Does having a public API matter if I only need occasional images?

Less so for occasional, manual use, but it matters a lot for any agentic or automated workflow — Midjourney, for example, has no public API in this category's data, which rules it out for programmatic generation regardless of output quality.

Is an open-source model always cheaper than a hosted one?

Not necessarily upfront — Black Forest Labs, the one open-source vendor in this category, doesn't publish a flat entry price because it bills per-megapixel via API, with self-hosting as a separate licensing tier. Self-hosting avoids per-image API fees but adds infrastructure cost and operational work.

Choosing a generative image tool

Whether you can self-host the model, and what you're actually licensed to do with the output, matters more here than which tool makes the prettiest demo image.

Six vendors in this category can all generate a convincing image from a text prompt today, so the decision that actually differentiates them isn’t image quality — it’s whether you can run the model yourself, whether there’s a programmatic way to call it at all, and what usage rights you’re actually buying alongside the pixels.

Only one vendor here is open source and self-hostable

Black Forest Labs is the sole vendor in this category tagged open source, and it’s also the only one offering self-hosted and on-prem deployment alongside its cloud API — billed per-megapixel rather than a flat monthly fee, with separate open-weight and self-hosted licensing tiers. Recraft, Ideogram, Stability AI, Leonardo.Ai, and Midjourney are all cloud-only in this dataset. If keeping generation in-house or controlling exactly which model version runs matters, Black Forest Labs is the only current candidate in this set.

API access varies from full to nonexistent

Recraft, Black Forest Labs, Ideogram, and Stability AI all offer a pay-per-use or credit-based developer API, and three of those four — Recraft, Black Forest Labs, and Ideogram — also ship an MCP server (Recraft and Black Forest Labs with a public repo). Midjourney, by contrast, is sold purely as flat subscription tiers with no public API at all, which makes it a non-starter for any agent-driven or automated image-generation workflow, whatever its output quality.

Pricing spread and agent-readiness

Among vendors with disclosed monthly pricing, Recraft ($12/month) and Midjourney ($10/month) sit at the low end, Ideogram at $15/month, and Stability AI notably higher at $50/month. Agent-readiness tracks a similar spread in this set — Recraft leads at 82, Black Forest Labs close behind at 81, down to Midjourney at 35, the lowest in the category, consistent with its lack of API access.

The Generative Image AI category page lets you filter by deployment model and open-source status, and Recraft vs. Black Forest Labs is a direct comparison between the category’s top-ranked hosted and open-source options.
