Pricing

Transloadit is a SaaS with a subscription model.

Our /audio/waveform Robot counts towards your Plan's data at a normal rate. It does charge a minimum of 1MB whenever it is used. Assuming an average input audio file of 3.8MB and an output of 3.04MB, that would still have a minum charge of 1MB, so here's what it would approximately cost to generate audio files per Plan:

Plan Price Costs per file within your Plan Overage Fee
Sandbox (2GB) Free $0.0
to generate 2048 audio files
N/A
Startup (10GB) $49/month $0.0048

Just like with your mobile plan, pricing goes down when you commit to larger monthly volumes. When you reach your plan's limit, we'll continue to service you, but remind you to upgrade to more cost-efficient plans. This is unless you explicitly set budgets. You can change plans at any time.
