onsubmit.dev

What it does

Onsubmit.dev is a simple and reliable form backend for static websites, JAMstack applications, landing pages, and frontend projects. It lets developers collect form submissions without building or maintaining a custom backend. Connect any HTML form to a dedicated endpoint and instantly receive submissions. Create notifications, trigger webhooks, integrate with email, Slack, Discord, and other services, and automate workflows while keeping your infrastructure lightweight, scalable, managable.

Accept form submissions from any website without writing backend code. Email, Telegram, Airtable, Notion, Google Sheets, and webhook notifications. Free tier, no credit card required.

Point action= at one endpoint and every submission fans out to your inbox, Slack, Notion — wherever your team already works. No servers, no config files. Enter your email to receive form notifications and manage submissions. onsubmit.dev replaces the backend you'd otherwise write to handle a form submission — no server, no database, no deploy. Here's the entire integration. Sign up with just an email and verify a 6-digit code — no password, no credit card. onsubmit.dev generates a unique POST endpoint for you the moment you land on this page. Set the endpoint as your form's action attribute, or POST to it with fetch. It works with a plain static HTML form, a React or Vue component, or a…from onsubmit.dev

  Hello, My name is Yahia, I've been working on scraping products for a long time and maintain a couple of free sites in my spare time (E.g. knifegeek.io) What prompted this is i've rebuilt scraping infra at every company I've started and finally just made it a product. Pass a URL, get clean markdown, html, images, sitemap or pass a domain, get logos, colors, socials, industry data. Goal is to offer a better service than VC funded competitors at a fraction of the cost. Stealth is included and automatic at no additional cost (normally an upcharge by alternatives). Would love your honest thoughts.

  Talanoa▲346

  Hi 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▲1,481

  Today, 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!
