Hey Product Hunt 👋
We’re excited to finally share Voltage with you ⚡
Voltage is an open-source, self-hosted, FFMPEG-based video encoding API built for teams that need full control, scalability, and predictable costs when processing video at scale.
We originally built Voltage to power the video infrastructure behind RADAAR, our AI-powered social media automation platform. Over time, it grew into a fully featured system with multi-instance scaling, job queues, storage-agnostic uploads, and AI capabilities — and we realized it could be useful for many others building video-heavy products.
What makes Voltage different:
🧩 Fully open-source (MIT) — no vendor lock-in
🚀 Multi-instance & horizontally scalable by design
🎛 Deep FFMPEG customization (per job & per output)
🧠 Built-in AI: Whisper transcription & NSFW detection
💾 Storage-agnostic (local, S3-compatible, FTP, SFTP, etc.)
💸 No per-minute fees — you only pay for your infrastructure
Voltage is a great fit if you’re building:
A social media or UGC platform
A video CMS or SaaS product
An internal media processing pipeline
Anything where video is a core capability, not an afterthought
We’d love your feedback 🙏
What features would you want most from an open-source video encoding platform? What would stop you from self-hosting something like this?
Thanks for checking it out — and happy to answer any questions!
