The short version

  • Only Felt has a free tier, so it costs nothing to try first.
  • Each has a real cost: Felt felt publishes no prices for Professional or Enterprise, so buyers cannot compare against ArcGIS Online or QGIS with hosting without entering a sales process; Kepler.gl kepler.gl is a free open source library with no vendor-sold edition; confirmed by the absence of any App Store, marketplace or G-Cloud listing, support is limited to community GitHub issues rather than a purchased SLA.
  • They diverge on capability: Felt covers Real-time collaboration, Kepler.gl covers Core Functionality.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Felt

  • Felt publishes no prices for Professional or Enterprise, so buyers cannot compare against ArcGIS Online or QGIS with hosting without entering a sales process
  • Paid tiers are annual contract only with no monthly option, which excludes consultancies that need a tool for a single short engagement and forces them to the free non-commercial tier they are not licensed to use for client work
  • The API, JavaScript SDK and live warehouse connections are enterprise-only, so a mid-sized team that wants programmatic access has to buy the top tier rather than pay for one capability
  • Analytical depth is limited: there is no meaningful geoprocessing, topology checking or model building, so Felt sits beside a real GIS rather than replacing one
  • The Professional tier caps data processing at 25 GB a month and map views at 100,000 a month, which are easy to exceed with raster imagery or a public-facing map, and the overage terms are not published either

Kepler.gl

  • Kepler.gl is a free open source library with no vendor-sold edition; confirmed by the absence of any App Store, marketplace or G-Cloud listing, support is limited to community GitHub issues rather than a purchased SLA.
