A client portal for agencies and the teams they serve. Project status, async approvals, file delivery, and Stripe-backed billing — all in one workspace.
A component library application. Browse, preview, and copy production-ready Webflow embeds and React components with live previews and one-click copy.
A Webflow-native AI co-builder trained on our patterns and embed library. Generate animation timelines, debug class conflicts, translate Figma to embeds.
Production-grade applications, internal tools, and SaaS platforms on a modern TypeScript stack. Eight to twelve week sprints with full code ownership at handover.
Pixel-honest Webflow sites with hand-rolled GSAP animations, Lenis smooth scroll, and embedded systems tuned to platform limits. Dark mode and accessibility included.

Company
Stacklumen is a full-service web and app development company specializing exclusively in Webflow, Shopify, and Custom Code solutions. No mystery. No ambiguity. Just great work, done with the right tools, for the right clients.
We made a deliberate choice to specialize instead of generalize. The web development landscape is crowded with generalists. We chose a different path.
The web development landscape is crowded with generalists who do a little of everything reasonably well. We chose a different path — deep expertise in the best tools available for building modern, scalable web experiences.
That choice means our clients get teams who know their tools inside and out — not developers learning on the job. Faster delivery, fewer bugs, and solutions that hold up over time.
The most powerful visual development platform available. Developer-level control without sacrificing speed — producing clean, semantic code. Our primary build environment for marketing sites, landing pages, and content-driven experiences.
For clients who sell online, Shopify is the industry benchmark. Battle-tested infrastructure, vast ecosystem, and unmatched performance at scale. We build custom themes and storefronts that convert — not cookie-cutter templates.
Sometimes the platform needs to bend to the product. Our custom code capability means no constraint is final — from GSAP animations to bespoke JavaScript integrations, we build what no template can.
Small businesses, emerging brands, and growth-stage companies across the US who understand their website is an investment. We work best with clients who value craft, communicate clearly, and want a long-term digital partner.
Every tool in our stack was chosen deliberately. We invest deeply in platforms with proven track records and the performance our clients demand.
We integrate the platforms our clients already use — or help them identify the right tools. From CRMs to dropshipping, we connect the dots.
Every tool we recommend passes the same internal filter. No exceptions.
If it's slow, it's wrong. Every platform must meet our baseline standards for load time, reliability, and uptime. We don't build on shaky ground.
Every site we build, you own. We favor platforms that give clients direct access to their data and code without requiring us as a permanent middleman.
We don't build on platforms that might not exist in three years. Everything in our stack has strong funding, strong ecosystems, and proven staying power.
We don't push tools we get commissions on. If Webflow isn't right for your project, we'll say so. Honesty builds better partnerships.
We match tools to problems, not problems to tools. Platform decisions are based on what's right for your project — not what's easiest for us.
You'll always know what we're building, why, and what it costs to maintain. No hidden decisions. No surprise dependencies. That's why this page exists.
