Show HN: Davia – A community platform to build, share, and edit applications
Hi HN!<p>I'm Ruben, the founder of Davia (<a href="https://davia.ai/" rel="nofollow">https://davia.ai/</a>). Davia is a platform to build, edit and share applications, where builders get rewarded based on usage while users can discover and reuse any app's code to fit their own needs.<p>The problem we're trying to solve: Today's AI coding platforms charge you upfront for creation - it's like paying per block modification in no-code solutions. This works for commercial projects because you're aiming to generate revenue that exceeds your creation costs, but doesn't fit the reality of side projects and community apps that builders share for free. Most side projects require significant SEO effort and marketing to reach people who would actually find them useful, leaving creators with great apps but no discoverability.
For users, when you need a specific tool for your project, you don't want to build it from scratch when someone has probably already created something similar.<p>Our solution is a YouTube-style platform for apps where builders publish with open code so anyone can view, modify, and reuse applications. Unlike traditional platforms like GitHub (designed for developers as builders and users) or app stores (where code is closed and can't be modified), we focus on making apps accessible and customizable for everyone.<p>We verify code quality and prevent spam to maintain platform standards. Builders get rewarded when their original apps are used as foundations for others' projects. Users discover apps, customize them for their needs, and build their own versions through reuse. They can either self-host or use our platform hosting, paying based on team usage when they scale to multiple users on our infrastructure.<p>You can try it here: <a href="https://davia.ai/" rel="nofollow">https://davia.ai/</a>. We'd love to hear from the HN community, whether you're a vibe-coder or curious about creator economics in the age of AI-assisted development!

Show HN: Blueprint: Fast, Nunjucks-like templating engine for Java 8 and beyond
I love the simplicity, expressibility and extendibility of Nunjucks.<p>But I was not able to find something with similar for Java, especially with the same syntax.<p>So, built one. And it's pretty fast too.<p><a href="https://github.com/freakynit/Blueprint" rel="nofollow">https://github.com/freakynit/Blueprint</a>
Show HN: Fine-tuned Llama 3.2 3B to match 70B models for local transcripts
I wrote a small local tool to transcribe audio notes (Whisper/Parakeet). Code: <a href="https://github.com/bilawalriaz/lazy-notes" rel="nofollow">https://github.com/bilawalriaz/lazy-notes</a><p>I wanted to process raw transcripts locally without OpenRouter. Llama 3.2 3B with a prompt was decent but incomplete, so I tried SFT.
I fine-tuned Llama 3.2 3B to clean/analyze dictation and emit structured JSON (title, tags, entities, dates, actions).<p>Data: 13 real memos → Kimi K2 gold JSON → ~40k synthetic + gold; keys canonicalized. Chutes.ai (5k req/day).<p>Training: RTX 4090 24GB, ~4h, LoRA (r=128, α=128, dropout=0.05), max seq 2048, bs=16, lr=5e-5, cosine, Unsloth. On 2070 Super 8GB it was ~8h.<p>Inference: merged to GGUF, Q4_K_M (llama.cpp), runs in LM Studio.<p>Evals (100-sample, scored by GLM 4.5 FP8): overall 5.35 (base 3B) → 8.55 (fine-tuned); completeness 4.12 → 7.62; factual 5.24 → 8.57.<p>Head-to-head (10 samples): ~8.40 vs Hermes-70B 8.18, Mistral-Small-24B 7.90, Gemma-3-12B 7.76, Qwen3-14B 7.62. Teacher Kimi K2 ~8.82.<p>Why: task specialization + JSON canonicalization reduces variance; the model learns the exact structure/fields.<p>Lessons: train on completions only; synthetic is fine for narrow tasks; Llama is straightforward to train.

