CI cost showdown: same 20K minutes — GitHub $120 vs Blacksmith $80 vs Celesto $13

CI is the bottleneck for fast-shipping teams. For 20,000 CI minutes/month on a 2 vCPU / 8 GB runner: GitHub Actions costs $120, Blacksmith $80, and Celesto CI just $13.33 — nearly an order of magnitude apart.
The attached screenshot cites Lindy founder Flo Crivello: his team's CI bill grew from $230 to $4,300/month, yet he calls it the cheapest money spent on making agents faster; David Ondrej adds that GitHub Actions spend is spiraling. The thread reflects how agent-era CI usage is exploding — and the opening for cheaper runners.
