Context.dev▲814Hello, 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.

Back in 2010 I had an idea for a service that would allow people to easily create semi-permanent email aliases so that they could give an email address to people and websites without revealing their real email address. These aliases will continue to work indefinitely unless you choose to block them. My brother and I spent a few months building the initial version and launched the website in July 2010. For the first year we had about 50 signups per month, by 2013 this had increased to 1500 and it's currently around 3500 per month. Similarly, our revenue grew consistently but slowly - doubling…

AhaSend▲132I'm the founder of AhaSend. We've built a transactional email service specifically for developers, with a Pay-As-You-Go pricing model ($0.50 per 1,000 emails) and up to 70% volume discount for platform partners. While there are many ESPs out there, we focused heavily on the Developer Experience to solve the pain of building and testing email flows: * The CLI: Heavily inspired by the Stripe CLI, we built a tool that lets you develop and debug locally. You can listen to webhooks, trigger events, manage your domains, and send / list / debug messages directly from your terminal. * True…

Hey HN, I'm Chris, CTO of Knock (https://knock.app). We built email.info because every developer we talk to asks the same question: which email provider should I use? The existing resources are mostly vibes — "Best of" listicles, anonymous Reddit threads, or LLM answers trained on that same content. Objective performance data is always missing. Knock is a notification infrastructure platform, so we send billions of API requests to downstream email providers every year. We aggregated that data into a public dashboard covering 10 providers (SendGrid, Postmark, Resend, Mailgun, Amazon…

Hi HN :) really excited to share this with you. The one thing AI reliably does is generate noise. Half the tools I see launch are just machines for producing more noise across more channels. And people are starting to see this in the form of emails in their inboxes as spam filters are struggling. There used to be a useful signal in email: the effort a sender put into customizing a message was a rough proxy for how relevant it actually was. AI killed that. Now it's customized slop with the appearance of effort with none of the cost. It is painful that the open internet / open channels…

Hey friends, I built a B2B email finder tool with waterfall enrichment. That means you can upload a list of prospects (name + company) and the tool searches through hunter.io, apollo, dropcontact and other email finder tools to find their email address. That way you can be sure the email is found (or cannot be found in a GDPR compliant way). Quick demo: https://youtu.be/K9efP0G3bR8?si=mWf7e0lZltRyJr80 Let me know your thoughts! :)
