The short version

  • Only Buildkite has a free tier, so it costs nothing to try first.
  • Each has a real cost: Buildkite free plan caps at 5 users and 10 concurrent jobs, with 2,000 Linux vCPU minutes per month and 30 day build retention; 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.

Where each one falls short

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

Buildkite

  • Free plan caps at 5 users and 10 concurrent jobs, with 2,000 Linux vCPU minutes per month and 30 day build retention
  • Pro plan is $30 per active user per month, capped at 50 users, with only 10 of the up to 250 concurrent agents included before extra usage
  • Enterprise plan enforces a 30 user minimum even though pricing itself is custom
  • Hosted compute beyond included minutes is metered at $0.004 per vCPU minute on Linux and $0.02 per vCPU minute on Mac

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.
