Products that do what OpenInt (YC W23) Open-Source iPaaS to Ship Product Integrations Quickly does

Hi HN, we’re the team behind OpenInt (https://openint.dev). We started building a unified API for crypto payments at Map3 (YC W23), but scaling dozens of custom integrations for each customer was painful and repetitive. We learned how valuable it would be to have a platform that lets any team quickly stand up private and fully controlled integrations without reinventing the wheel each time. OpenInt is an open-source integration platform as a service (iPaaS) that helps you ship product integrations in hours, not weeks. We just participated Mega Launch Week (Dec 2–6…

    Hello HN! The day has finally come to stop adding features and start sharing what I've been building the last 5-6 months. It's a bit of CrewAI, OpenDevon, LangFuse/Cloud all in one, providing devs who prefer TypeScript an integrated framework thats provides a lot out of the box to start experimenting and building agents with. It started after peeking at the LangChain docs a few times and never liking the example code. I began experimenting with automating a simple Jira request from the engineering team to add an index to one of our Google Spanner databases (for context I'm the…

    We built Poozle (an open source platform) to simplify API integrations. Instead of dealing with multiple providers with different syntax and requirements, our platform offers a standardised interface through GraphQL. Why we built this: 1. In our previous jobs, we did many integrations and found no standardisation to the process. 2. Existing Unified API solutions lack customizability and only work for integrating multiple integrations from one vertical. Our beta version includes: 1. Plug n Play Integrations: Choose an integration from our pre-built list and start using it. 2. Playground:…

    We run superglue, an OSS agentic integration platform. Last week I talked to a founder of another YC startup. She found a use case for our CLI that we hadn't officially launched yet. Her problem: customers wanted to create Opps in Salesforce from inside the chat in her app. We kept seeing this pattern: teams build agents and their users can perfectly describe what they want: "pull these three objects from Salesforce and push to nCino when X condition is true", but translating that into a generalized hard-coded tool the agent can call is a lot of work and does not scale since the logic is…

    Founder here, Poozle integrates different APIs [Gmail, JIRA, Github, Salesforce, Pipedrive, Slack etc.] and provides a single GraphQL layer to integrate third party APIs and perform CRUD operations. In our previous jobs, we did many integrations, but we found that there is no standardization to the process. We had to write separate authentication code for each application, and for some applications, we had to integrate via APIs because the SDKs were stale. We also found that some integrations were completed quickly, while others took longer. Started working full time on this idea from Jan’23…

    Hi HN, I'm Dan Draper, founder of CipherStash. We've spent 5 years building per-value searchable encryption tech. We realized that encryption like this is incredibly powerful but the engineering required is generally not worth the effort. So we built a platform and opensource SDK to take the cry out of cryptography :) CipherStash Stack is: * A searchable encryption SDK for TS and Postgres * Fast, key management with Zerokms (backed by HSM) * A transparent SQL proxy * Auth library and OIDC federation service * Skills for data security Integrations include Prisma Next, Drizzle, Auth0, Clerk…

    Hey HN! We’re Alan and Richard from Integuru (YC W24). We generate fast, reliable integrations for platforms lacking official APIs. About 2 years ago, we released the first agent that reverse-engineers network traffic to build integrations (https://github.com/Integuru-AI/Integuru). Since then, we’ve developed a new approach to reverse-engineer platforms’ source code directly. This solution also includes authentication support. Here’s a demo: https://youtu.be/4l2L8fILC2g?si=nbWbDiFrWZIWRPM7. Many AI products need to integrate with web apps, but platforms…

    Hey HN, We built IPAware (https://ipaware.io) - an IP intelligence API that doesn't charge per request. What it does: - IP geolocation (country, region, city, coordinates, timezone) - Threat detection (VPN/Proxy/Tor, risk scoring, datacenter detection) - ASN/ISP data - Clean JSON responses Why we built this: Every IP lookup service we tried had the same problem - you start small, your app grow and suddenly you're paying hundreds for what should be a commodity lookup. The metering anxiety is real. We wanted something we could integrate without worrying about the bill…

    Hey HN, I’m building Databite, an open-source set of tools to help developers build integrations faster and with ease. If you’ve ever built a SaaS product or an AI agent that needed to update a CRM record, sync data between apps, or trigger a workflow in a third-party tool, you’ve probably spent way too much time writing glue code. Databite is here to be that glue. With Databite you can: - Access prebuilt connectors using the databite/connectors package. - Create custom connectors to services of your choice like Slack, Notion, HubSpot, Google Sheets, etc. using our databite/build…

    Hi HN! I just released assistant-tui, a terminal user interface for OpenAI's Assistant API. If terminal is your thing, it can be a great way to test and evaluate the API and its results. It implements not only the API, but also all the infrastructure to make it work, including polling, local repository, and more. Feedbacks and stars are welcome! https://github.com/dalssoft/assistant-tui
