Tines ▲557Hey HN! This is Yannick from Tines, really excited to share what we’re launching today. Tines 3B is a new product we’ve built for teams building agents, apps, and automations with AI, on top of the assumption that people are already doing this, whether or not IT or security knows about it. Finance, marketing, and more are building dashboards in Claude Code or Codex. None of it is malicious, people are doing exactly what they were asked to do. The issue is there's no easy way for that work to run securely: it ends up on a laptop or personal account, with a credential pasted directly into the…

The task came with a sense of helplessness. We knew what "great" looked like, but it was impractical to build all of that functionality.

Kelviq▲530Hi HN, We've been building Kelviq for the last couple of months and it's finally ready to share. Kelviq is a Merchant of Record (MoR) and monetization platform that you can integrate without building a custom webhook-to-database syncing layer. Along with handling global taxes, checkout, and compliance, it acts as the real-time source of truth for your users feature access and usage credit balances. Why we built this: Through our other project, ParityDeals, we saw firsthand how much founders struggle with billing infrastructure. Integrating a payment gateway is easy, but actually building…

Hey HN! Happy to finally launch Stack. We made it because we like to put apps into production quickly, and authentication & user management was taking up way too much time. We have components like and that automatically adapt to whatever theme & design system you're using. Check the blog post to see the example with Radix UI and Joy UI. Also, there's an admin dashboard for monitoring and editing accounts. Stack is 100% AGPL/MIT-licensed, so you can self-host it. Cheers!

Hi HN! I’m Arash, one of the founders of Strada (https://www.getstrada.com), a cloud IDE for building automation workflows across your company’s SaaS apps. Strada handles integrations, triggers, infrastructure and observability while letting you write core workflow logic in Python (more languages soon). It's for teams that hit limitations with low-code tools while building with internal apps — eg. Zendesk, Jira, Salesforce, Slack. You can access our docs at (https://docs.getstrada.com). While working on our first product (a unified accounting API), we learned that as…

Hey HN, Nir, Gal and Tomer here. Last week, we open-sourced Enrolla (https://github.com/enrolla/enrolla) - feature management for SaaS companies. It makes it easy for developers to control how their product behaves for customers in different pricing tiers. So things like which features are enabled for whom, rate limits and seat limits, but also your customer secrets (with end-to-end encryption), and other configurations. After 15 years of working together at various companies, where we rebuilt the same SaaS foundation layer again and again - we wanted to create something…

Hi everyone, We’re building an open-source identity and risk management platform and we’ve just released the first chunk of code, a fully customizable KYC flow & UI, to the public. We’ve chosen to use Svelte so our flows would be lightweight (it is ~50kb gzipped). Next up: - Adding forms and components for it to be used as a full onboarding flow. - Releasing an open-source case management dashboard, for manual approval of users. - Releasing an open-source rule engine, to help automate decisions. We’d love to hear your feedback, suggestions, or any question you’ve got. And if the rest of the…

Hi folks! I'm Ulysse, and Tesseral (https://github.com/tesseral-labs/tesseral) is open-source auth for B2B SaaS. Early in my career, I worked on enterprise auth and security features at Segment. I've been obsessed with the subtle details of enterprise software ever since. For example, I wrote an implementation of SAML in the early days of the COVID pandemic because I thought it was fun. Over the years, I've felt frustrated that too few people have seemed interested in making auth obvious for developers of business software. Auth really doesn't need to be so confusing. We…
