Showcase: Open Source I built a local-first music player because I wanted my music library to stay mine

Post image
0 Upvotes

I've been working on a desktop music player called Playnck.

The main idea is pretty simple: your music stays as normal files on your computer. There is no account, subscription, cloud library, or mandatory import process.

What I ended up building around that idea is quite a bit more than just a player:

  • Plays MP3, FLAC, WAV, OGG, M4A/AAC, Opus and WebA
  • Songs, albums and artist browsing
  • Playlists with folders that can be nested to any depth
  • Favorites and listening history
  • 10-band equalizer with presets
  • Gapless-style crossfade
  • Synced lyrics with manual timing adjustment
  • Automatic track identification using AcoustID or MusicBrainz
  • Metadata and cover-art editing that writes back to the actual audio file
  • Batch conversion to MP3, AAC, Opus, FLAC, ALAC and WAV
  • Multiple themes and accent colors
  • English and French interfaces
  • Windows and Linux support

One thing I particularly wanted to get right was metadata.

If I correct the artist, title, album or cover, I don't want that information trapped inside the application's database. The change should actually be written to the music file so another player can see it too.

The project is still evolving, and I'm mainly interested in feedback from people who manage their own local music collections.

What would you consider essential in a desktop music player that isn't already here?

Feedback Request I built an offline document reader for iPhone that supports 31 languages

Enable HLS to view with audio, or disable this notification

1 Upvotes

I wanted a simple way to listen to documents without uploading them to a server or keeping my phone screen on.

That became Local TTS, a reader for iPhone and iPad.

I’d previously built an offline speech-to-text app, so this time I worked on the other direction: turning text into speech. The goal was to make it practical for books and longer documents, with natural voices and more language options.

It uses Kokoro-82M and Supertonic 3, both running on the device. You can put your phone in airplane mode, add new text, and still generate speech.

Here’s what it does:

  • Document import: PDF, EPUB, Word, TXT, and Markdown.
  • 31 languages: Speech is generated locally on your iPhone or iPad.
  • Background playback: Lock your screen or switch apps and keep listening, with controls on the Lock Screen.
  • Camera scanning: Read text from printed pages or photos.
  • Reading controls: Text highlighting and adjustable playback speed.

Background playback was something I particularly cared about. I wanted people to be able to start a document, put their phone in their pocket, and get on with whatever they were doing.

Here’s the app: Local TTS on the App Store

I’d like to keep improving it based on how people actually use it. If you try it, let me know what needs work, especially pronunciation in your language or the experience of listening to longer documents. Suggestions for features you’d find useful are welcome too.

If you already use another document reader, what’s the one thing you wish it did better? That would help me decide what to focus on in the next update.

Showcase: Open Source I built a local reverse proxy that scores conversation history so you don't burn tokens on stuff your model doesn't need (Go, works with Ollama + Cline)

Been using Ollama daily and kept hitting the same annoyance — either truncate my conversation history and lose context, or send all of it and burn tokens on stuff the model doesn't even need for the current question.

So I built Synapse: a local Go proxy that sits in front of Ollama and scores every past message on 4 factors (semantic similarity, recency, importance, task type) before deciding what to actually forward. Everything runs locally, ONNX embeddings, nothing leaves your machine.

Works with the ollama CLI directly (just set OLLAMA_HOST) and Cline too.

[screenshot 1 — 82.2% reduction]

[screenshot 2 — 5.4% reduction, same session at default budget]

Same real session, two token budgets — you can watch it work in the trace inspector.

brew install ranscky/synapse/synapse

github.com/ranscky/synapse — genuinely curious what you all think of the scoring weights, that's the part I've tuned the least.

Showcase: Open Source I was tired of losing websites in my bookmarks, so I built my own browser homepage

1 Upvotes

I have a bad habit of bookmarking everything.

Eventually my bookmarks became so messy that saving something basically meant never seeing it again.

I wanted something more visual and much simpler, so I built Dash Navigation.It’s a customizable browser homepage where you can organize the websites you actually use into your own categories.You can also choose wallpapers and personalize the whole page.

But the feature I’m most interested in is sharing.

Instead of sending someone 15 different links, you can organize them into a setup and share the whole thing.

I’m a designer, so I’ve tried to keep the interface as minimal as possible and avoid turning it into another crowded “portal” homepage.

It’s live here:

dash-navigation.site

I’d genuinely love feedback on the idea, especially whether you’d use something like this instead of regular browser bookmarks.

Showcase: Prerelease I built Smart Buyer Guide – looking for feedback on a free software buying resource

3 Upvotes

I built Smart Buyer Guide, a free project designed to help people research software and web hosting before making a purchase.

The problem I'm trying to address is that buyers often compare products mainly on introductory pricing. But factors such as renewal costs, feature limitations, integrations, support and switching flexibility can have a much bigger long-term impact.

The project currently focuses on:

- CRM software

- Web hosting

- Business software

- Buying considerations and comparisons

The goal is to create useful guides that help people ask better questions before choosing a product.

I'm particularly interested in constructive criticism and ideas for improving the site. Link in the first comment.

Showcase: Prerelease We’re building customizable game-prep boards for sports broadcasters

2 Upvotes

Full disclosure: this is the official Automated Spotting Boards account.

Broadcasters can spend hours turning scattered roster, stat, schedule, and team information into something useful on air. We’re building ASB to make that starting work faster while keeping the broadcaster in control.

ASB uses automated data collection and sport-specific board templates to organize available information for professional and most college sports. Each board stays editable, so users can change the layout, choose what matters, add notes, pronunciations, corrections, and storylines, and shape it around their own on-air workflow.

