What it does
Shared, on-demand inboxes for testing the email your app sends — signups, resets, invites, magic links. Invent any address (or let AI spin up a whole roster), watch what each test persona receives with live team presence, and check off every expected email ✓ pass or ✗ missing — so the one that silently never arrives finally gets caught.
Spin up real inboxes at beta.cuevera.co and verify your app's email as a team — see what each persona received, who's checked it, and who's on it. Live.
Invent an address — it's a real inbox the moment your app sends to it. Your whole team watches the mail arrive, and signs off on what they see. Any name you can type is an inbox — no signup, no setup, nothing to create first. Every send shows up live for the whole team — who's seen it, who's checking what. No more "did you check this?" Mark each send pass, issue, or missing — then seal the verdicts into a permanent record. See something wrong? Draw a box right on the email. The box becomes a finding — the check, your note, the exact spot — and freezes into the sealed evidence. Nothing to annotate in another tool, no orphaned PNG in a thread. Each email carries its checks — logo renders,…from inbox.cuevera.co

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Homebrew 6.0.0▲1,481Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
