CircleCI charges per credit with unpredictable bills. FastCI gives you fixed pricing, zero config, and built-in Ruby tools — all at a fraction of the cost.
CircleCI's credit-based pricing makes costs unpredictable. FastCI gives you everything you need at a fixed rate.
No more credit packs, overage charges, or surprise bills at the end of the month. One fixed price covers your entire team.
Ruby-optimized runners with pre-installed dependencies mean your builds start faster and run faster — no Docker layer caching tricks needed.
CircleCI requires complex .circleci/config.yml files with orbs and workflows. FastCI auto-detects your project and runs — zero YAML needed.
A typical 10-developer team on CircleCI spends $400-600/month on credits. With FastCI, that same team pays $149/month — fixed.
~$500/mo
Usage-based credits, per-seat charges, variable costs every month. Performance plan required for parallelism.
$149/mo
Fixed price. Unlimited builds. Built-in parallelism, code coverage, security scanning, and code quality — all included.
About 2 minutes. Connect your GitHub repo, and FastCI auto-detects your Ruby/Rails project. No config files to write or migrate — just push code and your tests run.
Yes. FastCI runs RSpec, Minitest, and Jest natively. Your existing tests work without modification. We also automatically split tests across parallel workers for faster results.
No. FastCI doesn't use config files — it auto-detects your Gemfile, database setup, and test framework. You can delete your .circleci directory entirely.
FastCI uses pre-built, Ruby-optimized environments with all common dependencies pre-installed. No Docker images to build or cache — your builds start immediately.
Absolutely. Many teams run both in parallel during a transition period. FastCI connects to your GitHub repo independently — there's no conflict with existing CI providers.
Stop paying per credit. Get fixed pricing, faster builds, and built-in Ruby tools — free to start.