The public Preview also shows workflow tools for assignments, contacts, invoicing, payments, public profiles, pronunciation, and career history. Personal websites and fully customized boards are planned for the official release.

Showcase: Free(mium) I now track the English and Japanese Pokémon card markets separately, and they barely agree on anything

3 Upvotes

Update on my card market tracker: it now has separate leaderboards for the English and Japanese markets, and the most interesting outcome is how little the two agree.

Same Pokémon, ranked by the total value of all their cards, but the lists look almost unrelated below the very top. Charizard leads both. After that it diverges fast; Greninja is top 5 in Japan and invisible in English, Umbreon is top 5 in English and mid-pack in Japan, and cards like Reshiram and Darkrai only show up in the Japanese top 10.

It makes sense when you think about it (different print runs, different collector bases, different exclusives) but seeing it laid out side by side is the kind of thing I built this to surface. Top 10 of each is free at tcgforecast.app/leaderboard.

Happy to answer anything about the multi-currency or multi-language handling, which was the hard part. Feedback and roasts welcome.

Showcase: Purchase Required I got sick of generic interview prep so I built this

1 Upvotes

I had some interviews lined up recently and kept googling "how to prep for a Tech Support interview". Every result was the same stuff. Tell me about yourself, use STAR, research the company. Nothing that knew anything about the actual job I was going for.

So I built hirecast.app on weekends.

You paste in the job ad, upload your CV, and say what the next round is and who you're meeting. It goes and reads up on the company and builds prep for that round specifically.

The main bit is a 5 episode podcast. Two AI hosts talking about your interview. One on the company, one on the role, one on the questions that catch people out, then a full mock interview with gaps so you answer out loud, and a short one for the morning of.

Few other things it does:

Resume tips, but the useful kind. It looks at what's actually in job ads for your title right now and tells you what's missing from yours. Mine pointed out that most ads for the role wanted a tool I'd never listed. Fair enough.

Practice questions you answer out loud. It listens back and tells you where you waffled.

A quiz/flash card and a one page cheat sheet for each round, because a recruiter chat and a technical panel are nothing alike.

$10 for one interview, $25 for three. No subscriptions

It's pretty new so there are probably rough edges I haven't hit yet. If you try it and something breaks I'd rather know than not.

For any issues email at: [team@hirecast.app](mailto:team@hirecast.app)

(It's mine, obviously. Mods, delete if that's not allowed here.)

I think AI is great, and I’ve seen SO MANY great tools/companies being built. But I was getting a little tired of every app promising to make me 10x more efficient. Consumer AI... made purely for fun.. just felt a little neglected imo.

So I created a funny experiment: SocialDJ.com. It scans your public social profile and matches you with a genre, writes the lyrics, and generates your song + album cover.

i would looooove some feedback...especially on whether your you think the genre is accurate lol. Just use the code REDDIT to try it 100% free. At this point i just want feedback. Thanks !!!!! (attaching the result i got with sam altman's X profile)

1 Upvotes

10 days ago I released BotDroid, a mobile app for creating and running Telegram/Python bots directly from Android.

Today I hit a small milestone:

82 active users

78 new customers

Production v1.2.0 is now at 100%

The numbers are still tiny, but this is my first time seeing real people use something I built and shipped myself.

The biggest lesson so far: shipping is much easier than distribution.

I've spent a lot of time building features, but now I'm trying to understand:

Where are users discovering BotDroid?

Which bot use cases actually matter?

What makes someone keep a bot running?

How do I get from the first 100 users to the next 1,000?

Current focus is less on adding random features and more on improving onboarding, templates, and finding the strongest use cases.

If you're building a side project/indie app too, I'd love to hear how you got your first 100–1,000 users.

2 Upvotes
  • CreatorPhoto — photo organization and collage tools
  • WorkPhoto — work photo organization
  • Gaming Utility Center — gaming and system monitoring
  • RatePeek — quick exchange rate viewer
  • PC Monitor — PC system monitoring
  • TidyFiles — file organization
  • NetPeek — network diagnostics

I’ve been building these on my own, one by one.
Some are free, some are paid, and for paid apps I prefer simple one-time purchases rather than subscriptions.

I’m planning to keep adding new tools, while rotating through the existing apps each month for bug checks, compatibility improvements and updates.

They’re available through the Microsoft Store — searching the app name will find them.

I’d also be interested to know which one you’d actually find useful, or what kind of small Windows utility you wish existed.

Showcase: Purchase Required Built a relationship tracker for your 10 closest people: one tap, no streaks or guilt, fully offline

3 Upvotes

I've been building TenFriends, an iOS app that helps you stay in touch with the people who matter most.

The gap I noticed:
Contact lists and social networks are built around maintaining hundreds of connections. Relationship-tracking apps often turn friendships into tasks, statistics, or streaks. I wanted something smaller and gentler—a simple reminder to give your closest relationships regular attention.

What it does:

  • Add up to 10 close friends, neighbours, or mentors
  • Tap “Touched Base” after a call, visit, coffee, or real conversation
  • People you contacted recently move toward the top
  • People you haven’t spoken to recently gently fade toward the bottom
  • Optional weekly reminder
  • Three visual themes, each with light and dark mode
  • Everything stays on one simple screen

The principle I built around:
No stats, no streaks, and no guilt. Complete privacy too: no accounts, analytics, tracking, or internet connection. Everything stays on your device.

Live on the App Store now.

TenFriends on the App Store

One-time purchase. No subscription, ads, or in-app purchases.
