Marketplace and add-ons
Install extensions into your apps — from single components to complete bundles.
The marketplace offers add-ons that extend your applications: components, template packs, and container-based services that run alongside your app. Products install as single items or as bundles whose components install in a defined order.
Installing
Pick a product, review what it includes and what it costs, and install into a chosen app. Bundles show each included component and whether it's required or optional.
Container-based add-ons
Some add-ons run as isolated services with their own compute. These are held to a strict disclosure standard: every access they make to your tenant data is written to a tamper-evident ledger your customers can verify. What an add-on runs is frozen and fingerprinted at the moment it's invoked, so the audit trail reflects exactly the code that touched the data.
Add-ons never get blanket access to your data. Their network reach is sealed or allow-listed, and their data access is logged in a ledger that cannot be silently edited after the fact.
For the full model — declared endpoints, egress policies, immutable versions, and fingerprints — see Appliances and their endpoints. And if you've built something worth selling yourself, the Selling Templates section covers the other side of the counter.
