Salesforce developer org vs sandbox org - Explain the difference?
I've been doing some trailhead and there was a paragraph:
"Meet Sally, Gunjan, and Ali. These three amazing developers are working on an exciting new Salesforce app, and tomorrow is the big launch day. Sally and Gunjan have been working in developer orgs, and Ali in a sandbox org. Sally creates an unmanaged package and pushes it to the sandbox org. Gunjan does the same. What could go wrong?"
This got me confused, because there are these types of sandboxes:
Developer Sandbox
Developer Pro Sandbox
Partial Copy Sandbox
Full Sandbox
What's the difference between developer org and sandbox org?
A sandbox org (developer, dev pro, partial copy, full copy) are attached to a (paid) Production org. Sandboxes can be refreshed so that they contain all of the same metadata (SObjects, custom fields, remote site settings, apex classes, etc...) of another org (typically the production org). A Salesforce developer org (a.k.a. the Developer Edition of SFDC) is different from a developer sandbox org. Developer orgs are free, and have some pretty strict limitations put on them (to prevent businesses from running off of the free version) like a piddly 5MB of storage space and not being able to create sandboxes.
