FairStack vs Runway Verified pricing -- last updated 2026-10-31

Build on one balance: app, API and MCP, with music on the same key.

Runway App Studio (October 26, 2026) builds, runs and hosts apps on your Runway plan, and on Runway's Standard, Pro and Unlimited plans the monthly allowance expires on your billing date (Max and Team can roll up to one month over). The Runway API is billed separately from the Runway web app. FairStack has no plan and one balance for the web app, the REST API and the MCP server, billed at base model cost plus a flat 20% platform fee, shown before you spend.

If you are here, this is probably why

You are building a product or an internal tool and want one bill for the app and the API
A Runway monthly allowance that expires or rolls over at most a month doesn't fit how you work
Your product needs music on the same key as video
You want 62 video models to choose between, priced per second

The short version

Runway App Studio: building, running and hosting apps draw on your existing Runway plan. It is included in every paid Runway plan.
Runway plans: on Standard, Pro and Unlimited, "Monthly credits expire on your billing date." On Max and Team, up to one month of unused Runway plan credits may roll over (Runway help center). The Runway API is bought separately at $0.01 per Runway API credit, and Runway says web-app and API balances never mix.
Runway's API pricing lists no music models. FairStack serves music, voice and lip-sync on the same key as video.
FairStack: no plan, one balance across app, API and MCP. A 5-second shot on Kling 3.0 Standard: 5s x $0.12/s = $0.60.
