Business Ideas From r/selfhosted

“I've tried everything from Nextcloud, ownCloud, OpenCloud, and Pydio Cells. But I still can't seem to find exactly what I'm looking for, and I'm wondering why it doesn't already exist. File storage is (in my opinion) one of the most helpful use cases for a self-hosting setup, but I don't understand why there isn't a self hosted cloud storage platform that: - is cross-platform - has relatively low resource usage - uses a flat file structure, not S3-style blobs - handles thumbnailing for more file types than just images - has virtual filesystems OR selective sync for common operating systems - has decent sharing or multi-user tools - has good upload and download speeds Essentially, I don't understand why a fully self-hostable and user-friendly Google Drive alternative doesn't exist. I'm a developer and I understand that it would obviously be a large undertaking to build, but it's a type of software that's very common for self-hosters and I don't see why a better option doesn't exist”

No simple free self-hosted file storage exists despite trying Nextcloud etc.; strong underserved need for easy Dropbox-like self-host

“Curious what people think as we head into 2026. Even with how far self-hosting has come, what apps or services do you still think aren’t realistically self-hostable, or only have “good enough” alternatives? For me it’s Google Maps / Waze — real-time traffic, routing, incidents, POIs… I haven’t found anything self-hosted that comes close overall. I *can* self-host email, but honestly prefer not to. And for things like WhatsApp / Facebook / Instagram, the network effect makes self-hosting basically impossible for my family and friends. What’s yours? What do you still rely on SaaS for, even as a self-hoster?”

Google Maps/Waze can't be self-hosted well; real-time traffic/routing is expensive unsolved vertical

“Hi everyone, I'm looking for a self-hosted documentation solution for my homelab. I’ve looked at options like Wiki.js and Docmost, but I’m not fully convinced yet. What I’m trying to build is more than just basic documentation — I want a central knowledge base for my setup: - What services are running where? - How did I install/deploy things (e.g. Docker, Ansible, etc.)? - Why did I make certain decisions? - How are components connected (networks, dependencies, etc.)? The goal is to have something I can revisit months later and still understand what I built and how to reproduce it. Nice to have: - solid structure (tags, categories, etc.) - API or automation options (e.g. integration with Ansible or similar tools) - low maintenance overhead Any recommendations or real-world setups that have worked well for you? I’d also appreciate examples of how you organize your documentation. Thanks! ”

“Hey everyone, I’m looking for a tool that would help me monitor database backups. Specifically, I want to keep an eye on automated backups for MongoDB and MySQL. It would be great if the tool also provided a web interface for managing configuration and viewing backup status. Right now I'm relying on crontab, but it's not very convenient, if something fails, it often fails silently, and setting up proper alerting is a bit painful. I hate creating too complex scripts to do stuff, because I easily forget how they work and where they are configured. I'm not necessarily looking for a single tool that does everything for me. I'm open to a combination of two or more tools, one for running backups or scripts (like cron) and another for monitoring and/or alerting, if that would give me the same functionality. Any recommendations or setups you've had good experience with? /Edit: I know people here hate Raspberry Pi, but before you say "don't back up on microSD", I'm using a Raspberry Pi”

Teams running automated DB backups need a dedicated monitoring tool with web UI for status, config and failure alerts

“Today, after raising security concerns in a post on r/huntarr regarding the lack of development standards in what looks like a 100% vibe-coded project, I was banned. This made my spidey senses tingle, so I decided to do a security review of the codebase. What I found was... not good. TLDR: If you have Huntarr exposed on your stack, anyone can pull your API keys for Sonarr, Radarr, Prowlarr, and every other connected app without logging in, gaining full control over your media stack. # The process I did a security review of Huntarr.io (v9.4.2) and found critical auth bypass vulnerabilities. I'm posting this here because Huntarr sits on top of (and is now trying to replace them as well!) Sonarr, Radarr, Prowlarr, and other *arr apps that have years of security hardening behind them. If you install Huntarr, you're adding an app with zero authentication on its most sensitive endpoints, and that punches a hole through whatever network security you've set up for the rest of your stack. **”

“We've all seen the big news: Discord is introducing facial ID as a requirement to actually use the app starting next month. Which means one thing: people are about to dig through dozens of ancient "what's the best self-hosted Discord alternative?" threads on here and find antiquated opinions and advice. What are we *actually* using? What are the clients that work well? What are options that pass the "wife test" of actually being something you could convince your not-techy friends and family to install on their phones? Let's get into it. I know I'm already anticipating self-hosting *something* to replace Discord for communities/friend groups who'll naturally slough off when face ID comes along.”

