Questions & Answers

As answered by people managing kdiff3 and FixyFlow.

What makes your product unique?

FixyFlow's answer:

FixyFlow does one thing — customer communication — and runs alongside whatever you already use (Jobber, RepairShopr, Shop-Ware, Tekmetric, or pen and paper). Most shop management tools try to replace your entire workflow. FixyFlow just owns the SMS, tracking page, and review-ask layer so customers stop calling to ask "is it ready yet?" — no data sync, no double entry, setup in under 5 minutes.

Why should a person choose your product over its competitors?

FixyFlow's answer:

Three reasons. (1) No migration — FixyFlow sits beside your existing tools instead of replacing them, so you don't retrain staff or move data. (2) Priced for solo operators at $15/mo rather than $150–300/mo for full shop management suites. (3) Direct founder support — emails reach a real person, not a ticket queue. The free trial is 14 days, no credit card, and setup takes under 5 minutes.

How would you describe the primary audience of your product?

FixyFlow's answer:

Small service business owners running 5–200 work orders a month: phone and electronics repair, auto repair andcollision, dry cleaners and tailors, HVAC and plumbing, jewelers and locksmiths, bicycle and furniture repair, appliance service. Particularly strong fit for "first CRM" customers — shops still tracking jobs in a notebook or spreadsheet and drowning in status phone calls.

What's the story behind your product?

FixyFlow's answer:

I (Lasse) used to own a computer repair shop and spent a lot of time on admin/following up on customers, playing phone tag and getting interrupted during repairs. So I decided to do something about it, I wanted an elegant, simple solution that allows both the customer to be delighted as well as saves time and money for the service business. So I created what I like to call the "customer happiness layer" FixyFlow!

Which are the primary technologies used for building your product?

FixyFlow's answer:

Next.js 15 (App Router) + TypeScript + React + Tailwind CSS on the frontend. Drizzle ORM with Postgres (Supabase) for the database.
