Browser app building
Base44 online gives you a browser-first way to describe an app, shape its screens, and review the result without beginning with a local development environment.
At a glance
The online experience is most useful when you want to move from an app idea to a visible, testable direction before committing to a heavier technical setup.

Who it suits
Different audiences can use the same browser surface for different jobs, from validating an idea to clarifying a project brief for a technical team.
You have a service idea but need to see its core screens before explaining it to a partner or developer.
A visible first direction makes the conversation more concrete and exposes missing decisions earlier.
Turn an app idea into a first directionYour team repeats a workflow across spreadsheets, messages, or forms and needs a clearer internal tool concept.
You can describe the process in everyday language and identify the screens, roles, and actions that matter.
Map a workflow in the browserYou want to explore structure and interaction ideas without opening a full local project for every variation.
Browser-based iteration helps compare directions while the brief is still changing.
Explore interface directions onlineA client or stakeholder needs a shared starting point before implementation details are finalized.
A concrete app concept gives the team a stronger basis for estimating, refining, and prioritizing work.
Create a shared project starting pointHow it feels
The strongest value appears in the handoff between intention and structure: you start with what the app should do, then refine what users need to see and use.
01 · Define
1
Describe the user, the task, and the result you want rather than trying to name every technical detail. A focused brief gives the workspace a useful direction and keeps the first pass tied to a real need.
02 · Structure
2
Once the central workflow is visible, look for gaps in navigation, permissions, forms, and feedback. This is where an abstract idea becomes something you can discuss, test, and improve.
03 · Refine
3
Useful iteration is specific. Instead of asking for everything at once, point to one change at a time: simplify a form, add a status view, clarify a role, or make the mobile flow easier to follow.
Before you begin
An online builder can accelerate the first mile, but it does not remove the need for clear requirements, review, or decisions about what the finished product must support.
A browser with a stable internet connection
RequiredThe workspace is accessed online.
A clear description of the user and main workflow
RequiredSpecific goals produce more useful first passes.
The pages, roles, or actions your app needs
RequiredList the essentials before adding secondary features.
Time to review and refine the generated direction
RequiredThe first result should be treated as a starting point.
A complete technical specification before the first prompt
OptionalYou can clarify details as the concept develops.
Local development tools installed in advance
OptionalThey are not needed to begin exploring the browser workflow.
The workflow
These practical markers describe the shape of the online experience without pretending that every project follows the same timeline.
Choose a starting lens
The online workspace can support several kinds of early thinking. Pick the lens that matches the decision you need to make first.
Start with the audience, the problem, and the one action that matters most. The goal is not to specify everything; it is to make the central experience visible enough to question.
Describe the steps, handoffs, and outcomes in the current process. This helps expose where a future app needs statuses, forms, permissions, or notifications.
Use the browser experience to create a shared reference point for product, design, and engineering discussions. A visible direction makes tradeoffs easier to identify.
Simple sequence
A useful first pass comes from moving through the process deliberately rather than trying to solve the entire product in one request.
State who the app is for, what problem it addresses, and the primary action users should complete.
Inspect the proposed screens, navigation, content, and workflow. Look for missing steps or unnecessary complexity.
Ask for a focused change, such as a clearer form, a new role, a status view, or a better mobile path.
Use the result to continue exploration, align with collaborators, or define the requirements for deeper implementation.
Start in the browser
Describe a real workflow and use the online experience to turn an abstract request into something you can review. Keep the first brief focused, then refine the part that matters most.
Try Base44 onlineCommon questions
The browser-first workflow is designed to let you begin without setting up a local development environment. You still need a compatible browser and an internet connection to access the online workspace.
The online experience may let you begin exploring an app idea without a local setup, but availability and included usage can depend on the current offering. Check the live workspace for the terms that apply when you start.
You can describe an app idea, its intended users, key screens, and the workflow those users should complete. Clear details about roles, actions, and outcomes usually make the first direction more useful.
It can be useful for shaping product concepts, workflows, and early prototypes, but a production release still requires review of security, data, permissions, testing, and operational needs. Treat the first online result as a foundation for those decisions, not as a substitute for them.
