Mobile Detect Light Bundle Laravel Package

Product Decisions This Supports

• Device-adaptive rendering vs. responsive-only. If the roadmap still includes an m-dot or device-specific template path, this bundle lets you branch in Twig ({% if is_mobile() %}-style checks) without standing up a full device-detection service. That makes it a cheap way to test whether server-side device branching is worth product investment before committing to a responsive rewrite.
• Prioritizing the responsive migration. By surfacing how many requests are actually hitting mobile-UA branches, you get real usage data to argue for (or against) consolidating on responsive design. The package itself is the instrument; the finding — "we're maintaining two template trees for X% of traffic" — is the decision input.
• Feature gating and fallback content. Mobile-specific CTAs, app-download banners, simplified checkout, or "your browser may not support this" messaging can be shipped as Twig conditionals rather than new backend endpoints. Low-effort experiments you can A/B.
• Analytics and experiment segmentation. Exposing device class to templates (and thus to client-side analytics tags) enables mobile/desktop cohort splits in experiments without a separate segmentation pipeline.
• Build vs. buy on the wrapper, not the detector. The underlying mobiledetect/mobiledetectlib is the real dependency. The bundle is a thin Twig integration, so the decision is "adopt a maintained library plus a 20-line extension" vs. "adopt this bundled wrapper." For most teams, that tips toward build.

When to Consider This Package

Consider it only if:

• You are actively maintaining a Symfony 2.x application and already have mobiledetect/mobiledetectlib in the dependency tree.
• You need Twig-level device checks today and want the shortest possible path — no new service class, no DI wiring.
• The alternative is worse: ad-hoc UA parsing scattered across controllers, or a third-party SaaS detection service with a contract.

Look elsewhere if:

• You are on Symfony 3.4+ / 4+ / 5+ / 6+. This bundle targets Symfony2, which reached end-of-life in 2018; compatibility is a real risk, and the wrapper adds no value over the underlying library.
• You care about maintenance signal. 2 stars, 0 dependents, and a near-zero health score mean no security response, no PHP 8 support guarantees, and no community to catch regressions. That's a governance problem, not just a code problem.
• Your product direction is responsive + progressive enhancement. UA sniffing is fragile (bot traffic, spoofed UAs, iPadOS reporting as desktop, privacy-preserving browsers). Modern equivalents — CSS media queries, feature detection, Sec-CH-UA-* Client Hints — are more durable and don't require a server-side dependency.
• You need detection for anything beyond coarse mobile/tablet/desktop (e.g., device model, OS version for support triage). Use the underlying library directly or a maintained alternative.

How to Pitch It (Stakeholders)

To executives: This is a small, MIT-licensed integration that lets us tailor web content by device without a platform migration. It's a tactical enabler, not a strategic bet — worth adopting only where we already run a legacy Symfony2 stack, and it should be treated as a short-lived bridge toward responsive design. Risk is low in blast radius (template-level) but non-trivial in maintenance (unmaintained dependency on an end-of-life framework); recommend scoping any adoption with a sunset date tied to the responsive migration.

To engineering: It's a thin Twig extension over mobiledetect/mobiledetectlib, pinned to Symfony2 conventions, with essentially no community adoption. Don't add it as a new dependency on a modern Symfony app — vendor the equivalent Twig extension in-house against the upstream library and get a maintained, testable seam. If you do adopt it, wrap it behind our own DeviceResolver interface so we can swap the detection strategy (UA → Client Hints → feature detection) without touching templates.
