The short version

  • Only Sweep has a free tier, so it costs nothing to try first.
  • Each has a real cost: Finxact fiserv sells several core platforms, so a buyer should demand written investment and support commitments for Finxact specifically rather than trusting that the surviving brand implies a protected roadmap.; Sweep limited to JetBrains IDEs only, not available for VS Code or other editors
  • They diverge on capability: Finxact covers Cloud native core, Sweep covers Autocomplete.
  • 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.

Finxact

  • Fiserv sells several core platforms, so a buyer should demand written investment and support commitments for Finxact specifically rather than trusting that the surviving brand implies a protected roadmap.
  • Core migration is a multi year programme where the licence is a small share of total cost against integration, data migration and parallel running.
  • Buying the core from Fiserv strengthens a relationship that already covers cards and payments, which weakens your negotiating position across the whole estate at renewal.
  • It is a United States product with United States regulatory and product assumptions, so international banks get little from it.
  • Being part of a very large vendor changes the service experience: the responsiveness that made Finxact attractive as a startup is not guaranteed inside a company of Fiserv's scale.

Sweep

  • Limited to JetBrains IDEs only, not available for VS Code or other editors
  • Free tier limited to 1,000 autocompletes per month
  • API credit consumption varies by feature usage
  • Performance dependent on codebase size and indexing quality
