Permanent webhook endpoints and instant HTTPS tunnels for developers and AI agents.
@BinaryScriptar · X
Introducing OtterKit. Always-on webhook endpoints and instant tunnels, built for developers and their AI agents. It started with a problem I kept hitting: every time my coding agent needed to test a Stripe or GitHub webhook, it had to open a tunnel. What OtterKit does • Permanent webhook URLs that answer senders 24/7 with the status, body and headers you choose, verify signatures on arrival (Stripe, GitHub, Shopify, Slack and 12 more), store full history, and forward matching events to your app, signed and retried • Instant HTTPS tunnels to any local port in one command, stable subdomains, auto stop, basic auth • Replay any captured request, edit the payload, re sign it, fire it at your local handler • Pulses: scheduled HTTP calls and dead man's switches with email alerts • Payload drift detection: baseline the JSON shape per event type, get emailed when a provider changes it • Custom domains ( and an email inbox on the same endpoint • A

Convert PDFs, Word docs, and more to clean Markdown for AI context windows.

Selling t0md.com – Privacy-first multi-format to Markdown converter A few months ago I was dumping research PDFs and Word docs into Claude and Cursor and watching the token bill climb for no good reason. Heavy formats are terrible for context windows as the agents have to first convert the documents, then parse the MD files, then do the processing. I thought I could help the agents, and I built t0md.com. However exciting it was to make something quickly that solves a big problem, it's not

Backend-as-a-service with MCP server, REST APIs, and row-level security for AI apps.

What we learned from trying to turn vibe-coded prototypes into production SaaS applications Founder here. While developing MCPBackend, we noticed a major difference between generating a convincing application demo and building a maintainable SaaS product. AI coding tools are increasingly capable of generating interfaces, routes and even initial application logic. But a production application still needs: a reliable data model authentication and authorization backend validation

Develop applications on Keeta blockchain through bounty tasks, SDK guides, and access to the developer registry.

So I got bored.. A few days ago I came across a site called One of the developer bounties it listed was for building a price oracle on Keeta. I included a screenshot of that bounty at the bottom of this post. I'm by no means a developer. I have a decent understanding of how this stuff works, but I've never built anything like this before. So I figured... why not give it a shot. I decided to use Claude Code to help me build it, and honestly I came away pretty impressed. It's crazy what you can build when you have a tool that can explain things, help troubleshoot, and let you iterate quickly. So I built a price oracle for Keeta. Why is that even needed? Anything running on-chain can't just call CoinGecko or an exchange API to ask for the current price. If a dApp, anchor, or smart contract wants to know what KTA, BTC, ETH, USDC, EURC, or another asset is worth, something has to fetch that information off-chain, determine the correct price, cryptographically sign i
