Challenges with Builder.io
Key pain points
Builder.io looks impressive in demos but the reality of day-to-day usage tells a different story. The editor can be laggy, especially with more than 30 components on a page, and we have seen reports of outright crashes that lose unsaved work. The documentation is a persistent sore point. Developers on forums describe spending days trying to get basic integrations working because the docs are outdated or incomplete. For an agency setting up projects for clients, unreliable documentation means unpredictable timelines.
Pricing is another area where Builder.io catches teams off guard. The free tier exists but is quite limited, and costs ramp up quickly once you need features like roles, scheduling, or higher usage limits. We have seen complaints from freelancers and small teams about unexpected charges and slow support response times when trying to resolve billing issues. The lack of self-hosting is also a hard blocker for some clients with strict data residency requirements.
The biggest concern from our perspective is vendor lock-in. Builder.io's SDKs are deeply embedded in your frontend code, and if you ever need to migrate away, you are essentially rebuilding your page composition layer from scratch. There is also no real-time collaboration, so two editors working on the same page can overwrite each other's changes without warning.
Editor performance and stability
The visual editor becomes laggy with complex pages and has been reported to crash, losing unsaved work. Teams with content-heavy pages will feel this friction daily.
Outdated and incomplete documentation
Developers consistently report that the docs are confusing, outdated, or missing critical steps. Getting started takes far longer than it should for a tool that sells itself on speed.
Vendor lock-in risk
Builder.io's SDKs are tightly coupled to your frontend. Migrating away means rebuilding your entire page building and composition layer from scratch.
Limited collaboration tools
Builder.io now offers branching and peer review workflows in its Fusion product, but true real-time co-editing is still missing. Editors working outside of the Projects workflow can still overwrite each other's changes.
Pricing escalation
Costs ramp up quickly beyond the free tier, and teams report unexpected charges. Basic features like roles and scheduling sit behind higher-priced plans.
Slow and unresponsive support
Multiple users report delayed support responses, unresolved tickets, and difficulty getting refunds or cancellations processed in a reasonable timeframe.
Benefits of Joomla
Key advantages
Recommending Joomla in 2026 feels a bit like recommending Internet Explorer. But if you must use it, it does earn a few real points. The multilingual support is built in, so you run a five-language site without a pile of plugins. The access-control system is more detailed than most enterprise platforms, and the modular structure gives developers room to build complex, multi-section sites. If you have a big editorial team that needs genuinely granular permissions, Joomla holds up.
If you are set on Joomla and we cannot talk you out of it, we will point you to an agency that still happily ships heavy old templates. Or sit down with us for half an hour, and we will at least make sure you do not regret the journey.
Native multilingual support
Joomla ships with multilingual features baked in, so you don’t need a plugin graveyard just to run a site in five languages. It handles translations cleanly and is one of the few CMS platforms that gets this right out of the box.
Granular user permission system
Its ACL system is its biggest bragging right. You can lock down roles, workflows, and access rules with a level of control that most CMS platforms still envy.
Custom field capabilities
Joomla gives you solid flexibility with custom fields, letting you shape structured content without hacking together a dozen extensions. It’s powerful enough for complex layouts and multi-section content.
Active developer community
The community isn’t massive, but the people who are there are dedicated, technical, and still shipping useful extensions and documentation. If you're deep in Joomla land, it’s a lifeline.
Strong security foundation
Kept patched, Joomla is stable and the core team takes security seriously, with regular updates. The catch is the "kept patched" part. The 2026 JCE editor exploit hit sites that fell behind, so the upkeep is on you.
Modular architecture flexibility
Its module-based layout system lets you build multi-section portals, dashboards, and content-heavy sites without bending the platform backward. If you know what you're doing, it’s flexible enough to scale.
Common questions
Builder.io to Joomla migration FAQs
Answers to the most common questions about Builder.io to Joomla migration
Can you migrate from Builder.io without losing your page designs?
