Astella is an intelligent IDE for ActionScript, Flex, AIR and HTML5 development for web, desktop and mobile devices. It has a powerful source code editor, debugger, test runner, visual designer, profiler, version control integration and more.
Astella is essentially a subset of IntelliJ IDEA, with full support for listed languages and related technologies. At the same time, Astella includes only the relevant plugins, making it faster and easier to use for Flash, Flex and HTML coding. Additionally, Astella allows for simpler yet more powerful project configuration, so you can easily configure Flash projects of any kind or complexity.
You may switch to Astella if you develop in Flash or HTML only. You will need to stay with IDEA, if you also work on server-side Java code in the same project.
Exact date of Astella release is not yet defined.
Final pricing is not yet available, but Astella will surely be more affordable than IntelliJ IDEA.
