Framer or a Custom Build? Choosing a Platform for Your SaaS Website
Nearly every version of this comparison is written by a studio that sells one side of it. We build both — here is how the decision actually goes, including where each runs out of road.
Almost every comparison of Framer against a custom build is published by a studio that only sells one of them. That is worth saying before anything else, because it explains why they all reach a confident conclusion and why the conclusions disagree.
We build both. This is the decision as we actually make it with clients, including the parts that argue against whichever one we would rather be selling that month.
The short answer
The choice is decided by who maintains the site after launch, and by what the site has to do that a page cannot. It is almost never decided by design ambition, which is the reason most people think they are choosing.
- Framer when a marketing team needs to ship and edit pages without a developer, and the site is a set of pages.
- Custom when the site must share code with the product, serve content from a database, or do something the platform does not do.
- Both is common and sensible: marketing pages on Framer, the app and anything data-driven custom.
If nobody on your team will touch the site after launch, and everything is going through a developer either way, Framer's main advantage does not apply to you.
What actually decides it
Five questions. In our experience they settle it, in this order.
1. Who edits the site in six months?
The single most predictive question, and the one least often asked.
If a marketer, founder or designer needs to add a page, change a headline or launch a campaign landing page without filing a ticket, Framer wins decisively. That is what it is for, and the alternative is a custom site where every copy change becomes a pull request — which in practice means changes stop happening. A site nobody can edit becomes a site nobody updates, and it decays.
If all changes will go through an engineer regardless, this advantage evaporates, and the decision moves to the other four questions.
2. Does the site need to share anything with the product?
Design system, components, authentication, a logged-in state, a dashboard preview with real data.
If yes, custom — usually in the same framework as the app. Two systems that must stay visually identical but live in different tools drift within months. Every design change is made twice, and the second one is late.
If the marketing site is genuinely separate from the product, this does not apply.
3. Is content coming from a database?
A blog, a docs site, a changelog, programmatic pages generated from data, anything with hundreds of entries.
Framer has a CMS and it is genuinely capable for a blog. It becomes strained when content is large, deeply relational, or generated from a source that is not the CMS itself. If your articles are written in the CMS, it is fine. If they are generated from your product's database or need relationships several levels deep, custom.
4. What does your compliance situation look like?
If you sell to enterprise, you will eventually be asked where the site is hosted, who has access, and what happens to visitor data. Framer's answers are Framer's answers, and for most companies they are perfectly acceptable — but they are not yours to change.
A custom build on infrastructure you control gives you answers you can adjust. If you have been through a security review that asked about your marketing site, you already know which side you are on.
5. How unusual is the design?
This one matters much less than people expect, which is why it is last.
Framer is capable of considerably more than most Framer sites suggest. Scroll effects, complex layouts and real motion are all achievable. The genuine ceilings are narrower than the reputation implies: custom canvas or WebGL work, unusual interaction models, and very fine control over exactly what loads when.
If your objection to Framer is "our design is too ambitious," it probably is not. If your objection is "we need a bespoke WebGL hero that streams product data," it is.
Side by side
| Framer | Custom build | |
|---|---|---|
| Time to first launch | Days to weeks | Weeks to months |
| Who can edit after launch | Anyone on the team | A developer |
| Cost shape | Ongoing subscription, low build cost | Higher build cost, low running cost |
| Design ceiling | High, with real limits at the edges | Whatever you can build |
| Performance | Good, largely out of your hands | Whatever you engineer, good or bad |
| Shares code with the product | No | Yes |
| Content at scale | Fine for a blog, strained beyond | Whatever you need |
| Hosting and data control | Framer's | Yours |
| Vendor risk | Real — pricing and terms are theirs | Yours to carry instead |
| Migration away | Difficult; export is not a full site | Difficult in a different way |
The last two rows are where the honest tension sits, and neither option escapes it. Framer means depending on a company whose pricing and roadmap you do not control. Custom means depending on your ability to keep engineers available to maintain it — which is its own dependency, and it fails quietly rather than with an email about a price change.
