Visual Sandbox vs Lumenfall

Both charge per run. One is an API. One is a place.

In short

  • Lumenfall charges the provider's public rate and adds nothing. No plan, no fee.
  • It is an API first. The Studio comes second, and the Playground needs a login.
  • We add a markup and give you a web app, a CLI, an MCP server and an API on one balance.
  • Both balances are prepaid and neither expires.

Our take. Use Lumenfall if you are a developer wiring models into your own product. Use Visual Sandbox if you want to make the thing.

Key takeaways

Is Visual Sandbox a good Lumenfall alternative?

Where we win

A place to make things
A web app with a library, shareable presets and every model page printing its price. Lumenfall is an endpoint.
Four doors, one balance
The web app, the CLI, the MCP server and the API spend the same cents.
Audio, 3D and vector too
Eleven Music at $0.19, Hunyuan 3D 3.1 at $0.63, Quiver Arrow at $0.25. Lumenfall lists image and video.
Skill packs for the agent
The MCP server hands an agent our prompting guidance before it prompts a model.
The balance does not expire
Neither does theirs. Both got this right.

Where Lumenfall wins

No markup
You pay what the provider charges. Their margin is a volume discount you never see.
One SDK for forty models
OpenAI-compatible. Send `size: 1024x1024` and it becomes whatever each model wants.
Automatic failover
When a provider goes down, the request routes around it.
A dollar to start
$1 of credit, no card, no minimum.
An Arena
Blind pairwise votes on model quality, with a public methodology.

Worth checking

Lumenfall is cheaper per run
By exactly our markup, on the models both carry. That is the honest headline.
It is for developers
Their founder says so on Reddit: 'our primary customers are developers, so the web UI is a bit technical.'
The Playground needs a login
lumenfall.ai/playground redirects to /app/playground. The price list is public; the try-it is not.
No team, no seat, no shared canvas
Listed as future premium features.
Image and video only
No audio, 3D or vector on the catalogue.

Two ways to pay per run

The price is on the page before the first run

This is the live price card off our Nano Banana 2 page. Lumenfall sells the same model at Google's public rate, through an API, and our price sits above it by our markup.

  • No account needed to read it, on either site.
  • Lumenfall's price is the provider's. Ours includes the web app, the CLI and the MCP server.
  • A quiet month costs $0 on both.

Lumenfall sells the call. We sell the place the call lands.

The money

Where the money goes

Both charge per run and neither bills a plan. The difference is what sits between you and the provider, and what you get for it.

  • Lumenfall's own page explains its money: volume discounts from providers, kept as margin, plus paid premium features later.
  • If you already have an OpenAI SDK client and your own front end, Lumenfall is the cheaper call. If you do not, the markup here buys the front end.
  • Their pricing page has a typo, 'GPR Image 1.5'. We mention it because a price list is only as good as its proofreading.
