Sascha Thiele for Lovable
Application · Design Engineer

I changed one thing in Lovable.

I rebuilt Lovable's home screen and changed one component, the one I think has the biggest effect on revenue. Try it, then flip back to the original.

Who
Sascha Thiele, freelance design engineer. 6 years of UX/UI for Mercedes-Benz, Amazon, Ottobock and Deutsche Bahn, and 2 iOS apps of my own on the App Store.
Role
Design Engineer. Based in Leipzig, open to remote or relocating to Stockholm. Available now.
The change
Lovable's static "Upgrade to Pro" card becomes a live credit meter that offers the upgrade when intent peaks.

Independent concept by Sascha Thiele. Not affiliated with or endorsed by Lovable.

Credits you can see.

Send a few prompts and watch the sidebar. Each message costs one of the 5 free daily credits.

Best on a larger screen. On a phone, tap the cards below the prototype to see each state.

Got an idea, Sascha?

Out of credits for today. Your prompt is saved, nothing is lost.
≈ 1 credit Build
Import a project Import a website

Type into the prompt and press Enter, or use "Send a prompt for me". Or click a card below to jump straight to that state.

01
The balance is always visible

"Upgrade to Pro" becomes a live meter. It counts in edits, not abstract credits, and always shows when credits reset.

02
Cost before you send

A small "≈ 1 credit" label next to Build. You see the cost before you spend, so the bill never surprises you.

03
Upsell when intent peaks

With one credit left, mid-build, the meter turns into an offer. It's sized to your own pace, not "unlock more features".

04
No dead end at zero

No blocking wall. The prompt is kept, the path forward sits inline, and "remind me" brings you back when credits reset.

Show in prototype ↑
Original: the corner card says "Upgrade to Pro · Unlock more features" all day. It never changes and never says what you'd unlock. Credits drain without a trace until the wall. Send 5 prompts to see it.
Why this, of everything

Credits are Lovable's currency. The home screen hides them.

I went through seven screens: home, ⌘K, connectors, plans, referrals, growth and bonuses. Four things stood out.

01 · Home

The only upsell on screen says nothing.

Upgrade to Pro · Unlock more features sits in the corner all day, the same for every user at every moment. When a nudge never changes, people learn to stop seeing it.

02 · Home

You first learn your balance at zero.

Credits drive the business, but the home screen never shows them. The first time you meet them is at the wall, mid-idea. That is the worst moment to show a paywall, and it's the only time one appears.

03 · Plans

Expansion revenue hides in a dropdown.

Pro and Business both default to 100 monthly credits. Users who have never seen their own burn rate can't tell which tier fits, so they pick the smallest one.

04 · Modals

Bonuses, referrals and growth all compete for attention.

Three different modals are about getting more out of Lovable. All of them are worth more when people can see the thing they earn: credits.

The one change

Turn the static "Upgrade to Pro" card into a live credit meter. Show the balance, show the cost before sending, and offer the upgrade when intent peaks, at a tier that fits the user's pace.

What it could be worth

Plug in your real numbers.

The defaults are estimates built from public figures (source below), plus two assumptions of my own, which are marked. You know the real numbers. Move the sliders and the result updates.

Estimate: 8M users (late 2025) minus the ~7.8% who pay (180k of 2.3M, July 2025).
Estimate: ARR grew from $100M to $500M in ~11 months. At $46 per user that's ~66k net new payers a month, out of ~7.4M free users.
My assumption. Contextual, usage-based upgrade prompts typically convert better than static ones. This is the hypothesis to test.
Estimate: $100M ARR ÷ 180k paying subscribers (July 2025).
My assumption.
Order-of-magnitude estimate
+0%
more ARR after 12 months, relative to $500M (June 2026)
Extra paying users / month0 Extra MRR per monthly cohort$0 Extra paying users after 12 mo.0 Added ARR after 12 months$0

Illustrative only. It's simple cohort math with linear retention decay and no reactivation or seasonality, in USD. The real number comes from the A/B test below.

Source for users, subscribers and ARR: DemandSage, Lovable Statistics (2026), which compiles TechCrunch, Sacra and Dealroom. Lift and retention are my assumptions.

How I'd ship it

Small to build. Easy to measure.

Experiment

50/50 on new free signups

  • One component swap, behind a feature flag
  • Two weeks or until significant
  • Primary metric: free → paid within 14 days
Secondary

Watch the money and the mood

  • Share of upgrades above 100 credits
  • D7 return rate of users who hit zero
  • Credit-related support tickets
Main risk

Visible meters can make people stingy

  • Guardrail: messages sent per active user
  • Speaking in "edits" and showing the reset timer reduce anxiety
  • If usage drops, test hiding the meter above 50%
About me

Design meets engineering.

I'm Sascha, a freelance design engineer in Leipzig. I spent six years designing products for Mercedes-Benz, Amazon, Ottobock and Deutsche Bahn. Each role moved me closer to implementation. Since 2024 I've built the things I design myself, including two iOS apps that are live on the App Store.

I just finished a full-time AI engineering programme, so when I design for AI products I know how they work underneath.

Why Lovable

Giving people tools that let them create things they could never have built before is one of the most powerful things software can do. That's what Lovable does, and I want to help build it.

I'm your target customer

As a design engineer I sit exactly where Lovable aims: I think in interfaces, I can read the code, and I want to get from idea to working product without waiting on anyone. I'd be designing the product I'd want to use myself.

I design for the business

This application is built around a revenue hypothesis, not a mood board. That's also how I worked with enterprise clients: every screen had to earn its place.

I build what I design

This page is one hand-written HTML file. My products are shipped code, not Paper files. Engineers get decisions they can build from, and I can build them too.

Next step

Let's build the next one together.

I'd love to talk about this change, the ones I left out, and what I could build at Lovable.
