## Stable Horde

Stable Horde works on a contribute-and-consume model. Volunteers run workers on their own GPUs, and those machines become the compute pool for everyone else. Users submit prompts through the browser interface or the REST API, and the horde routes the job to available workers, returning generated images or text. Because the hardware is donated, generation is free rather than metered per image.

The project is explicitly open source and non-profit oriented: it is run by Haidra, a volunteer-run organisation, and funded by public donations plus NLnet / NGI0 Core. Multiple model families are available on the image side, including Stable Diffusion XL variants, Juggernaut XL, DreamShaper XL, Stable Cascade, Cheyenne and Flux.1-Schnell, alongside text generation. There is also an "alchemy" mode for post-processing work such as upscaling and face fixing.

Alongside generating, users can register accounts, join as workers, transfer and earn kudos (a priority currency earned by contributing compute), and use a broad ecosystem of third-party GUIs, tools and client libraries built on the documented REST API. The horde publishes live status showing workers, queue depth and throughput across image, text and alchemy pipelines.

**Pricing & Plans:** 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.

- **Crowdsourced distributed compute:** Volunteer-run workers on donated GPUs form a shared cluster, so generation costs users nothing.
- **Image, text and alchemy pipelines:** Generate images across multiple Stable Diffusion-family models, generate text, or use alchemy for upscaling and face fixing.
- **Full REST API:** A documented REST API with an ecosystem of third-party GUIs, tools and client libraries for building on the horde.
- **Kudos priority system:** Earn kudos by contributing compute and spend them to move your own requests up the shared queue.
- **Open source and community governed:** Run by the volunteer non-profit Haidra, with public live status, open code and donation-based funding.

**Strengths:** Free to use, with no per-image or subscription charges; Wide choice of image models and text generation under one interface; Documented REST API plus a large third-party tool ecosystem; Open source, non-profit and openly funded

**Limitations:** Queue wait times depend on how busy and how large the volunteer pool is; No SLA or guaranteed capacity since compute is donated; Interface and documentation are aimed more at technical users

## UserAPI.ai

Midjourney has no official public API, so teams that want image generation inside their own products usually need a workaround. UserAPI.ai fills that gap as an independent, unofficial API: it accepts a prompt and returns generated images, exposing the familiar Midjourney methods as REST endpoints you can call from your backend.

There are two ways to generate. With your own Midjourney account you add a Discord token once and pay Midjourney for your plan; UserAPI access costs $0.04 per request or $25 per month, and this route is cheaper above a few hundred images a month and supports speed mode and multiple accounts. With UserAPI Cloud you need no Midjourney subscription and no Discord token — Generations run on UserAPI's accounts at $0.08 per image, with failed tasks refunded automatically, which is a fast way to test.

The service supports the core Midjourney toolkit: Imagine, Upscale, Variation, Blend, Describe, Animate, Upsample, Pan and Inpaint. It ships documentation, code examples for Python, Node.js and PHP, and no-code integrations for n8n and Make.com. It is explicitly not affiliated with Midjourney Inc., so evaluate the account and reliability risks of unofficial access before building it into production.

**Pricing & Plans:** UserAPI.ai offers a free pack of 50 requests with no card. Using your own Midjourney account costs $0.04 per request or $25 per month (or $67.50 per quarter and $246 per year), while UserAPI Cloud runs on UserAPI's accounts at $0.08 per image, a 60% discount off the $0.20 launch rate, starting from $3 (about 37 images), with failed tasks refunded automatically.

- **Full Midjourney method coverage:** Call Imagine, Upscale, Variation, Blend, Describe, Animate, Upsample, Pan and Inpaint through a REST API for scripted image generation.
- **Cloud generation without Discord:** Generate without a Midjourney subscription or Discord token by running on UserAPI Cloud accounts, with failed tasks refunded automatically.
- **Multi-account admin panel:** Manage multiple image generation accounts, schedules and keys from a single admin panel.
- **Code examples and no-code integrations:** Ready code samples for Python, Node.js and PHP, plus official integrations for n8n and Make.com automations.
- **Free pack and flexible plans:** Start with a free pack of 50 requests and move to pay-per-request or monthly plans as volume grows.

**Strengths:** Brings Midjourney image generation into your own app without an official API; Cloud option works with no Midjourney subscription and no Discord token; Covers the main Midjourney methods, including Inpaint, Blend and Animate; Code examples for Python, Node.js and PHP plus n8n and Make.com integrations

**Limitations:** It is an unofficial API and is not affiliated with Midjourney, so it depends on platform behavior it does not control; Using your own Midjourney account still requires a Midjourney subscription and a Discord token; Because it relies on Discord accounts, automated usage carries account-risk considerations; Cloud pricing is per image and can add up at high volume
