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!
Back in December 2023, our plane almost flew through an Icelandic volcano on the way to Cornell hackathon: we missed it by just days. Back then, we had no idea we were about to build something that would change how developers ship multilingual products. We were just two engineers tired of waiting we...
I really liked the new name of your product. From my experience of working on multilingual projects I can say that such project will definitely help teams to speed up idea->release cycle. This summer I want to spend some time on my pet projects, and lingo.dev is already in the list of my tools!
Lots of these translation systems we could use for our app (which has a global reach), but this one being open-source feels like the edge we needed to ensure our site's translations to every local language that we now serve is as naturally native as possible.
Resend leads on raw interest score. Lingo.dev leads on engagement ratio. That split is worth paying attention to. Resend attracted more initial eyeballs, but Lingo.dev's audience engaged deeper. For most buyers, engagement ratio is the better signal.
These products share 2 categories: API, Developer Tools. Moderate overlap suggests they target related but distinct use cases.
Resend is also tagged in Email, which Lingo.dev isn't. That suggests Resend positions itself more broadly or targets an adjacent audience.
Lingo.dev has unique category tags in SDK. Different positioning can mean a different buyer profile, even within the same space.
Resend launched Aug 2023. Lingo.dev launched Feb 2025. Resend has had more time to iterate and build a user base. Lingo.dev had the advantage of launching into a more defined market with clearer user expectations.
Resend has a 0.14 engagement ratio (below average), based on 183 discussion threads across 1,287 interest points. Low engagement relative to interest means the launch attracted clicks but not conversation. Could indicate the product appealed to a broad audience without hooking anyone deeply.
Lingo.dev has a 0.17 engagement ratio (average), based on 182 discussions across 1,058 interest points. Average engagement for the category. Solid but not exceptional.
Within the API category (888 total products), Resend ranks #1 and Lingo.dev ranks #2 by interest score. Resend sits in the top 10 for the category.
Resend is in the top 0% of API by interest. Lingo.dev is in the top 0%.
Pick Resend if you want the product with the larger community behind it; you value stability and a longer track record; you need something that also covers Email.
Pick Lingo.dev if community size matters less to you than engagement depth; sustained discussion and active users are your priority; you prefer newer tools with fresher tech; you need something that also covers SDK.
Resend: The best API to reach humans instead of spam folders. Build, test, and deliver transactional emails at scale.
Lingo.dev: Lingo.dev is an AI Localization Engine. It turns weeks of translation work into automated pull requests. Built by developers for developers, it produces authentic translations by understanding UI elements' placement and microcontext.

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.
Not yet. Current comparisons use launch-period data only. Post-launch tracking is on our roadmap.
Generally, yes. Engagement ratio is hard to fake. A product can generate artificial interest, but sustained discussion threads require people who actually used the product and had something to say about it.
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.
