Zen
Three reference sites for one client.
StackZen prices AI and SaaS tools, ForxZen adds up what a forex or CFD trade costs, and KripZen grades how safely crypto exchanges hold your money. We redesigned each one around a single idea, built the paths from first question to final comparison, and wrote the trust pages natively in every language.
Client work. The three sites belong to one client; ThirteenTabs designed and built them.
Three sites
One client, three subjects where readers are easy to mislead. Each site got its own concept, so no page could be mistaken for the other two.
-
StackZen
The Tally. Every tool's pricing ends in the yearly bill for your team, set like a till receipt.
- A redesign around the receipt: plans, limits and seat counts for 34 AI and SaaS tools, read from each vendor's own pricing page
- Paths from the price list to tool pages, head-to-heads and alternatives
- Trust pages, including how prices are checked, written natively in each language
- Languages
- English, Turkish, Russian
- Lighthouse, mobile
- Performance 96–99, accessibility 100
-
ForxZen
The rate board. Spread, commission and overnight swap add up on a split-flap board, so the cost of one trade is a number you can read.
- A redesign around the board: cost calculators that show what a trade takes out of your account and how far price must move to break even
- Paths from the calculators to the glossary, guides and a broker reference built on regulator registers
- Trust pages, including how brokers are reviewed, written natively in each language
- Languages
- English, German, Spanish, Brazilian Portuguese, Turkish, Russian, Azerbaijani, Thai
- Lighthouse, mobile
- Performance 91–98, accessibility 100
-
KripZen
The Rating Seal. Each exchange gets a report like a ratings agency's, with a seal whose rings are the weighted checks behind its grade.
- A redesign around the seal: exchanges graded A to F on proof of reserves, custody, regulation, insurance and incident history, every fee and licence linked to its source
- Paths from the grades to side-by-side comparisons and full exchange reports
- Trust pages, including how exchanges are graded and how the site earns, written natively in each language
- Languages
- English, German, Spanish, Brazilian Portuguese, Turkish, Russian, Azerbaijani, Thai
- Lighthouse, mobile
- Performance 98–100, accessibility 100
How we measured
The scores above are ranges, not a best run. Each range is the lowest and highest Lighthouse mobile score across the sites' main page types (home, listings, detail pages, calculators and guides), run in October 2026 after the redesigns shipped. We do not publish the client's traffic or revenue.
