A premium template is an unusual purchase: you are buying a codebase you cannot fully inspect before paying, that you will then live inside for months. A bad one is not a wasted $79 — it is weeks of fighting someone else's decisions.
Here is how to tell them apart.
Code quality signals
You usually get a live demo and screenshots, not the repository. That is still enough to learn a lot.
Open the demo and view source. Is the HTML semantic — real headings, landmarks, buttons that are buttons? Or a wall of divs? The markup you can see reflects the code you cannot.
Run Lighthouse on the demo. If the author's own showcase, with no real data, scores poorly on performance and accessibility, that is the best case you will ever see. Yours will be slower.
Check the demo's behaviour. Resize to mobile. Tab through with the keyboard — does focus stay visible and logical? Toggle dark mode if offered and look for unreadable text. These take three minutes and are strongly predictive.
Read the documentation before buying. It is usually public. Good docs show project structure, environment setup, how to add a page, and how to change the theme. Thin docs are not only a docs problem; they signal how much care went into everything else.
How deep the TypeScript really goes
"TypeScript" on a listing can mean very different things.
Surface-level: files are .tsx, and any is everywhere. You get syntax and none of the safety.
Genuine: typed API responses, typed database models, discriminated unions for state, generics where they help. Refactors become safe and the editor actually knows what things are.
You often cannot verify this pre-purchase, but proxies help: does the documentation show typed examples? Does the author mention strict mode? Are there type definitions in the feature list? If the demo ships source maps, the bundled code can be revealing.
Test and documentation coverage
Most commercial templates have no tests. That is the market norm, and it is a real cost — every upgrade is a manual regression hunt.
If a template does have meaningful tests, weight it heavily. It says the author expects the code to change and intends to keep it working.
For documentation, look for: setup, configuration, deployment, how to extend, and a troubleshooting section. Troubleshooting is the tell — it only exists when an author has supported real users through real problems.
Update cadence
The single best predictor of whether you will regret this in a year.
Check the changelog. What you want is regular, dated, substantive entries — dependency updates, framework version bumps, bug fixes. What you do not want is an initial release, one patch two weeks later, then eighteen months of nothing.
Front-end templates decay quickly. A Next.js template that has not been touched since two major versions ago is a migration project you are paying for.
Ask specifically: has it been updated for the current major version of the framework? If the answer is "coming soon", treat that as no.
License terms: regular vs extended
Read this before buying, not after your first client asks.
The usual split:
Regular / single — one project, non-commercial or internal, or a project you do not charge end users for
Extended / commercial — a project where end users pay, or one you resell
The distinction that catches people: "one project" almost always means one end product. Building the same template for five clients requires five licences. Reselling or redistributing the source is nearly always prohibited under both tiers.
Also check: is the licence perpetual? Do updates continue after the support window ends? Can you use it after a subscription lapses? For a business asset, a perpetual licence with time-limited support is much safer than access that disappears with a subscription.
Support expectations
"6 months support" usually covers bugs and questions about the template as delivered. It does not cover customisation, your hosting, third-party services, or teaching you the framework.
Set expectations accordingly. Before buying, look at the author's public comment threads: are questions answered? How quickly? Are the answers substantive or deflections? The support you can observe is the support you will get.
Red flags
No changelog, or an abandoned one
A demo that is slow or breaks on mobile
Screenshots only, no live demo — always a bad sign
Reviews mentioning unanswered support
Dependencies on deprecated libraries — check the tech list against what is current
"Lifetime updates" with no update history — a promise, not a track record
No refund policy
An author with one product and no history — not disqualifying, but raises the bar on everything else
The buying decision
Ask three questions:
How much time does this save? Multiply the honest number of days by your rate. That is the real budget, and it is almost always far above the sticker price — which is why obsessing over $49 versus $99 is the wrong axis.
How close is it to what I need? A template at 80% fit is a gift. At 40%, you will fight it, and starting fresh would have been faster.
Will it still be maintained in a year? Update cadence answers this better than anything else.
If two and three look good, buy the more expensive one. The difference between templates is measured in weeks of your time, not in tens of dollars.
