Regular TechCrunch readers might recall that, roughly two years ago (in June 2020), Salesforce made waves with the announcement of Code Builder, a web-based integrated development environment (IDE) modeled after GitHub Codespaces. Mum had been the word since then, but today, Salesforce unceremoniously dropped the beta for Code Builder, which the company describes in a blog post as having evolved into “a development environment optimized for Salesforce.”

As promised several summers ago, Code Builder — powered by Amazon Web Services — allows developers to launch an IDE in their browser from within their Salesforce organization. In addition to features like code completion, search, and refactoring, Code Builder ships with support for Salesforce frameworks and comes preinstalled with tooling including Salesforce Extensions.
