5.1Bubble: complete web app
The essentials in 30 seconds
- Three pillars: pages (interface), database (types + fields), workflows «when… then…» — think in that order.
- Bubble = custom-built: user accounts, rich business logic, complex interactions — where Glide/Softr reach their limits.
- Power = learning curve: this is «visual development» — start simple, iterate in preview, validate fast (MVP).
Running case — Lina and file tracking in Oran
Lina, a digitalisation officer in Oran, tracks partner files across scattered spreadsheets: duplicates, conflicting versions, forgotten follow-ups. Her need goes beyond a simple shared base: accounts per department, validation rules, a dashboard. She chooses Bubble to lay down an MVP: data types, one page, one creation workflow. This section tells the story of her foundation — and the thread continues in 5.2, 5.3, 5.4 and 5.5.
This same case returns in the lesson, the diagram, the script and the 48h challenge — and continues in 5.2, 5.3, 5.4 and 5.5.
1. A real platform, not an improved spreadsheet
Bubble is the most powerful no-code tool for building a complete web application: user accounts, database, business logic and a custom interface. You visually design the pages (drag-and-drop elements), the database (data types and fields), and above all the workflows («when the user clicks here, then do that») that carry all the behaviour. Lina rediscovers the concepts of real software there — data, states, conditions — without writing code.
The ordering rule: data → interface → workflows. An application designed backwards (screens first, data afterwards) gets rebuilt twice. So Lina starts with her types (Partner, File) and their fields before drawing a single page.
2. MVP and visual development
Bubble can build MVPs (minimum viable products) and real internal platforms: a management tool, a mini tracking platform, a community space. Its power has a counterpart: a steeper learning curve than Glide or Softr — it is almost «visual development». Lina accepts learning in small steps: one page, one form, one workflow, then she enriches it.
For an ambitious project that goes beyond a simple base or automation, Bubble is the culmination of the no-code journey. But the economy rule: start with the simplest thing that meets the need — only bring out Bubble when complexity genuinely demands it (see 5.2).
3. When to choose Bubble (and when not to)
Choose Glide or Softr (5.2) if the need is to turn an existing base into a clean app quickly, with moderate logic. Choose Bubble if you are aiming for a genuinely custom application: rich business logic, complex interactions, advanced accounts and rules. Lina decides: her multi-department validation circuit requires conditional workflows — that means Bubble.
The limits to know: very heavy loads, extreme performance or deep technical customisation sometimes belong to code. To test, launch and run a real product and iterate fast, Bubble is more than enough.
🔎 Concrete example — Lina's MVP in Oran
Data, interface, logic — the foundation.
Data types: Partner (name, department, contact) + File (title, status, linked partner).
«Follow-up» page: input field + «Create» button + repeating list of Files.
Workflow: when «Create» is clicked → save a File (status = «New»).
→ preview: Lina creates a test account, adds a file, checks the display.Reading: each pillar is visible and testable separately.
Lesson: start simple, iterate on the logic — the MVP proves, then you enrich.
Section vocabulary
- Bubble
- No-code platform for building complete web applications (interface, base, logic) without coding.
Simple example: Lina builds her file tracking there with accounts and rules.
What it is not: a simple screen generator from a spreadsheet.
Reflex: does my need go beyond a base + generated screens?
- MVP
- A minimal but working version to test an idea quickly with real users.
Simple example: Lina launches a one-workflow tracker before adding validations.
What it is not: the perfect final application on the first attempt.
Reflex: what is the smallest scope that proves usage?
- Workflow (Bubble)
- «When… then…» logic triggered by a user event.
Simple example: When Create is clicked, save a File with the New status.
What it is not: simply drawing a button on a page.
Reflex: does each button do something tested?
- Database (Bubble)
- Data types and fields that structure the app's information.
Simple example: Lina's linked Partner and File types.
What it is not: screens drawn with no data model.
Reflex: data first, screens next — always.
- Element / page
- Visual components (buttons, fields, lists) assembled on pages.
Simple example: The repeating list displays the files created by Lina.
What it is not: the business logic itself.
Reflex: does the interface faithfully reflect the base?
In practice — Laying the foundations of a Bubble app
- Create a Bubble application and define its data types (e.g. User, Project) and their fields.
- Build a page by dragging elements (input field, button, repeating list to display data).
- Add a workflow: «when the user clicks Create → save a new Project in the base».
- Test the app in preview mode (create an account, add a record) and iterate on the logic.
Ready-to-say script — scoping your Bubble MVP
«For our tracking in Oran, I suggest a Bubble MVP: two data types (Partner, File), one tracking page and a single creation workflow. We test in preview with two departments, then add the validation rules. Goal: prove usage before enriching. »
Say in a scoping meeting to align the team on the minimal scope before any screen.
Copy-paste template — Bubble MVP scoping
BUBBLE MVP — SCOPING
NEED: _______________
DATA TYPES: 1) ___ (fields: ___) 2) ___ (fields: ___)
PAGE: ___ (elements: input + button + list)
WORKFLOW 1: when ___ → then ___
PREVIEW TEST: test account + 1 record created: YES / NO
NEXT (only after test): _______________Solo / small budget
Lina alone: a single type + one page + one workflow, tested in preview before any enrichment — the MVP fits in one evening.
Small business / small team
Scope narrowed to a single process (file tracking), one reviewer validating each iteration.
SME in Oran
Lina schedules tests with two pilot departments in Oran, in French, before extending accounts to the other teams.
Team getting started
Pair: one models the data, the other lays out the page; peer review of the workflow before each preview.
✓ Best practices
- Start with the simplest thing that meets the need.
- Think data → interface → workflows (the three pillars).
- Iterate fast in preview mode to validate an idea (MVP).
✗ Common pitfalls
- Bringing out Bubble when Glide/Softr would be enough.
- Underestimating the learning curve.
- Targeting very heavy loads / extreme performance (no-code limits).
Key takeaways
- Bubble creates complete web applications: accounts, database, logic, custom interface.
- Three pillars: pages (interface), database, workflows («when… then…»).
- Ideal for MVPs and real internal platforms (management tool, tracking, advanced member space).
- Power = steeper learning curve: this is «visual development».
48h challenge — apply tomorrow
Define your 2 data types and your workflow #1 on paper (template above): could you explain them to Lina in 2 minutes?
- I can name the three pillars in order (data, interface, workflows).
- My MVP scoping (2 types + 1 workflow) is written down.
- I know when to prefer Glide/Softr over Bubble.
Frequently asked questions
Bubble or a simpler app builder (Glide, Softr): how to choose?
A question of power vs simplicity. Choose Glide or Softr if your need is to turn a base (Airtable/Sheets) into a clean app quickly, with moderate logic (section 5.2). Choose Bubble if you are targeting a genuinely custom application with rich business logic and advanced rules: that is where Glide/Softr show their limits. Rule: start with the simplest thing that meets the need, and only bring out Bubble when complexity genuinely demands it.
Can you really launch a business on a Bubble app?
Yes, many startups launched their product on Bubble, especially at the MVP stage and beyond for management applications and light platforms: validating an idea and getting real users without a development team. Limits appear with very heavy loads or deep technical customisation — that is where people sometimes migrate to code. But to test, launch and iterate fast, Bubble is more than enough.
