## Caveats

- Storage, snapshot GiB-month and public IPv4 prices are not published in the reviewed sources; null is not free.
- No guaranteed vCPU allocation published; browser-hour is not a verified 4-vCPU/8-GiB VM equivalent. The sizes card keeps unknown hardware null; do not coerce it to zero or auto-rank against resource-guaranteed VMs.
- Browser RAM is not published unless a specific mode overrides it.
- All products share a credit balance; do not count separate fetch, proxy and session allowances. 404/410 are billable successes.
- Top-up equivalent hourly rate in card is marginal only while packs are available. Engine cannot enforce four-pack cap, monthly rollover, request-specific response-size limits or per-plan network rates.
- Browser TTL at most 15 min: 8 h uninterrupted sessions infeasible. Requires checkpoint/auth restoration and at least 32 segments per eight-hour shift.
- GPU/guest OS/CPU/RAM, arbitrary snapshots, replay-storage fees and a separate CAPTCHA fee are unpublished.
- Browser Sessions also bill bandwidth at 25,000 credits/GB (= the credits of ~83 browser-hours per GB): about $14.77/GB at the Build B1 top-up value down to $2.78/GB at Scale S3. network.egress_gib stays null because the dollar value depends on the plan rung, so bandwidth-heavy workloads are underestimated.

## Gotchas

- All products share a credit balance; do not count separate fetch, proxy and session allowances. 404/410 are billable successes.

- Top-up equivalent hourly rate in card is marginal only while packs are available. Engine cannot enforce four-pack cap, monthly rollover, request-specific response-size limits or per-plan network rates.

- Browser TTL at most 15 min: 8 h uninterrupted sessions infeasible. Requires checkpoint/auth restoration and at least 32 segments per eight-hour shift.

- GPU/guest OS/CPU/RAM, arbitrary snapshots, replay-storage fees and a separate CAPTCHA fee are unpublished.

- Storage, snapshot GiB-month and public IPv4 prices are not published in the reviewed sources; null is not free.

- No guaranteed vCPU allocation published; browser-hour is not a verified 4-vCPU/8-GiB VM equivalent. The sizes card keeps unknown hardware null; do not coerce it to zero or auto-rank against resource-guaranteed VMs.

- Browser RAM is not published unless a specific mode overrides it.

## Worked example

Requested: 4 vCPU / 8 GiB; 50 concurrent × 8 hours/day × 22 days = **8,800 runtime hours**, 1,100 eight-hour starts if recreated daily; 30% CPU; 50 GiB-month snapshots; 100 GiB egress.

Time costs 8,800×300 = 2,640,000 credits. If 100 GB is billed browser traffic, add 2,500,000: total **5,140,000 credits**. Scale S1 plus one 845,000-credit top-up costs **$679** ($549+$130), meeting 50 concurrency. Growth G3 plus the maximum four 525,000-credit top-ups reaches only 5,100,000, so it cannot cover this workload. Browser sessions must be split to no more than 15 minutes; no guaranteed 4/8 hardware or general snapshot tariff.
