Show HN: Any-LLM – lightweight and open-source router to access any LLM Provider We built any-llm because we needed a lightweight router for LLM providers with minimal overhead. Switching between models is just a string change : update "openai/gpt-4" to "anthropic/claude-3" and you're done. It uses official provider SDKs when available, which helps since providers handle their own compatibility updates. No proxy or gateway service needed either, so getting started is pretty straightforward - just pip install and import. Currently supports 20+ providers including OpenAI, Anthropic, Google, Mistral, and AWS Bedrock. Would love to hear what you think! https://ift.tt/HTy54vu July 23, 2025 at 12:40AM

Show HN: Create your color palettes in context, not isolation As a developer working with UI/UX teams, I’ve seen how much of a pain it still is to create accessible, well-balanced color palettes. A colleague of mine (UI/UX designer) mentioned how frustrating it is to: - Generate tints and shades from a brand color - Check WCAG accessibility contrast - Preview how those colors will actually look on buttons and components - Then jump between 2–3 tools just to get something usable So I built a tool to help fix that. 1. Choose a base color 2. Generate automatic tints/shades 3. Get WCAG contrast ratings live (against black/white backgrounds) 4. See automatically suggested complementary colors 5. And drop your palette directly onto real UI components (buttons for now, more coming) to visualise how your palette actually looks in a design system. You get to create your color palettes in context, not isolation Here’s the tool (free, no signup required to get started): https://ift.tt/NfemipG I...

Show HN: Communal Growth, find others with similar interests in books or papers Throughout my education and beyond, I always wanted to find buddies to study books and papers with. For various reasons, this has never materialized for me. Aside from academia, I've received a lot of help on IRC, and I'm aware that there's Reddit and Discord communities where people discuss Mathematics, Physics, and Computer Science (among other topics), but even there it is very hard to find people who wish to study together with you a specific article or book chapter. With Communal Growth, I'm hoping to zero in specifically on the interests of people down to the granular level of article and book titles. Are you (for example) interested in studying /New Directions in Cryptography/ by W. Diffie and M. E. Hellman? The process is simple: find the DOI (also: ISBN, arXiv) of the paper (e.g. with WorldCat) and send an e-mail to subscribe@communalgrowth.org with body doi:10.1109/TIT.1976.1055638...

Show HN: The missing link of a bookstore's tech stack Hi HN! I built Bookhead because I used to work as a bookseller and I wasn't happy with the software options when I decided to sell my own collection online (with the hopes of one day growing so I can open my own brick & mortar). So I decided to make my own bookselling app...a classic hacker distraction. Bookhead has two main parts: 1. an inventory management app that allows a bookseller to list their books anywhere they want to sell books (like Squarespace, Biblio, eBay, Shopify (coming soon!), etc) 2. an e-commerce platform with a CMS for selling books and letting a store control their online brand I have a very exciting roadmap that I'm not ready to fully reveal, but it's all based on books. I'm building a sorta Zapier-like platform for independent booksellers. Everything is so fragmented and disconnected, which makes it hard for booksellers to do their work. I'm hoping to change that. I have a blog pos...
