Is the browser studio open to everyone?
The pages are open in any tab. Working in the studio, including saving projects and rendering, takes an account with an active plan, which is set out on the pricing page.
What is the closest alternative to Resolve on a locked-down laptop?
A browser editor is the category that fits, because it asks for no install rights at all. Among browser editors, compare the depth of the colour, audio and delivery stack rather than the look of the landing page.
Should I switch tools if my project is simple?
Tool switching has a cost: projects, renders and muscle memory do not travel cleanly between vendors. Single-clip social work is fine on a phone editor; anything with structure is better served by staying in one pipeline.
Can I bring projects in from another editor?
Edits come across as exports, XML or rendered media rather than as native timelines. The practical route is to bring the finished media in and rebuild the timeline once, then keep future work in one place.
