From the founder
I built ReelStack because I was spending 4 hours editing a 30-second reel. I knew the script. I knew the style. I just needed a machine to assemble the pieces. So I wrote one. ReelStack started as a bash script, grew into a Remotion pipeline, and now it is an open platform that anyone can extend. If you make content at scale, this is for you.

Integrations
FAQ
No. The web dashboard lets you write a script, pick a voice, and hit render. The API and CLI exist for developers who want automation, but they are optional.
A typical 30-second reel renders in 15 to 40 seconds on AWS Lambda. Local Docker renders depend on your hardware but average under 2 minutes.
ReelStack ships with 19 integrations, but the module system is open. You can write a custom provider for any tool that has an API.
You run ReelStack on your own server with Docker. Your data never leaves your infrastructure. No cloud account required, though Lambda rendering is available as an optional accelerator.
3 full renders per month with all effects and AI Director. The free tier includes a small watermark. Upgrade to Solo ($9/mo) to remove it.
Those are editing tools. ReelStack is a rendering pipeline. You do not drag clips on a timeline. You write a script, the AI plans the video, and code renders it. Built for volume, not one-offs.
Yes. ReelStack supports both 9:16 vertical (Reels, TikTok, Shorts) and 16:9 horizontal (YouTube). Same effects, same pipeline.
You keep the open source core forever. Premium modules you purchased stay yours. You just lose access to future module updates and priority Lambda rendering.
Yes. The Agency plan includes no branding on renders and API access for multi-tenant setups. Many agencies resell the output directly.
GitHub Issues for bugs, Discord community for questions, and priority email support on Pro and Agency plans.
