Every template on this page is designed and maintained in-house by uiCookies, so what you download is our own work rather than a link to someone else's theme. The set covers two kinds of technology business. Nexus is for companies that sell IT services and software development. Stratos, Ledgerline, Launchpad and Abacus are product sites for SaaS and software companies, ranging from a seven-page suite with a dashboard to a single launch page.
A technology company's site is often judged by people who know what good software looks like. They want to understand what you build or sell from the first screen, see the product or the delivery process rather than a stock photo of a laptop, and find pricing or engagement terms without booking a call first. Proof carries as much weight as polish: case studies, metrics, integrations and, for developer buyers, a real code sample. After that there should be one clear next step, whether it is a scoping call, a free trial or an email sign-up.
All five are static HTML, CSS and JavaScript with no build step: unzip, open index.html and start editing. They are not all the same generation. Nexus, Launchpad and Abacus run on Bootstrap 5 with vanilla JavaScript and no jQuery. Stratos and Ledgerline are built on Bootstrap 6, which is still in alpha; the framework is vendored at a pinned commit and targets evergreen browsers only, so treat those two as a head start on v6 rather than a foundation for a site you need to maintain today. Every template is free for personal and commercial use, including client work, under the standard uiCookies licence, and attribution is optional but always welcome (the full terms are at uicookies.com/license). Each has a live demo and a download page.
The templates
Nexus
Nexus is the services-company template in this set, written for IT firms, managed service providers, software development agencies and cloud, DevOps or cybersecurity consultancies. Its homepage sets out six practices (web and app development, cloud and DevOps, cybersecurity, data and AI, UI/UX design, IT consulting), a four-step delivery model, a metrics band, three case studies, tech-stack chips, a team row, three engagement tiers and a contact section for booking a scoping call. A second Services & Process page goes deeper with a five-stage delivery timeline, the engagement models and an FAQ.
Dark gradient-mesh hero and CTA bands carry a product-UI mockup drawn in pure CSS, in near-black indigo with violet and cyan accents and Space Grotesk over Inter. Metrics count up on scroll and the mobile menu is an off-canvas drawer. It runs on self-hosted Bootstrap 5 with vanilla JavaScript and no jQuery; the contact form validates inline but sends nothing until you connect it to a backend.
Stratos
Stratos gives a SaaS team both the marketing site and the product UI in seven pages. The landing page covers features, use cases, integrations, a four-step onboarding sequence, per-seat pricing across three plans, a how-we-compare section and an FAQ. Alongside it come an application dashboard with throughput, plan usage and recent releases, a pricing page, a long-form blog post, a 404 page and two showcase pages that work through the components and form controls, which suits a team that wants one design system across the website and the app.
It is built on Bootstrap 6 alpha, vendored at a pinned commit, and uses components Bootstrap 5 never had, including Combobox, Datepicker, OTP input, password strength and chip input. Dialogs and drawers use the native dialog element, dark mode is remembered across visits, and the JavaScript is ESM-only with no jQuery. It needs Safari 16.4+, Chrome 111+ or Firefox 113+.
Ledgerline
Ledgerline suits fintech, payments-infrastructure and usage-priced SaaS companies. Its split hero pairs the headline with a live payments feed built in CSS rather than a screenshot, followed by a logo band, three product primitives (payments, payouts and a ledger API), a syntax-highlighted request-and-response sample, an embedded pricing calculator, a figures band, a security section with a compliance list and three testimonials. The pricing page carries the full calculator, a ten-row plan comparison table that stacks properly on phones and a six-question FAQ about fees.
The calculator is the reason to choose it. Two sliders, payments per month and average payment, update each plan's monthly total and effective rate, badge whichever plan is cheapest (the free one included) and work out where the next plan takes over, all from one plan list. Tabular numerals keep figures aligned. Bootstrap 6 alpha, ESM-only vanilla JavaScript, light and dark mode.
Launchpad
Launchpad is a one-page landing template for a SaaS product or a web or mobile app that is about to ship; its demo copy sells a release-management tool. The hero is a release cockpit built in HTML and CSS, with KPI tiles, staged-rollout bars, a spark line and a floating status toast. After it come a six-card feature grid, a three-step how-it-works band with a code chip, a ten-tile integrations grid, animated stat counters, three pricing tiers with one highlighted, an FAQ and an email-capture form.
