About ProofSwap
ProofSwap is a free platform where indie developers exchange social proof — tweets, testimonials, video reviews, and app feedback — on a give-first model. You help another founder's project first, which activates your own listing, puts you in front of founders who can give you the proof you need, and earns you a permanent dofollow backlink from your indexed project page.
A give-first exchange engine for indie founders to trade visibility and help each other grow.
The key difference: you give first. Instead of posting a listing and waiting for someone to show up, you help another founder right away. That puts your listing live and gets you help in return. It's not an ad network or a marketplace — it's a community built on generosity.

How credits workFrequently Asked Questions
What is social proof exchange?
Social proof exchange is a practice where indie developers and founders trade visibility assets like tweets, testimonials, and video reviews. Instead of paying for ads or cold-emailing strangers, you help each other grow through fair, mutual exchanges. Read our complete guide or explore each exchange type.
Is ProofSwap free to use?
Yes, the core platform is completely free — creating accounts, submitting projects, and making exchanges costs nothing. Optional paid plans unlock instant activation, permanent listings, and a white-label embed widget. Check our pricing for details.
What does "give first" mean?
Instead of posting a listing and waiting, you start by helping someone else. Find a project that needs what you can offer and give them that proof. That single proof activates your own listing, and founders you help are shown your project first when they come looking for someone to help back. Start by finding a project to help.
Do I get a backlink for my project?
Yes. Every listing gets its own indexed project page that links to your site, and the link becomes dofollow once you've given proof to at least one other founder. It's earned by participating, never sold — that's what keeps it safe under Google's link spam rules — and because active givers are never delisted, it's permanent.
How are exchanges verified?
When you submit proof (like a URL to your tweet or written testimonial text), the receiver reviews and verifies it. Verified exchanges increase your trust signals and count toward your public exchange record, building your reputation on the platform. See real examples on the public Wall of Proof.
How do exchange credits work?
Every verified proof you give adds +1 credit to your balance. A credit pays for one additional project listing: your first listing is always free, and each one after that costs 1 credit plus an open project slot on your plan (Free 1, Starter 3, Pro 10, Business unlimited). Credits are never spent on receiving proof — proof you receive is free. If you are at your plan's project limit, your balance sits unused until a slot opens up. Browse projects to get started.
What types of social proof can I trade?
You can trade tweet/post shoutouts, written testimonials, video reviews, and app feedback. Each project specifies what it needs and what the owner can give in return. See all exchange types, browse projects needing testimonials, or read our blog for tips.
Is exchanging social proof ethical?
Yes, as long as exchanges are genuine and transparent. ProofSwap encourages honest endorsements between founders who have actually used each other's products. All exchanges should reflect real experiences. Our backlink safety guide and honest comparisons explain the difference between genuine reciprocity and schemes.
