About Campnab and Diffyn

In their own words, as submitted to SaaSHub.

Campnab
Diffyn

Popular campgrounds open for reservations months in advance—and sell out in minutes. But many of those campsite reservations get canceled. So, we built an app that scans sold-out parks for new availabilities and sends notifications about them. Since we did, we’ve helped campers all over North...

Questions & Answers

As answered by people managing Campnab and Diffyn.

What makes your product unique?

Campnab's answer

Campnab scans sold-out state, provincial, national, and some county parks for cancelled campsite reservations and permits. When it spots an opening that matches your requirements, it sends a text message to you about the new availability.

Diffyn's answer:

Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.

Why should a person choose your product over its competitors?

Campnab's answer

We monitor parks throughout the US and Canada—and can check for backcountry availabilities in a number of these parks. Using Campnab is super-easy as we’ve put so much effort into making the interface clean and intuitive. Plus, it has all kinds of useful features (for example: the ability to scan only for specific campsites). Meanwhile, if you ever run into an issue, one of us will help resolve it one-on-one. Members tend to be pleased that a real human is ready to lend a hand when needed.

Diffyn's answer:

Diffyn is the platform that specializes on both change management and multi-model analysis.

How would you describe the primary audience of your product?

Campnab's answer

A lot of seasonal campers use Campnab throughout the spring, summer, and early fall. That said, we also do see a number of full-time RVers sign up for annual plans, as they need to be able to find campsite reservations year-round. We also find that some fair-weather campers use our pay-per-use scans once or twice a year.

Diffyn's answer:

Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.

What's the story behind your product?

Campnab's answer

Eric and Kim bought a campervan, but couldn’t find a place to camp as every park was sold-out. This led Kim to spend hours hitting Refresh on the parks’ booking site in hopes of finding an availability. Eric figured he could automate the process to save Kim some time—and realized that others might also like this sort of service. So, he and his friend (also named Eric) released the product publicly. Since then, Campnab has become our full-time job, as we work to keep the system running well, add new features, and introduce scanning for additional regions.

Diffyn's answer:

I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.

Which are the primary technologies used for building your product?

Diffyn's answer:

React, Next.js, POSTGRESQL

    I've used Campnab twice and was able to secure great campsites in my desired location both times. Both were for very busy weekends and I wouldn't have been able to snag a campsite otherwise. Love this service so much!

    I recommend this app to anyone that likes camping and will definitely use it in the future. I was interested in camping in Canyonlands National Park, UT, but it was solid booked at least 6 months in advance. Though a...
