openGym
openGym is a gym and body-weight tracker that lives on your phone. Plan your routines and a weekly schedule, then log each session as you train: sets and reps, supersets, cardio and timed holds. openGym works out the next step for you with automatic progression (linear, double or time-based), so you walk in knowing what to lift.
The exercise library comes with pictures and animations, stats show how each lift and your body weight are trending, and you can bring your history with you from Strong, Hevy, FitNotes, a CSV file or Apple Health weight. Plans can be saved as files and shared with a training partner, who imports them in one go. Sign-in uses passkeys, so it's your fingerprint or face rather than another password.
When does hosted openGym make sense?
- You want your training log to belong to you, not to a fitness app's account that can change its price or shut down.
- You train with the household. Everyone gets their own profile on your instance, with their own plans and history.
- You want passkeys to just work. They need a real HTTPS address, which your instance has from day one.
- You'd like a coach without a subscription. openGym's AI Coach drafts plans and reviews your progress, and it works with the AI included with your plan.
- You don't want to babysit it. We keep openGym updated and back it up daily, with restores you can run yourself from ElfBot.

How do I access openGym?
openGym is available:
- From your dashboard: https://your-username.elfhosted.com
- Directly: https://your-username-opengym.elfhosted.com
Signed-in users see their own URLs
The addresses above show the general pattern. Sign in and these become your personal, clickable links.
How do I use it?
Create your profile first
openGym has its own sign-in, and there's no ElfHosted login in front of it. The first profile created on your instance becomes its admin, so open openGym as soon as your instance is ready and create yours. Your device asks to save a passkey (fingerprint, face or your phone's screen lock), and that's your login from then on.
After that first profile, sign-up is invite-only: nobody can create a profile on your instance without a code from you.
Add the rest of the household
- In openGym, open Settings, then Account, then Admin dashboard.
- Create an invite code and send it to the person you're inviting.
- They open your openGym address, enter the code and create their own profile, with their own passkey.
Each profile has its own plans, logs and stats.
Put it on your phone
The quickest way is to open your openGym address in your phone's browser and add it to your home screen. It then opens like an app, and can send you push reminders for training days.
On Android there's also a native app, downloaded from the openGym releases or the openGym website rather than the Play Store. To connect it to your instance:
- In openGym in a browser where you're signed in, open Settings, then Account, and choose Pair the mobile app. It shows a one-time code, valid for five minutes.
- In the app, choose to connect to your own server, and enter your openGym address and that code: https://your-username-opengym.elfhosted.com
The app keeps working offline, and catches up with your instance when it's back on a network. On an iPhone, add openGym to your home screen from Safari instead.
Bring your history with you
openGym imports workout history from Strong, Hevy and FitNotes, plain CSV files, and body weight from Apple Health. You can export everything again whenever you like, so your data is never stuck.
Is AI included?
Yes. openGym's AI Coach is built in and stays off until the admin switches it on. It proposes a plan from your goals and schedule, and later reviews how your training is going. Nothing changes until you accept a suggestion, and accepting one adds the routines while keeping a snapshot of your previous plan.
To set it up with the AI included with your plan:
- In openGym, open Settings, then Account, then Admin dashboard, and find the AI Coach card.
- Choose OpenAI-compatible endpoint as the provider.
- Set the endpoint to
http://elfhosted-internal.bree/v1and leave the key empty. - Pick the model from the list it shows.
- Click Test the Coach, then Set up the Coach.
Everyone on your instance then finds it under Plan, then Coach. It runs on an allowance included with your plan. If you'd rather use your own Anthropic, OpenAI or Google Gemini account, or another OpenAI-compatible service, choose that provider on the same card and enter your own key; its usage is then billed by your provider directly.

What users say..
We're rocking some excellent 
TrustPilot Reviews, and here's what some of our usersfriends say..
