Let your coding agent work through the night.
Claude Code, Codex and the rest run on a whole Linux machine of their own, with root, Docker and your repository. In the morning there is a pull request, and the machine is still there.
A week of one agent.
It runs when there is work and stops when there is not. The machine and its disk stay the same all week, so nothing is set up twice.
Look over its shoulder.
An agent working alone for hours is only useful if you can see what it did, and step in when it is stuck.

The bill for one run.
Billed by the second at list price. Nothing for the hours it waited, except its disk.
Five agents doing this every working day come to about $27.50 a month on the free plan: no fee, paid from top-ups as they run.
What it costs elsewhere.
One month of the same work, at each provider's own list prices, plan fees included. Read on 25 October 2026.
| provider | how it is priced, for this | a month |
|---|---|---|
| agental | Free, no fee; $27.50 of top-ups that add $27.50; 880 h at $0.027, 2,770 h stopped at $0.00135 | $27.50 |
| Fly Sprites | Billed on use: at their own example's load (30% of 2 CPUs, 1.5 GB), $0.0575 an hour; 40 GB kept cold | $54.54 |
| Vercel Sandbox | Pro, $20 credit; $0.128 per busy vCPU-hour at 30% busy, $0.0212 per GB-hour; 24 h runs at most | $142.21 |
| Daytona | No plan; $0.1656 an hour, and its largest disk, 10 GB, past the free 5 GiB at $0.000108 per GiB-hour while stopped | $147.22 |
| Modal | Starter, $30 credit; $0.1419 per core (2 vCPU) and $0.024 per GiB, an hour | $179.35 |
| E2B | Pro, $150 a month, needed for runs over an hour; $0.1656 an hour | $295.73 |
Sprites and Vercel bill CPU only while it is busy, so their figure moves with the load; ours is the machine's whole hour, busy or not. Daytona's $200 and E2B Hobby's $100 are credits once, not each month, and are left out. Daytona's disk tops out at 10 GB, a quarter of ours.
The same, elsewhere.
