Outpost – OSS infra for outbound webhooks and event destinations
Hey HN, we're launching Outpost, an open-source, self-hostable component designed to handle outbound event delivery for SaaS/API platforms. If you're building a platform, you eventually need to send events to your users (think payment success, resource updates, workflow changes). Implementing this reliably—handling retries, monitoring, scaling, providing a decent dev experience for consumers, and managing tenants—becomes a significant, recurring engineering task that distracts from core product development. We built Outpost to offload that complexity. Outpost delivers events via…
Outpost – OSS infra for outbound webhooks and event destinations launched on May 6, 2025 with 67 votes, #588 of 7,905 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
Outpost is an open-source, self-hostable infrastructure component for SaaS and API platforms to deliver outbound events to users. It handles webhooks and direct event destination delivery to message queues and buses, managing retries, monitoring, scaling, and multi-tenant operations. Designed for platform builders, Outpost reduces engineering overhead by centralizing event delivery reliability and developer experience, allowing teams to focus on core product features rather than building delivery infrastructure from scratch.

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…

Tapflow 2.0▲1,125We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
