I Launched a SaaS in 6 Weeks Using Bubble: Real Steps

In just six weeks, a functional SaaS product was shipped using Bubble. Paying customers were charged even before a single line of code was written. This article covers the workflow, plugin choices, authentication setup, and database schema decisions that enabled quick demand validation and iterative improvements without needing to rebuild infrastructure.

Who this is for: Solo founders aiming to test a SaaS idea without hiring developers, wanting to earn real revenue before committing months to code, and okay with visual programming trade-offs for speed.

Week 1: Idea Validation and Core Schema Design

Everything started with a spreadsheet. It listed every user action the SaaS needed to support, mapping each to a Bubble data type. The product was a deadline-tracking tool for freelancers — users create projects, set milestones, and receive notifications.

Four data types were created in Bubble:

• User (built-in, extended with custom fields: subscription_tier, stripe_customer_id)
• Project (fields: name, owner [User type], deadline [date], status [option set])
• Milestone (fields: project [Project type], title, due_date, completed [yes/no])
• Notification (fields: user [User type], message, read [yes/no], created_date)

Bubble's database tab was used to model before touching the UI. Bubble's official documentation provides clear explanations on relational data structures. Parent-child relationships (Project → Milestone) were used to keep queries efficient.

Here's the thing: a common mistake here is overcomplicating privacy rules upfront. A single rule per data type was set: "Creator can view/edit." Granular permissions were added in the fourth week after real users exposed unforeseen edge cases.

Week 2: Authentication and Subscription Setup

The Stripe plugin (a free, official Bubble plugin) was installed and connected to a Stripe account. Bubble's built-in authentication handles signup/login, but subscription logic required workflow customization.

Three subscription tiers were created using Stripe's pricing table, then embedded in Bubble using an HTML element:

<stripe-pricing-table 
  pricing-table-id="prctbl_1234example"
  publishable-key="pk_test_your_key_here">
</stripe-pricing-table>

When a user completes payment, Stripe sends a webhook. Bubble's API Workflow (backend workflow) was used to:

1. Listen for checkout.session.completed event
2. Update the User's subscription_tier field
3. Store stripe_customer_id for future billing

Honestly, debugging this took two days. The webhook URL in Stripe's dashboard must match Bubble's backend workflow endpoint exactly: https://yourapp.bubbleapps.io/version-test/api/1.1/wf/stripe_webhook. Bubble's logs (accessible via the app's Logs tab) highlighted where JSON parsing failed.

Bubble's built-in payment workflows were skipped — they're easier for one-time charges but clunky for subscriptions. Direct Stripe integration allowed control over trial periods and proration.

Week 3-4: Core UI and Repeating Groups

Bubble's responsive engine changed in 2023 (according to Bubble's blog on the new responsive engine, now default for new apps). The new engine was used, which aligns elements using flexbox-like containers.

Four pages were built:

• Dashboard (repeating group showing user's projects, sorted by deadline)
• Project detail (nested repeating group for milestones)
• Settings (Stripe customer portal link, account details)
• Admin panel (conditional visibility if user role = admin)

Repeating groups are Bubble's list renderer. The data source for the dashboard's group was set to:

Do a search for Projects
  Constraint: Owner = Current User
  Sort by: Deadline (ascending)

Here's the thing: a performance issue arose, as load times exceeded 3 seconds with 50+ projects. Pagination (10 items per page) was switched to, and "Full list" mode was enabled only for CSV exports. Bubble charges for workload units — long searches on large datasets quickly consume capacity.

Reusable elements were used for the project card. This allowed design changes to be made once and updated everywhere. The card included:

• Project name (text element)
• Countdown timer (text element with dynamic expression: Project's Deadline - Current date/time)
• Status badge (shaped with border-radius, background color conditional on Project's status)

Week 4-5: Notifications and Backend Workflows

Bubble's scheduled workflows run server-side. A daily workflow (running at 6 AM UTC) was set up that:

1. Searches for projects with deadlines < 7 days away
2. Creates a Notification record for each
3. Sends an email via SendGrid API (using Bubble's API Connector plugin)

The API Connector setup was:

• Name: SendGrid Send Email
• Authentication: Private key in header (Authorization: Bearer YOUR_API_KEY)
• Body type: JSON
• Fields: to, subject, html_content

The call was initialized with sample data, later using dynamic data in the workflow. SendGrid's free tier allows 100 emails/day — enough for early validation. (SendGrid's pricing is public on their website; it wasn't cited because plans change quarterly.)

A "mark as read" workflow was also built, triggered by clicking a notification. This updates the Notification's read field, which filters the unread count badge on the nav bar.

Week 5-6: Testing, Launch, and Real User Feedback

Ten freelancers from a Slack community were invited to beta test. Bubble's privacy rules ensured users only saw their own data — essential before going live.

