As answered by people managing ConfigCat and ClientForms.app.
ConfigCat's answer
ConfigCat makes feature flag management simple, affordable, and accessible to teams of all sizes.
What sets ConfigCat apart?
ConfigCat combines the capabilities development teams need with the simplicity and pricing that make feature flag management accessible.
ClientForms.app's answer:
Neurodivergent-first design. Most digital forms just replicate paper online. ClientForms is built specifically for ADHD and autism patients - progress bars with time remaining (helps with time blindness), softer colours instead of harsh white, sticky headers so you always know where you are. The forms are designed to reduce anxiety and improve completion rates.
ConfigCat's answer
ConfigCat is built for software development teams that want to release features faster and more safely.
Our users include:
ConfigCat works for teams of all sizes, from individual developers to large organizations in regulated industries such as banking, finance, and healthcare.
ClientForms.app's answer:
Psychologists who assess ADHD and autism. Typically private practice, solo or small group (1-5 clinicians), currently using paper forms and spending hours on admin per assessment. They want something that works and is secure.
ConfigCat's answer
If you're looking for a LaunchDarkly, Unleash, or Split alternative, ConfigCat offers a simpler approach to feature flag management without sacrificing essential capabilities.
You get gradual rollouts, advanced targeting, unlimited team members, SDKs for popular programming languages, and enterprise-ready security features.
Unlike platforms that charge per seat, ConfigCat lets your entire team collaborate without additional user fees. Its transparent pricing makes costs easier to predict as your product grows.
And if you need help, you'll get responsive, personal support from people who know the product inside out.
Whether you're starting with feature flags or migrating from another platform, ConfigCat makes the transition straightforward.
ClientForms.app's answer:
Most clinical software treats patients as an afterthought. ClientForms is designed specifically for neurodivergent users who are filling out the forms, progress indicators, time estimates, calmer colours, predictable layouts. One link, no signup required, works on any device. Patients just open and complete.
ConfigCat's answer
ConfigCat started in 2018 when a small team of developers set out to solve a problem they'd experienced firsthand: changing application behavior shouldn't always require a new deployment.
The company was bootstrapped from day one, with the founders leaving their jobs to build a feature management platform that was simple, reliable, and affordable.
The first year wasn't easy. ConfigCat didn't get its first paying customer until 2019. But gradually, developers began discovering the platform, appreciating its straightforward approach and transparent pricing.
What started as a small engineering project grew into a feature flag platform trusted by development teams around the world.
Despite that growth, the original philosophy hasn't changed: powerful tools don't have to be complicated, and great customer support should be part of the experience.
ConfigCat's answer
ConfigCat is built using technologies including:
ConfigCat also provides open-source SDKs for popular programming languages and frameworks, enabling fast, local feature flag evaluation without requiring a network request for every flag check.
ClientForms.app's answer:
Frontend: Next.js 15 (React 19), Tailwind CSS Backend: Supabase (PostgreSQL, Row-Level Security) Authentication: Clerk Payments: Stripe Hosting: Vercel (Sydney region) Database hosting: Supabase (Australian data residency)
