just so you know, Freebee version 1.2.1 hit the App Store on iPhone, with fixes to annoying UI problems (the refresh spinner now is not obscured by the search bar!)

Another project I enjoyed working on this year (in collaboration with the amazing Idan Alon, Tamar Aviv, Noa Gross and Yael Molkandov) was DriveOn (stylized as Drive⏻n), a prototype for a car rental service laid out in Figma and vibe-coded using Claude Design. 

\n

DriveOn features two main flows, for users wishing to rent a car (37 screens), and for users wishing to list their car (16 screens). The project utilizes responsove design via Autolayouts, uses a consistent color palette and type selection stored as variables, and includes a UI style reminiscent of Neuomorphism and Apple’s Liquid Glass.

First up, I wrote (as part of a web development course) with a few friends (namely. in alphabetical order, the wonderful Rina Barth, Shira Ebbin & Zahava Marcus) a platform for listing furniture. It is called Freebee, and I would very much enjoy if you to check it out:

\n

The goal of Freebee

\n

Since Milestone 2 of the project, as a result of user feedback we have gotten, our team came up with a niche for Freebee: Try to make it the least hassle-worthy item sharing application around. A few features were direct results of this efficiency focus: A feature the course’s faculty very much liked, is that users of the app can store searches, and get push notifications (immediately from a server) upon a listing matching the query. Furthermore, upon adding a listing, a prominent button allowing artificial intelligence (served via Vercel AI Gateway, the model we are using is Claude 4.5 Haiku) which fills all fields for a listing based on a given photo. For each listing in the app there exists a queue, while only the top three can actually inquire about the product.

\n

Technical details

\n

The front-end of the app is written in TypeScript (utilizing React), while NextJS is used for the routing and light backend (full-stack is fun!). The website is linked up to Vercel Blobs (for listing photo storage) and to Neon Postgres (for the actual listings, accounts, queries). Authentication is done exclusively via passkeys (implemented using SimpleWebAuth) and messaging features are offloaded to WhatsApp (if a phone number is provided) or email (otherwise).

\n

Conclusion and observations regarding other people’s apps

\n

As mentioned in the preamble, this app was developed as a final project for the 47717 Web Application Development course at the Hebrew University’s MATAR (fmr. Internet & Society) program. The intoduction of artificial intelligence coding agents (such as Claude Code, OpenAI Codex) resulted in many of the students creating more feature complete apps than ever shown for this course. Fittingly, the course’s faculty have announced that future editions of the course will be adjusted to this “brave new world” of AI-assisted web development, by implementing what I think is a time-based requirement. Some noteworthy projects showcased at the course include an interview prep platform piggybacking off Leetcode, an infant clothing exchange, and an app for finding sabbath dinners (if you made any of these and want to be credited, let me know :D).

Here are a few screenshots of the app:

I finally got enough time and effort to develop some projects, which I will publish on this blog. Looking forward to post about them!
