When Next.js Is the Wrong Choice: The Lim­its Hon­est Ad­vi­sors Name

Next.js is ex­cel­lent — and for a whole class of projects it's the wrong call. An hon­est bound­ary for de­ci­sion-mak­ers: ov­erengi­neer­ing, mi­gra­tion costs, and the point where I'd pick it any­way.

Core Web Vi­tals Are Rev­enue: What CIOs Ac­tu­al­ly Need to Know About Per­for­mance

Per­for­mance is not fron­tend cos­met­ics. It is a busi­ness met­ric. Treat Core Web Vi­tals as a tech­ni­cal de­tail and you leave both rank­ing and rev­enue on the ta­ble. Why Next.js gives you the best start­ing con­di­tions, and why that alone guar­an­tees noth­ing.

Next.js as an in­te­gra­tion lay­er for lega­cy sys­tems: mod­ernise with­out the big bang

SAP, TYPO3, Sales­force and age­ing ERP sys­tems aren't go­ing any­where. They still have to talk to mod­ern fron­tends. How Next.js works as an in­te­gra­tion lay­er and Back­end for Fron­tend to de­cou­ple lega­cy step by step, what holds the pat­tern up, and where it tips over.

Next.js on Het­zn­er in­stead of Ver­cel: the sov­er­eign al­ter­na­tive

Ver­cel is con­ve­nient and sits un­der US law. Next.js is open source and runs self-host­ed on Het­zn­er with Coo­lify and Dock­er, sta­bly, from around 39 eu­ros a month. Why data sov­er­eign­ty is­n't op­tion­al for se­ri­ous or­gan­i­sa­tions but a re­quire­ment, and what the switch hon­est­ly costs.

Next.js + Medusa over SAP Com­merce: why I pick the open-source stack

SAP Com­merce + An­gu­lar gets sold as the safe en­ter­prise stan­dard, usu­al­ly with­out the full bill at­tached. Here is why Next.js + Medusa wins strate­gi­cal­ly on TCO, ven­dor lock-in and de­vel­op­er avail­abil­i­ty, and where SAP still re­mains the right call.

Mi­grat­ing from Fire­base to Su­pabase: the hard part is the data mod­el

Al­most every­one who mi­grates from Fire­base to Su­pabase un­der­es­ti­mates the same block: not auth, not stor­age, but re­shap­ing de­nor­malised Fire­store col­lec­tions into nor­malised Post­gres ta­bles with RLS. An hon­est ac­count of where the time and mon­ey ac­tu­al­ly burn — and which apps should not mi­grate at all.

What Su­pabase Re­al­ly Costs: An Hon­est TCO Look at Cloud vs Self-Host­ed

No ven­dor writes the TCO com­par­i­son be­tween Su­pabase Cloud and self-host­ed on Het­zn­er. Past a cer­tain us­age pro­file, self-host­ing saves real mon­ey — but only if you price your in­ter­nal op­er­at­ing hours at a real rate. Skip that, and the sav­ing is an ac­count­ing il­lu­sion.

Su­pabase as an AI back­end: pgvec­tor, Edge Func­tions and the con­sol­i­da­tion ques­tion

For most en­ter­prise use cas­es, a sep­a­rate vec­tor data­base is a prob­lem you buy back into your own stack. Why Su­pabase with pgvec­tor and Edge Func­tions is a con­sol­i­da­tion de­ci­sion, not a hype one — and where the hon­est lim­it ac­tu­al­ly sits.

Su­pabase or Fire­base: In Eu­rope, the Choice Is­n't a Fea­ture Ques­tion

Com­par­ing Su­pabase and Fire­base on fea­tures means com­par­ing the wrong di­men­sion. For Eu­ro­pean com­pa­nies un­der GDPR, this is a sov­er­eign­ty and risk de­ci­sion: a US cor­po­ra­tion un­der the CLOUD Act ver­sus open Post­greSQL with a real exit. A prac­ti­tion­er's take.

GDPR-Com­pli­ant AI on Your Web­site: What Works, What Does­n't

Su­pabase Row Lev­el Se­cu­ri­ty moves ac­cess con­trol out of ap­pli­ca­tion code and into the data­base.

For mul­ti-ten­ant SaaS, that is a ques­tion of risk and speed that be­longs on a de­ci­sion-mak­er's desk.
