Simple creator pricing
Buy a one-time credit pack from $2.99 to create private thumbnails with commercial-use rights — no subscription.
Paid packs unlock private generation and commercial use while purchased credits remain active.
Generation cost follows resolution: 1K uses 10 credits, 2K uses 40, and 4K uses 60. New scenes and refinements use the same resolution-based rate.
New accounts do not receive free credits. The $2.99 Mini pack includes 10 credits for 1 generation at 1K. The $5 Starter pack includes 50 credits for 5 generations at 1K.
Paid credit packs are one-time purchases, never renew automatically, and expire 365 days after purchase.
Credits in plain English
Compare the approximate number of thumbnails included at each output resolution.
| Plan | Included credits | 1K · 10 credits | 2K · 40 credits | 4K · 60 credits |
|---|---|---|---|---|
| 10-credit pack | 10 | ≈ 1 generations | ≈ 0 generations | ≈ 0 generations |
| 50-credit pack | 50 | ≈ 5 generations | ≈ 1 generations | ≈ 0 generations |
| 1,600-credit pack | 1,600 | ≈ 160 generations | ≈ 40 generations | ≈ 26 generations |
| 6,000-credit pack | 6,000 | ≈ 600 generations | ≈ 150 generations | ≈ 100 generations |
Counts are calculated from each pack's credits and the current resolution costs; partial credits are rounded down.
Know how one-time billing, invoices, credit validity, and failed generations work before choosing a pack.
Payment details are handled by the configured payment provider, not stored by ThumbBlox.
Credit packs are one-time purchases and never renew automatically.
Provider-issued invoices appear in your Payments page.
If generation fails after credits are reserved, those credits are returned automatically.
Why creators upgrade
Paid credits give you room to test directions privately, keep the strongest composition, and use the result commercially.

Generate several directions from the same brief so you can compare ideas instead of settling for the first draft.

Use scene, theme, format, resolution, and reference controls to make each revision intentional.

Move from horror to simulator, survival, or tycoon concepts without rebuilding your workflow from scratch.
One focused workflow
Compare what you need to manage before a publish-ready concept reaches your screen.
| ThumbBlox | DIY production | Generic image tool | |
|---|---|---|---|
| Brief setup | Prompt plus Roblox-focused style controls | Coordinate tools, art direction, and exports | General prompt and manual formatting |
| First draft | Generated in the same guided workflow | Depends on artist and tool availability | Depends on prompt setup and revisions |
| Usage cost | 10 credits for one 1K generation | Software, assets, and creator time | Provider usage plus cleanup time |
| Output controls | 1K, 2K, or 4K in 16:9 or 1:1 | Set up and export manually | Varies by model and workflow |
| References | Attach reference images inside the workflow | Collect and share references separately | Support varies by provider |
| Iteration loop | Generate, refine, compare, and download in one app | Move files between tools and collaborators | Prompt, export, resize, and organize manually |
This compares the current product workflow, not guaranteed creative results. Generation time and output quality vary by brief, provider load, and selected resolution.