Where each runs out of road
Both, plainly.
Framer runs out when:
- The marketing site needs the product's authenticated state
- Content volume outgrows the CMS's relational model
- You need control over exactly what loads and when, at a level the platform does not expose
- Compliance requires answers about hosting you cannot give
- You need something genuinely bespoke — custom canvas rendering, unusual interaction models
Custom runs out when:
- Nobody has time to maintain it, and it silently goes stale
- Every copy change needs a deploy, so copy stops changing
- Marketing cannot ship a campaign page without a sprint
- The build cost consumed the budget that should have gone into content
- The team that built it left, and the next team does not want to touch it
That fourth custom failure is the most common and the least discussed. A beautifully engineered site with nothing new on it for a year loses to an ordinary site that publishes weekly — because search rewards the second one and buyers find it.
On performance
Worth being precise, because this argument is usually conducted on vibes.
Google's Core Web Vitals thresholds are Largest Contentful Paint under 2.5 seconds, Interaction to Next Paint under 200 milliseconds, and Cumulative Layout Shift under 0.1, each assessed at the 75th percentile of real page loads. Those are the numbers, and they apply identically to both options.
Framer sites generally hit them without special effort, because the platform handles image formats, sizing and delivery. The common failure is an enormous hero video or uncompressed imagery, which is a content decision rather than a platform one.
Custom sites can be faster than Framer — and are routinely slower, because performance is now your responsibility and it is easy to ship a heavy JavaScript bundle, unsized images and a font that shifts the layout on load. "We built it custom so it is fast" is an assertion, not a result. Measure it against those three numbers or the claim means nothing.
The combination most teams should consider
For a lot of SaaS companies the answer is not one or the other:
- Marketing pages on Framer — the team ships campaigns and edits copy without a developer
- The product custom — obviously
- The blog wherever it is easiest to publish — because the failure mode of a blog is not publishing, and whichever tool removes the most friction wins
The cost is two systems to keep visually consistent. That cost is real and worth naming: shared tokens, a documented type scale, and a habit of updating both when either changes. If nobody will own that discipline, pick one system.
How this fits a redesign
If you are choosing a platform as part of a rebuild, the platform question comes after the harder ones — what is currently working, whether you have a design problem or a positioning problem, and what must not break. Our redesign framework covers those, and the phased approach it describes works on either platform.
One platform-specific note: whichever you choose, keep your existing URLs. Migrating a site between platforms is the single most common way to lose rankings, and it happens because the new tool has different URL conventions and nobody mapped the old ones across.
Frequently asked questions
Is Framer good enough for a serious SaaS company?
Yes, for marketing sites. The limits are real but narrower than their reputation, and they sit at the edges — authenticated state, content at scale, bespoke rendering. If your site is a set of marketing pages and a blog, the platform is not what is holding it back.
Is a custom build always faster?
No. It is always capable of being faster, which is a different claim. Performance on a custom build is engineering work you have to actually do; Framer gives you a decent result by default. Plenty of custom SaaS sites fail Core Web Vitals while a Framer site on the same content passes.
What about SEO — does the platform matter?
Much less than the content does. Both can produce crawlable HTML, correct metadata, canonical URLs, structured data and a sitemap. Rankings follow content quality, relevance and links; the platform decides how much friction there is in publishing, which matters over a year but is not a ranking factor.
Can we start on Framer and move to custom later?
Yes, and many companies should. Framer to prove the positioning and ship quickly, custom when the constraints above start binding. Budget for the migration honestly — an export is not a working site, and the rebuild is close to a new build. Keep your URLs identical across the move.
What if we cannot decide?
Default to Framer if the site is marketing pages and your team wants to edit them. Default to custom if the site must share code with your product. If neither is clearly true, the decision matters less than you think, and the time spent deciding is better spent on what the pages actually say — which is what our guide to SaaS website design is about.