The live version was deployed (Bubble's "Deploy to Live" button) and a custom domain connected via Bubble's domain settings. DNS propagation took 45 minutes.

First revenue came 11 days after launch: one user upgraded to the $29/month tier. Stripe's webhook updated their account, unlocking unlimited projects (conditionals were used to hide the "Upgrade" button for paid users).

Three bugs emerged in the first week:

1. Timezone issue: Deadlines displayed in UTC, not the user's local time. A "timezone" field was added to User, using Bubble's :converted to timezone operator.
2. Email duplicates: The daily workflow ran twice if the server restarted mid-execution. A "last_notification_sent" date field was added and checked before creating notifications.
3. Mobile layout broke: The new responsive engine still requires manual breakpoints. A mobile version (320px width) was created and repeating group layouts adjusted.

No mobile app was developed. Bubble has native app wrappers (iOS/Android), but they add 300-500ms latency per page load. A responsive web app was used instead — 80% of users accessed it on desktop anyway.

What Nobody Tells You About Bubble for SaaS

Workload units are opaque. Bubble's pricing jumps from $29/month (Starter) to $119/month (Growth) based on workload consumption. A "search" costs units; a "create thing" costs units. You won't know your burn rate until you have real traffic. The app hit the Starter limit at 150 active users; it was upgraded to Growth.

Version control is weak. Bubble has a "Save point" feature, but no Git-style branching. The app was copied (manually) before major changes. This wastes time.

You can't self-host. Bubble is closed-source SaaS. If Bubble shuts down or changes pricing, you rebuild from scratch. For a six-week MVP, this risk is acceptable. For a product you plan to scale past $50K MRR, consider migrating to a custom stack once you've validated demand.

Plugins break. The Stripe plugin updated mid-development and deprecated a workflow action being used. Payment logic had to be rebuilt in 48 hours. Always check plugin changelogs before updates.

SEO is limited. Bubble's page titles and meta tags are editable, but you can't control render speed or server-side rendering in detail. Pages load in ~1.2 seconds (measured via Chrome DevTools), which is acceptable but not great. A content-heavy site wouldn't be ideal on Bubble.

Common Mistakes Made (So You Don't Have To)

Mistake 1: Skipping privacy rules until launch. The entire app was built with open privacy rules, then 8 hours in week five were spent locking everything down. Basic rules should be set in week one: "Creator can view" is sufficient to start.

Mistake 2: Not using option sets for status fields. Text fields were initially used for project status ("Active", "Completed"). Typos ("Activ", "active") broke filters. Option sets enforce consistency — define them in Bubble's Option Sets tab under Data.

Mistake 3: Overbuilding the admin panel. 12 hours were spent building charts and user analytics. No one used them. A CSV export should have been shipped, and then moved on.

Mistake 4: Ignoring Bubble's capacity limits. Repeating groups weren't paginated. At 60 projects, load times hit 4 seconds. Pagination is a one-click fix — it should be enabled from the start.

FAQ

Can I migrate off Bubble later without rewriting everything?

No. Bubble exports data (JSON or CSV), but not workflows or UI. If you migrate, you rebuild the app. Use Bubble to validate, then move to a custom stack (Rails, Django, Next.js) if you hit scaling limits or want more control.

Does Bubble work for mobile apps?

Bubble has iOS/Android wrappers, but they're web views with latency. For a native feel, use Bubble for the backend (API mode) and build the frontend in Flutter or React Native. This splits the work — not ideal for solo founders shipping fast.

How much does Bubble cost at scale?

Starter ($29/month) supports ~150 active users. Growth ($119/month) supports ~1,000. Above that, you're on custom pricing. The app hit Growth tier at 200 users. Scaling past 2,000 users brings Bubble's cost close to a custom Rails app's hosting + dev cost.

Can I use Bubble for enterprise SaaS?

Only if your customers don't audit your stack. Bubble's infrastructure is abstracted — you can't provide SOC 2 compliance details or host in a specific AWS region. For SMB SaaS, it's fine. For enterprise, you'll need to rebuild.

Bubble enabled shipping in six weeks by cutting scope hard: no mobile app, no analytics dashboard, no integrations beyond Stripe and email. Demand was validated with 10 paying customers, then iterations were based on real usage data — not hypothetical feature lists. For first-time SaaS builders, Bubble removes infrastructure decisions and focuses on the product. Once product-market fit is achieved, outgrowing it is likely — but by then, revenue will fund a proper rebuild.

Next step: Create a Bubble account, map the SaaS's core data types in a spreadsheet (users, entities, relationships), then build one page with one repeating group. Avoid touching workflows or plugins until data is rendered on screen. Complexity kills momentum — start with the simplest version that proves the idea works.