Yes, but it takes work. Builder.io's visual editor stores page compositions as JSON that references your registered components. Those component registrations are tightly coupled to Builder's SDK, so you can't just export and import elsewhere. What you can preserve is the design itself. We extract the page structures, map them to equivalent components in the new system, and rebuild the composition layer. The visual output stays the same. Typical timeline is 6-10 weeks depending on how many page types and custom components are involved. The biggest time sink is usually recreating A/B test variants and personalisation rules that lived inside Builder's platform.
What does Builder.io actually cost?
Builder.io's free tier gives you 1 user and basic features, which is enough to evaluate but not to run a real project. The Growth plan starts at $49/month and includes more seats and content types. Beyond that, pricing gets opaque. Teams needing roles, scheduling, and higher API limits are pushed toward custom Enterprise plans that typically start in the $500-$1,000/month range. We've heard from freelancers and small agencies who were caught off guard by charges after exceeding limits on the Growth plan. Builder.io also charges per "impression" on higher tiers, which means your costs scale with traffic in ways that aren't always predictable.
How does Builder.io compare to a traditional headless CMS?
Builder.io is a visual page builder first and a CMS second. That distinction matters. If your primary goal is letting marketing teams build landing pages without developer involvement, Builder.io does that well. If you need structured content modelling, editorial workflows, multi-language support, or content that powers more than just web pages, a traditional headless CMS is a better fit. Builder.io's SDK embeds deeply into your frontend code, which creates vendor lock-in that most headless CMS platforms avoid. We typically recommend Builder.io only when the use case is narrow: high-volume landing page creation for marketing teams. For everything else, a headless CMS with a proper content model gives you more flexibility long-term.
What's the main risk of building on Builder.io?
Vendor lock-in. Builder.io's SDKs are woven into your component rendering layer, which means migrating away requires rebuilding how your pages are composed and rendered. That's not a content migration, it's an architecture migration. With a typical headless CMS, your content is accessible through standard APIs and your frontend is independent. With Builder.io, the two are intertwined. We've worked with teams who spent months extracting themselves from Builder.io because every page template needed to be recreated outside the platform. If you're evaluating Builder.io, go in with eyes open about the exit cost.
Is Joomla free?
Yes. Joomla is open-source software under the GPL, so there is no licence fee and you can download Joomla 6 and self-host it for nothing. The real cost is everything around it. You pay for hosting, for any commercial extensions and templates you bring in, and for the developer time that keeps it patched and upgraded. Treat the price tag as hosting plus extensions plus maintenance, not a SaaS subscription. On a busy site those running costs add up fast, which is the part most "Joomla is free" claims quietly skip.
Can I migrate from Joomla to Sanity?
Yes, and it tends to be cleaner than a Joomla version upgrade. Joomla stores everything in MySQL, so we script the content extraction, map your articles, categories, and custom fields into a Sanity content model, and rebuild the frontend in Next.js. For a typical site of 500 to 2,000 pages, budget 6 to 12 weeks. The extraction takes a few days. The rest goes on the new frontend, replacing whatever your extensions used to do, and mapping 301 redirects so you keep your search rankings. The payoff is no more PHP version juggling and no near-rebuild every time the platform bumps a major version.
What are Joomla's main limitations?
Three things bite. First, major upgrades are brutal. Joomla 3 and 4 both reached end of life in October 2025, so anyone still on them is running unpatched software, and moving up a major version often breaks extensions and templates badly enough to feel like a rebuild. Second, the extension and template ecosystem is small next to WordPress, and maintainers keep drifting away. Third, the developer experience is dated and the admin panel is hard to navigate, so editor productivity suffers. Security upkeep is on you too, as the JCE editor exploit doing the rounds in 2026 reminded plenty of sites.
Joomla vs WordPress vs headless, which should I pick?
For a content site you want to keep cheap and simple, WordPress wins on ecosystem size and the sheer number of developers who know it. Joomla's honest edges are native multilingual and its access-control system, so it makes sense if you genuinely need granular permissions across a big editorial team. But both are PHP monoliths that tie your content to your frontend. If you care about performance, want a modern build with React or Next.js, and plan to push content to a web app, a mobile app, and a few other places at once, go headless. We pair Sanity with Next.js for exactly that, and it is where most teams leaving Joomla end up.
