Building 4 Shopify apps solo under Noomua. Shipping, failing, learning out loud.

[Stefan @noomuaa]

I spent months debugging Shopify app issues with no public answer. Billing API quirks. GDPR webhook gotchas. Cron patterns that don't blow up at scale.
I'd have paid real money for a newsletter that just told me the answers.
So I'm writing the one I need.

StockAlert v2 is live.

What shipped:

- Smart Mode: per-variant reorder predictions from sales velocity, lead time, and safety stock
- Multi-location inventory support
- Slack integration
- Email redesign with proper dispatch pipeline
- CSV import + bulk thresholds
- Full UI redesign

Smart Mode (Growth+ plans) replaces the "set one threshold for every variant" model every low-stock app uses. It computes when each variant will actually run out and tells you the best date to reorder.

Three months of work. Shipped today.

Portfolio check.
Viewly3D: 3 -> 12 installs
StockAlert: 5 -> 8 installs
Listify AI: Still at 4 installs
Viewly3D quadrupled. I expected StockAlert (Stocky shutdown angle) to lead. Instead the 3D/AR app - the one I almost shelved twice - is the one growing.
Building is the loudest signal. Predicting which app wins isn't.

Took a few days off X after my reach hit zero.Reach is still zero. But my head is clearer. Funny how much mental space the "check impressions" loop was eating.Back to shipping. The algorithm can do whatever it wants.

Three weeks ago I started posting here to build in public.
Went from a few hundred views per post to zero overnight. Tried everything - cooldowns, deleting posts, blocking bots. Nothing worked.
Turns out replying to the same 15 big accounts every day reads as bot behavior to the new algorithm. I was optimizing for old rules.
Reset: post less, link nothing, talk like a person. Solo dev building Shopify apps under Noomua. That's the account.

[Stefan @noomuaa]

Fresh small-account version of this. 3-week-old account, was hitting 100-300 impressions per post - past 2 days dropped to ~0, analytics broken too. No behavior change. If 34K accounts can't escape this, smaller accounts have zero path. Transparency would at least let people fix what's fixable.

Creating Shopify products takes 20 mins each. Listing 50? You're losing a weekend.

Listify AI v1.5 just shipped:
- Photo + name + Listify = listing in seconds
- Variants, categories, weights
- Bulk create 10 at once
- Push to Draft to review, or straight to Active

Built for stores shipping a lot of products - or new stores launching fast.

@gilgNYC Multi-agent UI feels like the "split pane" of 2026. Wonder how long until Shopify admin gets a "5 agents working on your store" panel.

[Stefan @noomuaa]

@shadcn The terminal would fit perfectly. Claude Code on a flip phone is the dev tool we deserve.

[Stefan @noomuaa]

@Shopify A/B testing variant A (ship the feature) vs variant B (perfect the listing) for Shopify apps. Variant A always wins. Then variant B sends a passive-aggressive email.

Launched my first paid Shopify App Store ad today.
$100 credit. 3 keywords. Bids at the floor.
Most of my target keywords had suggested CPCs of $13-45. Budget would have survived that, soo had to find different words.
Will report back what the $100 actually buys.

@ClaudeDevs Sleep was already a luxury. Now it's an option I can't afford.

[Stefan @noomuaa]

Day 28 with $0 and most sessions being my own - that’s the loneliest part. I’m in a similar spot: 4 Shopify apps live, MRR effectively zero, and half my 'users' are just me testing. The numbers don't move, and it makes you question everything. It’s not weakness; it’s just the part nobody posts about.

entrepreneur: “one final PDP tweak”

narrator: it was not final. there were, in fact, 23 more tweaks

[Stefan @noomuaa]

Going to be useful for my StockAlert app - currently logging every low-stock alert email in Postgres + tracking opens via Resend webhooks separately. One unified event log with idempotency keys built in solves both. Billable events is the interesting part - usage-based pricing on alert volume suddenly viable for solo devs.

@marclou Hyrox in 2 days while juggling 3 active projects is wild. The cross-training carries over more than people admit - the discipline of doing hard physical things makes a 12-hour debug session feel manageable. Good luck.

[Stefan @noomuaa]

Solo dev portfolio after 3 months on Shopify:

StockAlert - 5 installs
Listify AI - 4 installs
Viewly3D - 3 installs
StoreMD - still in review

Most people would call this a failure. I call it month 3 of a 60-month plan.

The apps that compound do nothing for the first year. Then one of them works.

@shadcn Building Shopify apps with Polaris. Every app I ship looks like every other Shopify app - and that's a feature, not a bug. Merchants don't want my UI to be special, they want it to behave exactly like the admin they already know. Familiarity > novelty for utility apps.

[Stefan @noomuaa]

@tobi Building 4 Shopify apps solo - the AI shopping shift is showing up in how I think about App Store SEO now. "Keywords ChatGPT would surface" is a different optimization target than "keywords merchants search." Whole new playbook forming.

[Stefan @noomuaa]

The Shopify revenue share rule changed on June 16, 2025.

Used to be: $1M exemption per year, reset every January.
Now: $1M exemption lifetime, since Jan 1 2025.

For a dev doing $1.5M ARR consistently:
- Year 1: pays 15% on $500k = $75k in fees
- Year 2+: pays 15% on full $1.5M = $225k

That's an extra $150k/yr in commission, every year, forever, once you burn through the lifetime cap.

Doesn't matter much under $1M lifetime. Once you cross it and keep growing, that 15% compounds into real money fast.

Wrote up this + a bunch more on what indie Shopify dev looks like in 2026:

[Stefan @noomuaa]

The 55% stat is the whole indie thesis in one number. The top 100 categories are crowded with venture-backed players and Shopify's own native features. Everything outside is where one solo dev can still build, ship, and own a niche end-to-end. More entrepreneurs follows naturally from making that path obvious.
