Production-grade web work.
And four shipped products.
Stacklumen is a software and web development company. We build Webflow sites, ship custom applications, and run four products of our own.
Webflow, engineered like software.
Our core practice. Pixel-honest builds, custom embeds, and animation systems treated with the same rigor as production codebases.
Custom Webflow Builds
Custom Webflow sites with hand-rolled GSAP animations, Lenis smooth scroll, Finsweet integrations, and embedded systems that stay under platform limits without compromise.
- +GSAP animation systems & ScrollTrigger
- +Finsweet CMS, Attributes, & Relume integration
- +Custom embeds optimized to fit the 50KB limit
- +Dark mode, responsive grids, accessibility audits
Migration & Rebuilds
Modernize legacy Webflow sites or migrate from Wix, Squarespace, and WordPress without losing SEO equity.
Webflow on Retainer
Monthly hours for ongoing CMS work, A/B tests, and feature additions. Direct Slack channel.
Four products. All shipped.
Baselumen, Kitlumen and Hublumen are live and paid, and the Stacklumen App is shipped — all born from the patterns we use on every client engagement. Stacklumen AI follows next.
Baselumen
A production toolkit for Webflow, live at baselumen.com. Browse, preview, and copy production-ready embeds and components developed across our agency work — every token is a CSS variable, so nothing locks you in.
- +Webflow embeds with live previews & one-click copy
- +React + TypeScript components, Radix-backed
- +GSAP & Lenis animation patterns
- +Finsweet integration recipes
Hublumen
A client portal for agencies and the teams they serve. Project status, async approvals, file delivery, and Stripe-backed billing — all in one workspace.
- +Live milestone tracking with staging URLs
- +In-context feedback tied to deliverables
- +Version-tracked file delivery
- +Stripe invoicing & payment status
Kitlumen
Browser-based web tools for SEO, AEO, schema and accessibility work, live at kitlumen.com. The same utilities we run on every engagement — audit a page, generate schema markup, preview Open Graph, check contrast — with nothing to install.
Stacklumen AI
A Webflow-native AI co-builder trained on our patterns and embed library. Generate animation timelines, debug class conflicts, translate Figma into shippable embeds. Enablement engagements are open now; the co-builder ships after the portal and Baselumen reach public availability.
From idea to launch, end-to-end.
Strategy, design, and engineering under one roof. Production-grade applications shipped on tight timelines.
Product Sprints
8–12 week engagements for SaaS, marketplaces, and internal tools. We embed with founders and product teams to ship complete applications — design system, infrastructure, and admin tooling included.
- +Discovery, design, and engineering as one team
- +Production-grade auth, billing, and admin from day one
- +CI/CD, observability, and infrastructure as code
- +Knowledge transfer and 60 days of support included
Shopify Builds
Custom Liquid themes and conversion-tuned ecommerce experiences for DTC brands.
Agency Partnerships
White-label dev capacity for design agencies. Your brand and client, our engineering behind the scenes.
Opinionated tools, every time.
We’re opinionated about tools because they shape outcomes. This is the stack we reach for on every engagement.
A process that respects your time.
No bloated discovery decks. No surprise scope. Clear milestones, weekly demos, and code you own from day one.
Scope & strategy
A focused intro call, written brief, and fixed proposal within 72 hours.
Design in motion
Static comps are dead. We design in Figma and prototype in code.
Ship weekly
Weekly demos on a staging URL. Feedback in-context, never “the reveal.”
Handover
Full code ownership, written documentation, 60 days of post-launch support.
Quietly shipping work that compounds.
A small team, but one that delivers. The numbers we care about most — built one project at a time.
Let’s build something good.
