A managed package in Salesforce is an upgradeable, namespaced bundle of components (objects, fields, Apex, Lightning Web Components, flows) that an ISV distributes for customers to install into their org. Its source is protected, it can be upgraded after install, and it is the only package type eligible for paid distribution on the AppExchange. Unmanaged packages, by contrast, are editable, not upgradeable, and meant for templates or one-off sharing.

Pro Tip

TL;DR: A managed package is a protected, upgradeable, namespaced bundle of Salesforce components used to distribute and sell apps on the AppExchange (Salesforce ISVforce Guide). Only managed packages can be listed as paid apps; unmanaged packages cannot be upgraded or licensed.

A managed package is how a Salesforce ISV ships a commercial app. It bundles all the app's components and locks them down: customers can install and use the package, but they cannot view or edit the underlying source. Every managed package carries a globally unique namespace prefix that keeps its components from colliding with anything in the customer's org (Salesforce Apex Developer Guide).

Three properties define it: it is upgradeable (you can ship new versions to installed customers), it is IP-protected (the source is hidden), and it is namespaced (no naming conflicts). Those three are exactly what commercial distribution requires.

The difference decides what you can do with the package. Only managed packages can be sold or upgraded.

Once an unmanaged package is installed, the creator has no further control over it, which is why it suits sharing a starting template rather than maintaining a product.

Pro Tip

Our finding: The single most useful thing to know is that "managed" equals "sellable and upgradeable." If you intend to list a paid app, the choice is made for you: it must be a managed package.

There are two ways to build a managed package. First-generation (1GP) ties the namespace to a single packaging org and is managed through Setup. Second-generation (2GP) is source-driven, uses Dev Hub and a namespace registry, and lets multiple packages share a namespace (Salesforce 2GP Guide). Salesforce recommends 2GP for all new managed packages.

Traditionally yes, because creating a managed package means writing Apex and Lightning Web Components and configuring 2GP packaging. That is changing. No-code generation platforms produce the components and assemble the managed package from a plain-language description, so you can have a managed package without writing code. See our guide on building a managed package without a Salesforce developer.

A managed package lets an ISV distribute and sell an app on the AppExchange while keeping the source protected and the package upgradeable (Salesforce ISVforce Guide). It is the standard vehicle for commercial Salesforce apps.

Managed packages are upgradeable, namespaced, and source-protected, and they are required for paid AppExchange listings. Unmanaged packages are editable and not upgradeable, suited to templates or one-off sharing. Only managed packages can be sold.

Yes. Upgradeability is a defining feature. An ISV can release new versions to installed customers, which is why managed packages are used for products that need ongoing maintenance, unlike unmanaged packages.

Traditionally yes, but no-code generation platforms like Appnigma now produce the Apex, components, and 2GP packaging from a description, so non-developers can create a managed package without writing code.