Show HN: My first Go project, a useless animated bunny sign for your terminal
Hi HN, I wanted to share my very first (insignificant) project written in Go: a little CLI tool that displays messages with an animated bunny holding a sign.<p>I wanted to learn Go and needed a small, fun project to get my hands dirty with the language and the process of building and distributing a CLI. I've built a similar tool in JavaScript before so I thought porting it would be a great learning exercise.<p>This was a dive into Go's basics for me, from package structure and CLI flag parsing to building binaries for different platforms (never did that on my JS projects).<p>I'm starting to understand why Go is so praised: it's standard library is huge compared with other languages. One thing that really impressed me was the idea (at some point of this journey) to develop a functionality by myself (where in the javascript original project I choose to use an external library), here with the opportunities that std lib was giving me I thought "why don't try to create the function by miself?" and it worked! In the Js version I used the nodejs "log-update", here I write a dedicated pkg.<p>I know it's a bit silly, but I could see it being used to add some fun to build scripts or idk highlight important log messages, or just make a colleague smile. It's easy to install if you have Go set up:<p><pre><code> go install github.com/fsgreco/go-bunny-sign/cmd/bunnysign@latest
</code></pre>
Since I'm new to Go, I would genuinely appreciate any feedback on the code, project structure, or Go best practices. The README also lists my planned next steps, like adding tests and setting up CI better.<p>Thanks for taking a look!

Show HN: Woomarks, transfer your Pocket links to this app or self-host it
Pocket is shutting down and I really, really liked it. So I built woomarks, an app that let's you save links with a similar UI. It's very minimal, but it's doing everything I liked from Pocket and you can bulk import your links and use the app or self-host.<p>- Public app that you can test: <a href="https://woomarks.com/" rel="nofollow">https://woomarks.com/</a><p>- My self-hosted version, where you can see my saves: <a href="https://roberto.fyi/bookmarks/" rel="nofollow">https://roberto.fyi/bookmarks/</a><p>- Repository if you want to self-host: <a href="https://github.com/earlyriser/woomarks" rel="nofollow">https://github.com/earlyriser/woomarks</a><p>Export links from Pocket here: <a href="https://getpocket.com/export" rel="nofollow">https://getpocket.com/export</a> the last day will be on October 20025.<p>Features:
- Add/Delete links
- Search
- Tags
- Bookmarklet (useful for a 2-click-save)
- Data reads from:
csv file in server (these links are public)
local storage in browser (these links are visible just for the user)
- Local storage saving.
- Import to local storage from csv file
- Export to csv from local storage.
- Export to csv from csv file (useful when links are "deleted" using the app and just hidden using a local storage blacklist).
- Export to csv from both places.
- No external libraries.
- Vanilla css code.
- Vanilla js code.
Show HN: Moribito – A TUI for LDAP Viewing/Queries
Check out my TUI I wrote for viewing and querying an LDAP. I need to do basic queries and validation daily for work, and as I work on a mac, there are really no good options. The major player is the Apache Directory Studio which is... not great. So I decided to create a new one.

Show HN: Amber – better Beeper, a modern all-in-one messenger
Hi HN! Excited to share early access to Amber.<p>I’ve tried every all-in-one messenger out there (Beeper included) but they always fell short. No real folders, no AI, clunky UI, no CRM features… As a founder who speaks with hundreds of people every quarter, I needed something better. So I decided to rebuild the entire experience from ground up.<p>Thoughts from one of our users: "The app I've been searching for for a looong time."<p>Check it out for free today!<p>Demo:
<a href="https://www.loom.com/share/8b5bc80b9893436b9190ae41fc3f0f50" rel="nofollow">https://www.loom.com/share/8b5bc80b9893436b9190ae41fc3f0f50</a><p>Features:
- All messages (Whatsapp, Telegram, iMessage) unified in a beautifully crafted interface.
- Split inboxes (folders) to effortlessly focus on work, friends, a particular project.. whatever matters the most right now.
- Mark read – no read receipts (even on Whatsapp and Telegram), mark done only when you’re done.
- Personal CRM: a lightweight private database of knowledge about each person with (optional) AI pulling important facts straight from conversations. (the latter is coming soon)
- Command bar + shortcuts.
- Send later + reminders.<p>Everything is securely stored on-device. All messages are end-to-end encrypted and go straight from your device to the network of choice – never touching our servers.