A monthly/annual toggle swaps every price, although it is a display switch and does not connect to billing. Icons are hand-drawn inline SVG rather than an icon font, the FAQ is a keyboard-friendly single-open accordion, and there is a skip link and a slide-in mobile nav. Bootstrap 5, vanilla JavaScript, no jQuery, which also keeps it workable on strict-CSP hosts.
Abacus
Abacus targets an accounting, invoicing or bookkeeping SaaS sold to small businesses, and its single page also fits other B2B finance tools. Above the fold sits a dashboard mock: a CSS-built app window with stat tiles, an invoice list and a revenue-versus-expenses chart, so the product looks real before anyone scrolls. Below it are six feature cards (invoicing, expenses, reports, bank reconciliation, tax and VAT, multi-currency), a tabbed product tour, an integrations grid, three pricing tiers, testimonials, an FAQ and a CTA band with an email field.
Cobalt and marigold on warm-oat paper, a columnar-ledger motif and JetBrains Mono figures give it a bookkeeping feel. The tour's tabs are keyboard-navigable, the pricing toggle rewrites monthly and annual prices, and trust stats count up on scroll. It is Bootstrap 5 with vanilla JavaScript and no jQuery; the chart is drawn with Chart.js from static sample data.

How to choose
Start with what the company sells. If it sells people and expertise, such as projects, retainers or managed services, Nexus is the template built for that, with practices, a delivery process, case studies and engagement tiers. If it sells a product, choose by how much site you need. Launchpad covers a single-page launch, and Abacus does the same for finance or back-office tools where showing the dashboard does the persuading. Ledgerline fits usage-priced products where the pricing maths is the pitch. Stratos is the broadest, adding a dashboard, blog post and pricing page, but like Ledgerline it is a Bootstrap 6 alpha build. If you need a site to run for years on a stable release, pick one of the Bootstrap 5 templates.
If you came looking for a startup, technology or mobile app template, Launchpad and Nexus cover most of that, and Launchpad's HTML-and-CSS hero can be swapped for your own app screens. We do not have a dedicated web-hosting or computer-repair template. For hosting, Launchpad adapts best: three tiers, a monthly/annual toggle, a feature grid and an FAQ are most of a hosting plans page, and Stratos adds a comparison section and a separate pricing page if you need more room. For a computer repair business, Nexus is the closest fit. Rename its six practice cards to your repair services, turn the delivery steps into drop-off to collection, and connect the contact form to your inbox.
Frequently asked questions
Should I build a production SaaS site on the Bootstrap 6 templates?
Stratos and Ledgerline use Bootstrap 6 alpha, vendored at a pinned commit so nothing changes underneath you. Bootstrap 6 has not been released and the framework is still changing, so they are best treated as a head start on v6 rather than a foundation you need to maintain today. They also target evergreen browsers only: Safari 16.4+, Chrome 111+ and Firefox 113+. For a stable base, Nexus, Launchpad and Abacus run on Bootstrap 5.
Can I replace the product mockups with my own app?
Yes. The mockups in Nexus, Ledgerline, Launchpad and Abacus are built in HTML and CSS rather than screenshots, so you edit the numbers and labels directly and they stay sharp at any screen size. Abacus's chart reads static sample data in the page, which you can swap for your own. If you prefer a real screenshot, drop it into the hero in place of the mock.
Do the pricing calculators and toggles connect to billing?
No. The monthly/annual toggles in Launchpad and Abacus only change the prices on screen, and Ledgerline's calculator compares plans in the browser from the plan list in the page. Edit that list and the prices to match your own tiers, then point the sign-up or checkout buttons at your billing provider.
Will the trial sign-up, email capture and contact forms collect leads?
Not until you connect them. The forms work in the browser, and most validate entries, but they send nothing on their own. Point them at a form service, your CRM, a mailing tool or your product's sign-up endpoint before launch.
Can I use these for a client's software company or my own product?
Yes. Every template here is free for personal and commercial use, including client work, under the standard uiCookies licence. Attribution is optional but always welcome, and the full terms are at uicookies.com/license.
