Two machines, one seam, no winner

4comparisons published

Side-by-side comparisons of two providers for a specific use case. Same fields for both, official sources, and a verdict phrased "choose A if, choose B if". Never a winner declaration.

E2B's free Hobby plan is $0 per month plus per-second usage, with a one-time $100 usage credit and no credit card required. Daytona includes $200 in free compute at signup, also with no card, but its billing docs bar the free credit from GPU sandboxes. Both bill per second; the grant size and what the credit is allowed to buy are the real differences.

Railway's trial gives you $5 in credits for 30 days with no credit card required, then lands you on a Free plan with $1 of monthly usage credits. Render's Free instances cost $0 with 512 MB RAM, 0.1 CPU, and 750 free instance hours per workspace per month, spinning down after 15 minutes without traffic. One free path is a front-loaded trial that leaves a tiny permanent floor; the other is a recurring monthly allowance with cold starts.

Contabo offers Core VPS plans from EUR 4.40/month for 4 vCPU / 8 GB RAM / 100 GB SSD, billed monthly with no signup credit. DigitalOcean Basic Droplets start at $4/month for 1 vCPU / 512 MiB / 10 GB SSD, billed per second with a 60-second minimum and monthly cap, plus a $5 signup credit for 90 days. The extra CPU cores on Contabo look compelling on paper; the question is whether the fine print matches the headline.

RunPod gives you GPU pods and serverless endpoints billed per second with no data-transfer fees. Modal gives you a serverless platform with per-second GPU rates, no minimum usage-time increments, and $30/month included compute on Starter. Both bill per second; the difference is whether you want a persistent box or a scale-to-zero function platform.
