Hosted version of Mathesar, intuitive open source UI built on Postgres
Hi HN! We just shipped the public beta of the hosted version of Mathesar, our open source “intuitive spreadsheet UI, full PostgreSQL power” project. Until now, using Mathesar meant installing and running it yourself. Now you can use Mathesar for free without having to maintain your own infrastructure at https://mathesar.cloud. Mathesar Cloud is run by the Mathesar maintainers through the 501(c)(3) nonprofit that already maintains the open source project. We’re committed to ALWAYS keeping Mathesar 100% open source (no open core), nonprofit, and treat self-hosting as a first-class…
What it does
In the maker’s words, at launch
Hi HN! We just shipped the public beta of the hosted version of Mathesar, our open source “intuitive spreadsheet UI, full PostgreSQL power” project. Until now, using Mathesar meant installing and running it yourself. Now you can use Mathesar for free without having to maintain your own infrastructure at https://mathesar.cloud. Mathesar Cloud is run by the Mathesar maintainers through the 501(c)(3) nonprofit that already maintains the open source project. We’re committed to ALWAYS keeping Mathesar 100% open source (no open core), nonprofit, and treat self-hosting as a first-class citizen. We’re launching a hosted service in part to sustain the project in the long term while keeping our principles. We’re also excited to be making Mathesar accessible to users who cannot or do not want to self-host. Currently, we have a free plan that’s great for solo projects, prototyping, and evaluating Mathesar for larger deployments. It’s scoped to a single database per user. We are using this early beta to learn what people need, as we work on launching more plans with feature parity with self-hosted Mathesar, including collaboration, control over Postgres roles and permissions, and connecting existing databases. I'd love your feedback on Mathesar in general, the Cloud version, or anything else! MORE ABOUT MATHESAR: Mathesar is a 100% open source project (we just got to 5000 stars!) that gives users a spreadsheet-like interface to PostgreSQL databases. You can connect an existing database or start a new one from scratch, it works the same either way. We aim for the UI to be familiar and intuitive for non-technical users while also using the full power of PostgreSQL without intermediate layers or abstractions. For example, our permissions system uses PostgreSQL roles and permissions directly.

Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
