Permify was born out of our repeated struggles with authorization. Like any other piece of software, authorization starts small but as things grow scaling it becomes a real pain and begins to hinder product development processes. Ad-hoc authorization systems scattered throughout your app’s codebase are hard to manage, reason about, and iterate on as the company grows. Also you will need to have more specific access controls as things grow. Traditional approaches like RBAC is inefficient for defining granular permissions such as resource-specific, hierarchical, or context-aware permissions.…

Hey Everyone, Almost year ago we launched Permify an open-source authorization service to build fine-grained and scalable user permissions and access control systems over here(https://news.ycombinator.com/item?id=32096610) My co-founders and I had a enterprise solution agency where we worked with a bunch of fortune 500 companies. Each projects we made we have to re-invent the wheel for access control and authorization. Not having a easy to integrate, scalable and a granular system that can fulfill the requirements of these enterprise companies was a pain in the ass for us. As…

Hi folks, I’m one of the maintainers and co-founder of the Go OSS project Permify (https://github.com/Permify/permify), an open-source authorization infrastructure inspired by Google Zanzibar. I would like to share a post where we aimed to provide a brief overview of how we integrated WASM with Golang to provide a richer user experience in our open-source playground. You can use the playground to create and test any authorization logic in a browser. The playground has three main sections: Schema: to model your authorization logic through our domanin specific language we…

Hey HN, I recently shared my thoughts on why Google Zanzibar is a great solution for implementing authorization[1] and why we decided to build Warrant’s core authz service using key concepts from the Zanzibar paper. As I mentioned in the post, we recently open sourced the authz service powering our managed cloud service, Warrant Cloud[2], so I thought I’d share it with everyone here. Cheers!

Hi I'm Karan, one of the maintainers of Permify (https://github.com/Permify/permify), an open source authorization service to build scalable authorization systems. I want to share with you that we've built an AI assistant to help modeling your desired authorization logic! You can basically describe your authorization logic in Permify AI and it will generate the respective model and semantics accordingly. Think of it like ChatGPT for authorization modeling/policy generation. Here's the project if you would like to play with it: https://ai.permify.co/.…

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…

Hey HN, we're a YC startup building an open-source, privacy-first alternative to Perplexity Comet. No invite system unlike bunch of others – you can download it today from our website or GitHub: https://github.com/browseros-ai/BrowserOS --- Why bother building an alternative? We believe browsers will become the new operating systems, where we offload much bunch of our work to AI agents. But these agents will have access to all your sensitive data – emails, docs, on top of your browser history. Open-source, privacy-first alternatives need to exist. We're not a search or ad…

Over the past few months, we've been building Prism; a fast, developer-first observability UI that's deeply integrated with our open-source database, Parseable. Prism is designed for engineers who debug distributed systems, sometimes at odd hours, and need answers right now, without having to deal with five different tools. Backstory: We spoke to dozens of observability practitioners in large enterprises. Across the board, we heard two things: (1)The RoI on observability tools is hard to justify. (2)OSS leads to tool sprawl, metrics in Grafana, logs in ELK, traces… somewhere. We wanted a…