I am new here, but today I learned realized that Elfhosted is one of the best free and open source software communities I've seen, and FOSS communities have been at the center of my life since the 90s (Perl, PHP, Symfony, Drupal, Ethereum, etc.). Great open software built by great people who care = great community, and that is something special.
You've done an amazing job @Funky Penguelf with the platform you provide and this place has an awesome mix of active community caretakers and software creators that I've seen here so far like BSM, Spoked, LayeZee and other elf vengers. Keep up the energy, productivity and community and take time to enjoy it and appreciate each other!
As a happy Elfhosted customer—who also self hosts MANY things across about 10 severs (dedicated, VPSes, and VMs running on Synology), I wouldn’t switch to self hosting the services I get from Elfhosted. They just work with very little effort configuring things, and the support the owner and his team provides is second to none. Plus I love being part of a fledgling—but quickly growing—enterprise.
I’ve been using this service for a while now, and honestly, it’s a game-changer compared to anything else I’ve tried for managing my media library. The support is fantastic—super quick, and if the staff aren’t around (which rarely happens), the community steps up right away. I can’t imagine going back to any other platform.
Before this, I had my own setup with a NUC, NAS, and tools like Sonarr and Radarr. It worked pretty well for a while, and my internet speed was high enough to stream without any buffering. But in the end, it wasn’t worth the time or headache of managing all the storage and keeping everything running smoothly.
Now, with this service, everything runs smoothly in 1080p+ with no buffering issues. The interface is really easy to use, which makes managing everything a breeze. Plus, having a whole community of smart people available for guidance is a huge bonus.
I was sold from the start, which is why I quickly upgraded from a 1-month to a 3-month subscription, and I’m planning to switch to a 1-year plan soon. This service totally pays for itself, and I’m sure you won’t be disappointed. It’s been really impressive.
Best possible options for anyone looking for the do-it-all option along with the best customer service ive experienced in this space so far. Id rate it a 6 if I could but its limited to 5/5...
(responding to a discussion re the cost of ElfHosted vs mainstream streaming / self-hosting):
I didn't know that the goal of this project was to compete with large companies running/renting entire DCs. I was under the impression that the goal of this project was to manage the updating of almost selfhosted applications on a shared platform with other users. Basically, be my sysadmin for me.
That being said, paying for services is the 'easy button'. There is a real world cost incurred for the time saved. Time is money. Time is the most valuable currency that exists. Once time is spent, it's forever lost, one cannot retrieve it again (yet). In my mind, there are 3 options for use of time with respect to: mainstream, selfhosting, elfhosted.
mainstream - my time is valuable and I don't want curated content and I don't care what content that I have the ability to consume. I only like what's popular.
elfhosted - my time is valuable, I want my own curated content without being forced to browse past the same damn entry 500 times just to find out that I can't watch the movie I want because it's not available in my current location or was removed last week from mainstream providers.
selfhost - I care about costs and I have nothing but time to waste or I want to learn about the backend of the systems involved. I'll pay for my own VPS/homelab, electricity, manage the OS, manage app updates, figure out how to make the apps talk nice to each other, create my own beautiful frontend.
I know how much my time is worth, does that reddit poster know how much their time is worth? Without knowing what you are worth, you can't make effective capital expenditures with respect to the time it will take to recoup the capital.
I know I don't need elfhosted at all for my use case. I choose to stay with elfhosted because it's my 'easy button'. It's an efficient capital expense for the amount of time it saves me managing my own hardware, apps and saves me electricity costs. I'm also in a situation where I don't have upload bandwidth from my home to serve HD content to myself remotely. If I lived back in a city, I would still be here. My time is worth $$/hr.
"Just wanted to check in here and let @Darth-Penguini and anyone/everyone else know...WOW. I have been struggling with storage for years, maintenance of Docker containers, upkeep, all of it. Elfhosted is so freeing. It's an amazing service that I hope to be a member of for a long, long time!"
"I would recommend ElfHosted to anyone. It has been great so far and made life a lot easier than running my own setups. If you’re in the fence give them a try and help support this great community."