Demand for self-hosted Discord replacement due to new facial ID requirement; clear tool shortcomings

“Hey r/selfhosted! I have 2TB+ of personal video footage accumulated over the years (mostly outdoor GoPro footage). Finding specific moments was nearly impossible – imagine trying to search through thousands of videos for "that scene where "@ilias' was riding a bike and laughing." I tried Google's Video Intelligence API. It worked perfectly... until I got the bill: about **$450+ for just a few videos**. Scaling to my entire library would cost **$1,500+**, plus I'd have to upload all my raw personal footage to their cloud. and here's the bill https://preview.redd.it/lzejfn9i3gxf1.png?width=607&format=png&auto=webp&s=30420ba1b4402f8bf791347165d2ac973d5fb39a So I built **Edit Mind** – a completely self-hosted video analysis tool that runs entirely on your own hardware. # What it does: * **Indexes videos locally**: Transcribes audio, detects objects (YOLOv8), recognizes faces, analyzes emotions * **Semantic search**: Type "scenes where u/John is happy near a campfire" and”

“Alright discord wants my government ID now, that’s fun and cool. So what self hosted options are there that have a similar feature set? Multiple voice channels, text channels, media sharing. Nextcloud comes to mind but that’s overkill. I know teamspeak is popular but it’s only voice. Anything exist out there people like?”

“I've been working on a note taking app called Anchor and wanted to share it here. There are already plenty of self hosted awesome note taking apps out here, but I couldn't find what I actually needed, a proper Google Keep replacement that's mobile first, really easy to use, and works offline. I write most of my notes on my phone while I'm out, so I needed something that works smoothly on mobile, not just a web app that happens to work on phones. Everything needs to work offline too, since I'm sometimes writing things down when I don't have a connection. That's why I started building Anchor. It's designed mobile first, so the interface is simple and fast on your phone. All your notes are stored locally, so you can edit them anywhere, anytime, even without internet. When you do get online, everything syncs automatically across your devices. There's a web app too, so you can access and organize your notes from any browser. The mobile app is available for Android right now in the Github”

“I got tired of relying on clunky SaaS tools for meeting transcriptions that didn’t respect my privacy or workflow. Everyone I tried had issues: * Bots awkwardly join meetings and announce themselves. * Poor transcription quality. * No flexibility to tweak things to fit *my* setup. So I built **Amurex**, a self-hosted solution that actually works: * Records meetings quietly, with no bots interrupting. * Delivers clean, accurate transcripts right after the meeting. * Automatically drafts follow-up emails I can edit and send. * Keeps a memory of past meetings for easy context retrieval. But most importantly, it has it is the only chrome extension in the world that can give * Real-time suggestions to stay engaged in boring meetings. It’s completely open source and designed for self-hosting, so you control your data and your workflow. No subscriptions, and no vendor lock-in. I would love to know what you all think of it. It only works on Google Meet for now but I will be scaling it t”

“I know this question gets asked every couple of months, but I'm having a hard time deciding what to use instead of Linkding. I've been really happy with Linkding over the past few months, but it doesn't support multiple word tags (i.e. "Reddit Posts" etc.), so I'm looking for a new app to use in its place. I've set up Linkwarden, it's pretty decent so far, though I definitely miss how snappy Linkding is. I'm also tempted to try out one of the other options that has AI tag generation, but at the same time Karakeep does seem a bit heavy as well. I do also much prefer a list-based UI rather than the grids of Linkwarden and Karakeep. **Let me know what you're currently using and if you have any suggestions for me, thanks!**”
