Build a Slack Agent

Build a Slack agent in three API calls with durable agent sessions on OpenComputer. Define an agent, connect Slack, tag it in a channel — mentions start durable sessions, replies land in the thread.

StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 7 July 2026; the live site may have changed since.

Build a Slack Agent covers some of the launch checklist, with a thorough launch checklist, fast page loads, and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and no email security records.

Launched on Hacker News on July 7, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 2 days before launch. Our crawler found 13 technologies on this site, covering javascript library, security, analytics, and CDN. The stack includes Tailwind CSS, Cloudflare, and Cloudflare Bot Management.

It's also on one of the most common stacks we track, shared by 2,273 launches.
