Bubble.io Tutorial: Build Your First App in 7 Steps (2026 Edition)
A complete step-by-step tutorial for absolute beginners. Build a working task management app with authentication, a personal database, and full CRUD operations — from account creation to a live deployed URL. Takes 3-4 hours.
A Complete Step-by-Step Tutorial for Absolute Beginners
This tutorial walks you through building a complete, functional web application in Bubble.io from scratch. By the end, you will have a working task management app with user authentication, a database of tasks, and the ability to create, view, and complete tasks. This tutorial assumes you have never used Bubble before. It takes approximately 3-4 hours to complete.
The Tutorial App
A simple task management app with: user sign-up and login, a personal task list unique to each logged-in user, the ability to create new tasks with a title and due date, mark tasks as complete, and delete tasks. Simple enough to understand every concept. Complete enough to demonstrate Bubble’s real capabilities.
Getting Started
Go to bubble.io and sign up for a free account. Click ‘New app’. Give your app a name (e.g. ‘my-task-app’). Choose the blank template (not a pre-built one — building from scratch teaches you more). Click ‘Create app’. You are now in Bubble’s editor. Take 5 minutes to explore the interface before starting to build: the left panel (elements), the centre canvas (your page), the right panel (element settings), and the top navigation (data, workflows, etc.).
Creating Your Data Types
Click ‘Data’ in the top navigation. You will see a ‘User’ data type already exists (Bubble creates this automatically). You need to add one more data type for tasks.
Data type name
: Task
// Add fields to the Task data type:
Field name: title
| Field type: text
Field name: due_date
| Field type: date
Field name: is_done
| Field type: yes/no (default: no)
Field name: created_by
| Field type: User
Next, click ‘Privacy’ next to the Task data type. Add a rule: condition ‘This Task’s created_by = Current User’. Check Find, View all fields, Edit, and Delete. This ensures each user only ever sees their own tasks.
Authentication
Bubble creates a default ‘index’ page (your home page) and a ‘login’ page automatically. Click on the ‘login’ page in the pages dropdown. You will see Bubble has already added a basic login form. Add a ‘Sign Up’ link below the login form that navigates to a signup page. Create a new page called ‘signup’ with a sign-up form element from Bubble’s element library.
On the index page, add a page load workflow: ‘When index page is loaded — Only when Current User is not logged in — Navigate to login page.’ This ensures only logged-in users can see the main app.
Displaying Tasks
On your index page, add a Repeating Group element. Set its type of content to ‘Task’. Set its data source to: ‘Search for Tasks — constraint: created_by = Current User — sorted by Created Date descending’. Inside the repeating group cell, add a text element displaying ‘Current cell’s Task’s title’ and a checkbox element for completion status.
Adding New Tasks
Add an input element (for the task title) and a date picker element (for the due date) above the repeating group. Add a ‘Create Task’ button.
Step 1
: Only when Input_title’s value is not empty
Step 2
: Create a new Task
title = Input_title’s value
due_date = DatePicker’s value
is_done = no
created_by = Current User
Step 3
: Reset inputs (clear the form)
Task Actions
Inside the repeating group cell, add a ‘Complete’ button and a ‘Delete’ button.
Step 1
: Make changes to Current cell’s Task
is_done = yes
// Delete button workflow
Step 1
: Delete Current cell’s Task
Add conditional formatting to completed tasks: when Current cell’s Task’s is_done = yes, apply a strikethrough style to the title text. This gives users visual confirmation that a task is done.
Launching Your First Bubble App
Click the ‘Preview’ button (top right) to run your app in the browser. Test the complete flow: create an account, log in, create a task, mark it complete, delete it. If everything works, your first Bubble app is complete.
To make it accessible via a public URL: click ‘Deploy to live’ in the top navigation. Your app is now live at yourappname.bubbleapps.io. To connect a custom domain, upgrade to the Growth plan and connect your domain in Settings.
Q: What if my repeating group shows no tasks?
Check two things: (1) Is the data source search constraint correct? (created_by = Current User). (2) Are the privacy rules set correctly? The Task privacy rule should allow ‘Find’ when created_by = Current User.
Q: How do I add more features?
This tutorial builds the foundation. Add features one at a time: task categories (add a category field and a filter option), due date reminders (add a scheduled backend workflow), and team sharing (add a shared_with list of Users field).
Q: Can I make this into a real SaaS product?
Yes. Add Stripe billing, a workspace model for multiple users, and more features. This tutorial’s Task data model is the starting point for dozens of real SaaS products.
