Good Neighbor: Mutual-Aid Board
Community & Social Impact
Advanced
~3 hours

Somewhere along the way, neighborhood apps turned into surveillance feeds and complaint boards. You open one to borrow a ladder and instead get a thread about a suspicious van and someone's rage about parking. The actual neighborly stuff, lend a drill, share the extra soup, find a spare crib for the weekend, gets buried under noise and fear.
Real mutual aid is small, fast, and built on trust. It does not need another follower economy or another place to perform. It needs a board where asking for help feels safe and offering it takes seconds.
The brief: Design a local mutual-aid board where neighbors post small requests and offers of help, built so posting takes seconds and trust is visible without vanity metrics.
Who you're designing for
Marco, 41, just moved onto the block. He would happily lend his drill and would love to borrow a wheelbarrow this weekend, but he is done signing up for another social network that wants his attention and his outrage.
Constraints
Post a Need or an Offer in under 30 seconds, minimal required fields.
Two clear post types, Need and Offer, visually distinct at a single glance.
Trust without a follower economy: a verified-neighbor signal, no public like counts, no vanity metrics, no leaderboards.
Safe by default: approximate location only, never exact home addresses shown publicly.
Bonus round
Design a quiet "thank a neighbor" gesture that builds a person's reputation gently, without turning generosity into a scoreboard.
What good looks like
A brand-new neighbor can post a real need in 30 seconds.
The board feels safe and neighborly, not performative or fearful.
Offering help is as easy as asking for it, and trust is legible at a glance.
Suggested tools
Figma for the screens, Maze to test how fast a stranger can post, and pen and paper to sketch the Need-versus-Offer distinction before you build it.
Brand vibes
Olio for a generosity-first, share-what-you-have feel.
Buy Nothing for the hyperlocal gift-economy spirit and low-ego posting.
Nextdoor as the cautionary tale: study what turns a neighborhood app negative and surveillance-heavy, then design the opposite.
Felipe's tip
Community software should reward showing up, not showing off. This is a trust-and-safety problem as much as a UX one, and it rewards the empathy-first mindset in inclusive design and the incentive-shaping of behavioral design.
