Build and train locally
Use the core Builder, your files, datasets, recipes, adapters, and standard exports without a shop entitlement.
Reallexi extension marketplace
Start free. Add only the workflow you need.
The open-source Builder remains useful on its own. Paid extensions add specialized automation, multimodal studios, managed delivery, updates, and entitlement-backed support.
The boundary, plainly stated
Open source is the platform. Extensions are optional accelerators.
Shop availability never disables community training, continuation, adapters, SafeTensors, local files, or existing Q8/F16 exports.
Automate specialized workflows
Buy an individual studio or managed operation when its time savings, guarded workflow, or support is valuable to you.
Operate the full capability set
Enterprise access includes paid capabilities under its written term, with organization-level activation and support.

How purchase and activation work
Four steps, with no hidden file upload or token handoff.
Choose one extension
Review its exact features, free boundary, license, cadence, and current live price.
Use hosted checkout
Stripe or PayPal collects payment details; Reallexi never receives raw card or PayPal credentials.
Verify your account
The signed provider webhook updates the server-authoritative entitlement. A success URL alone grants nothing.
Activate locally
The Builder checks the capability without uploading models, prompts, datasets, project paths, or provider tokens.
Secure hosted payment
Start checkout
Card details and PayPal credentials are collected only by the selected provider. Approved contributor or sponsor discounts are applied server-side after eligibility review.
