn't yet enough information to make useful predictions on this cost yet.
