Show HN: 1-Bit Pixel Art Font Editor I like making small fonts for Arduino and ESP32 projects with those little SSD1306 OLED screens. So I made this browser-based tool to help design pixel art fonts for use in those embedded projects.

It has a preview area that updates when you save your character. It can support fixed-width and variable-width fonts. And when you're done you can export the font in a few different formats.

It comes with a bunch of example fonts built-in. Also it's fully client-side code so you can save the webpage to use it offline.

If you want some inspiration for fonts, I made a bunch of really small fonts a few years ago: https://www.moonbench.xyz/projects/tiny-pixel-art-fonts/

Show HN: Widen – Open-source Mac Postgres GUI with local or cloud text-to-SQL Github: <a href="https:&#x2F;&#x2F;github.com&#x2F;betocmn&#x2F;widen" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;betocmn&#x2F;widen</a><p>I was paying for DataGrip for several years as my desktop database GUI but if I wanted text-to-SQL with LLMs I&#x27;d have to pay even more on top. So I decided to build my own and I&#x27;ve been using it for a few weeks now.<p>At any time I&#x27;m usually working with 3 to 6 databases, and having them set up in something like Conductor (for parallel agentic coding), but for Postgres databases, lets me quickly start a session, ask questions to my database in plain English, get a data export, move on and close the session. It&#x27;s been working well and I thought I would share it here.<p>It&#x27;s a native Mac app (Swift), free and open source (MIT). For the LLM you bring your own OpenRouter key, or there&#x27;s an experimental on-device mode using Apple&#x27;s local model, where nothing leaves your Mac. Cloud mode only sends the question and schema metadata, not your data, unless you explicitly turn that on per connection.
