Hi Product Hunt! 😸 We're excited to officially peel back the curtain and say goodbye to the waitlist that we've had for ~2 years at Loops! In that time we have individually onboarded thousands of customers with thousands more still on the waitlist. We've taken all of that early feedback and learning...
We've been building Loops for the better part of the last two years. We haven't been building in silence either - the first year we did almost 300 onboarding calls. We have hundreds of Slack Connect channels set up with our users and it's helped us build this platform. We built Loops because we used...
Excited to hear what you all think!
Hi PH! I'm Zeno, founder of Resend. We're building a modern email sending platform focused on providing the best developer experience. Why? When you look at all the biggest competitors like Sendgrid, Mailgun, Postmark, and SparkPost, you'll notice that they were all founded around 2009/2010, and the...
Congrats on launching Resend! Tackling the issue of emails landing in spam is vital for developers. What specific features are you implementing to ensure high deliverability rates and real-time monitoring of email performance?
The UI truly looks sharp, well done!
Loops leads on raw interest score. Loops leads on engagement ratio. Loops leads on both metrics. That doesn't happen often.
These products share 2 categories: Developer Tools, Email. Moderate overlap suggests they target related but distinct use cases.
Loops is also tagged in Email Marketing, which Resend isn't. That suggests Loops positions itself more broadly or targets an adjacent audience.
Resend has unique category tags in API. Different positioning can mean a different buyer profile, even within the same space.
Loops launched Sep 2023. Resend launched Aug 2023. Both launched the same year, meaning they faced similar market conditions and competition levels.
Loops has a 0.19 engagement ratio (average), based on 299 discussion threads across 1,535 interest points. Middle of the pack for Email. Enough discussion to suggest real usage, but not the kind of buzz that indicates a category-defining product.
Resend has a 0.14 engagement ratio (below average), based on 183 discussions across 1,287 interest points. The low ratio suggests a launch that got attention but didn't convert that attention into sustained interest.
Within the Developer Tools category (5,444 total products), Loops ranks #2 and Resend ranks #4 by interest score. Loops sits in the top 10 for the category.
Loops is in the top 0% of Developer Tools by interest. Resend is in the top 0%.
Pick Loops if you want the product with the larger community behind it; sustained discussion and active users are your priority; you need something that also covers Email Marketing.
Pick Resend if community size matters less to you than engagement depth; you need something that also covers API.
Loops: Email for modern SaaS. Loops is a better way to send marketing + transactional email.
Resend: The best API to reach humans instead of spam folders. Build, test, and deliver transactional emails at scale.

Automatically. We compare products that share at least one category and have similar interest scores. Products too far apart in traction don't make for useful comparisons.
No. Interest is launch-day attention. Engagement ratio is a better quality signal. The product with more discussions per interest point usually has stronger product-market fit.
How directly these products compete. Three or more shared categories means they're going after the same user. One shared category means they approach the space from different angles. Zero overlap and they probably shouldn't be compared.
Comparisons are generated automatically when two products have enough data overlap. If the pair you want isn't here, the products might be in different categories or too far apart in engagement.
Either the product didn't meet our engagement threshold, or it doesn't share enough category tags with the other product to generate a meaningful comparison. We'd rather show no comparison than a misleading one.
Each product's data reflects its launch period. The comparison shows both products' engagement metrics from when they launched. The build date at the bottom of the page shows when the index was last refreshed.
