How much do Sandboxer, Transformer and Flagger.gg cost?

How is Sandboxer priced?

Sandboxer bills each sandbox per second while it runs, and nothing while it's stopped. There is no free trial; plans start at $20 a month and are charged when you subscribe, and signing up and the docs need no card.

Plans are $20, $100, $500 and $2,000 a month, allowing 100, 300, 1,000 and 2,000 sandboxes at once. Each plan's price comes back as machine time, and extra time comes in $20 packs that never expire. Storage for stopped sandboxes and named snapshots is included, not billed. Details are on Sandboxer pricing.

How is Transformer priced?

Transformer's marketplace has no subscription, seats or minimums. A brand sets the payout on each offer, and sending offers is free. The brand's saved card is charged only when a creator accepts, and the payment is held until the Transformer team confirms the post. Creators keep 80% of the payout and of any sales commission, and Transformer keeps 20%: a $250 X post pays the creator $200. Each offer is prefilled with the creator's influencer value, an estimate from follower count on a published curve ($50 at 1k followers, $1,200 at 100k, $10,000 at 1M) adjusted for views and engagement, or with their own rate card if they've set one; the brand sets the final price. See Transformer pricing and fees.

How is Flagger.gg priced?

Flagger.gg is live as a hosted service. Anyone can sign up without a sales call, and each account gets its own organization and a project in auto-live mode. Flagger.gg doesn't publish pricing, so we don't quote a price here.

Do AI agents pay more than people?

No. All three are built so agents can use them directly, and none charges extra for agent access. Sandboxer's API, CLI, SDKs and MCP server use the same per-second rates. Transformer's API, MCP server and CLI are included in the 20% fee. Flagger.gg's MCP server, CLI and API come with the service. Read how to make a product AI agents can use.

How do you keep the costs predictable?

Use the limits each product enforces. On Sandboxer, give sandboxes short deadlines and keep auto-refill off, so new work stops at a zero balance. On Transformer, nothing is charged until a creator accepts. See how to stop an AI agent from overspending and how the three work together.
