How do their growth rates compare?

Runware has a month-over-month growth rate of +27.1%; Stable Horde has +176.5%.

How does pricing compare?

Runware: Paid. Pay-as-you-go with no subscription required. Managed inference is billed per generation, per second of video, per character of audio, or per 1M tokens for LLMs; published rates include examples such as FLUX 3 Image Klein from about $0.003 per image and GLM-5.3-Flash at $0.15 per 1M input tokens. Serverless GPU compute is metered by the second (RTX PRO 6000 listed around $1.99 per GPU-hour) and scales to zero; reserved capacity is advertised as low as $0.63 per GPU-hour on term commitments, with dedicated bare-metal clusters available from 72 GPUs. Failed or rate-limited requests are not charged, new users signing up with a business email receive $2 in free credits, and volume discounts are available via sales. Stable Horde: Free. Completely free. Compute is donated by volunteers; there are no paid tiers or per-image fees. Contributing compute earns kudos, which raise your priority in the queue. The project is funded by public donations and NLnet / NGI0 Core.

Runware

One API for 400K+ AI models, plus serverless and reserved GPUs on modular data centers

One API for every modality

Image, video, audio, LLM and 3D tasks all POST to a single endpoint as an array, so mixed-modality batches can travel in one request with shared auth and billing.

400K+ model catalog

Browse hosted, partner and community models through one addressing scheme, control parameters such as stacked LoRAs and swapped VAEs on open models, and add your own uploads.

Serverless and reserved GPU compute

Bring your own container and weights to serverless GPUs billed by the second that scale to zero when idle, or commit to reserved capacity and bare-metal clusters for a lower per-hour rate.

Sonic Pods and the Sonic Inference Engine

Purpose-built modular data centers plus an orchestration layer that keeps weights preloaded across regions and routes requests to pods that already hold the model in memory.

Strengths & Pros

+Unusually broad catalog — hundreds of thousands of models behind one consistent endpoint and API key
+Aggressive published pricing, with claims of up to 10x lower cost per generation than market rates
+Both managed inference and raw compute in one platform, so you can migrate from API calls to your own containers without changing vendors
