Show HN: OSS Web Based AI Video Studio (Vivijure)
Hello Everyone!
So I wanted to introduce everyone to an AGPL-3.0 OSS, free forever, AI Video Studio that I've been working on for the past few months called "Vivijure." Vivijure is a web based modular frontend that allows you to collaborate with AI to plan your videos, create images of your cast members and generate all the images for a full LoRA training set, and render your videos either on your own iron (LTX Video) or rent by the second serverless workers (Wan 2.2). It also has integration with several Cloud i2v providers through the interface and everything gets planned in a standard storyboard.json format. I've integrated Real-ESRGAN for video upscaling, MuseTalk for lip syncing your characters to their spoken lines, audio upscaling for speech (GPU based) and music (CPU based). The really cool thing that I've implemented for the design is it's not wasteful when it comes to your GPU spend, anything that can be done by a CPU only, Vivijure routes the job to one of its CPU worker pods instead of you wasting your money or electricity running a CPU-centric job on a GPU.
There's also a Discord Bot I've designed to go with it called Slate that allows you and your friends to plan, research, and render videos together on your own Discord Server. Vivijure supports create title and credit cards, subtitles, narration, music generation, and timing your shots to music that you upload yourself.
Right now the front end control panel runs as a Cloudflare Worker, along with the modules, and it connects to R2 and D1 for data processing and storage. Anybody can write a module as long as it follows the contract set out (and extensively documented). I'm working on a cloud agnostic version of the control panel as part of the next major release, but for now, the front end is Cloudflare powered and for the basic set of modules you can host it for free. To integrate the video upscaling, MuseTalk, and speech upscaling modules you do have to upgrade to Cloudflare's Workers Paid plan, which is $5/month.
There's a limited demo that I've setup if you would like to see how the interface looks and feels at https://demo.vivijure.com. You can find more info, including a "ask me anything about Vivijure" widget at https://vivijure.com, and as always, the source code is available at https://github.com/skyphusion-labs/vivijure.
I really look forward to people checking this out and trying it out, I really enjoyed working on Vivijure and it's my gift to the world - free yourself from SaaS AI Video Studio providers, regain your privacy and control over your own data, and most of all, be creative without being gated by entities that want to limit your vision. There's an easy to use installation script that comes with Vivijure, it should take you no more than an hour to be fully operational with it.
If anyone has any feedback, questions, or comments, please let me know. I'm very excited to show this to the world and I hope someone could gain good use from this software.
Thanks,
Skyphusion (Conrad Rockenhaus)

Show HN: Costbase – See what each of your AI apps costs, without a proxy
Live demo, no signup: https://costbase.co/demo
Hi there, over the past 1-2 years I've built and experimented with many AI apps. Some are in production, some died in the experimental stage.
The ones in production currently costs me ~$500 a month to run – using a variety of models from OpenAI's Whisper to Anthropic LLM.
Because it's important for me to track the Cost of Goods Sold of each individual app, the strategy I've used so far is to use a different credit card for my few apps. However, that obviously does not work the more apps I build.
This is why I built Costbase – a simple app that just requires that I paste in an admin key with no code change (and no proxy sitting between my app and the AI provider) – and show me the cost of my AI bill broken down by apps and not API keys.
I intentionally kept this product as simple as possible – something I would actually like to use. I know there are observability tools like Helicone that are much more capable. But to be honest I didn't even try out the competitor and just built something I'd like to use myself.
I'd like to hear from the community to see if anyone feel a product like Costbase is genuinely useful.
Let me know your thoughts in the comments.
(I'm in Taipei so going to sleep in about two hours. Will be back tomorrow morning to answer any additional comments)

Show HN: Aco – Appium Command-Line Operator
Hi, I created a CLI tool called aco to help spin up Appium session rapidly.
I'm a programmer who've been working on mobile app automation for end-to-end testing for years. Appium is the industory standard in this area. It's basically a WebDriver protocol server spetiallized for non-browser apps like iOS/Android. The beauty of Appium is its clean separation of the responsibility by the client/server architecture. So consumers select any language binding they like when use it. It means you typically need to care of server and client at the same time, and this is the pain.
As a mobile automation engineer, I often need to run a small experiment to make sure of the behavior of AUT(application under test) or Appium itself: how long does it take to fetch page source from a complex screen, how much ScrollView moves to a specific swipe amount, what's hapenning behined the sceen when some letters are dropped from text sent, etc. When it comes, I usually write a small script tp send commands to server, spin up an Appium server, run the script, and then observe the result. It's not so hard but a bit hussle as I need to recall required parameters to give to the server and wire them up just to see actual interaction.
aco makes it significantly compact. You just need to specify your app file and platform from CLI. That's it. The core idea is packing server launch and session initiation in a single command. The other point is that aco is designed as stateful. Session is stored on disk and implicitly picked up so you don't have to care about it when consuming.
$ aco session start --platform ios --app ./your_aut.app.zip --detach {"sessionId":"0134d269-eb58-4569-97d0-446c5e808fd4","serverUrl":"http://127.0.0.1:4723","platform":"ios","pid":21762} session detached -- pid 21740, stop with `aco session stop` $ aco elements #0 XCUIElementTypeApplication "Some label" selector: accessibility id:Some label rect: 0,0 402x874 ...... #58 XCUIElementTypeStaticText "Other label" selector: accessibility id:Other label rect: 172,630 57x19 $ aco tap --selector 'accessibility id:Other label' ok
I tried to map out all Appium features including iOS/Android specific extension into the CLI. Plus, I added some utility features like the `aco element` which lists all accessible elements with ready-to-use selectors. I'd appreciate bug reports or feedback. Thanks!
