Midjourney vs Krea, compared honestly

Pick Midjourney if you want the most striking concept imagery and a consistent look across a set of boards; plans start at $10 a month and there is no free trial on the website. Pick Krea if you want to start free, generate in real time as you draw and upscale in the same app; the free plan gives 100 compute units a day and paid plans start at $9 a month. Both run in a browser, so a Mac is fine.

Neither is built to render the building you already modelled. To turn a 3D model or a sketch into a render, Render a House is the alternative: browser-based, no GPU, about 30–60 seconds, free for 3 renders a day. It is not an open-ended image generator. Last updated: September 25, 2026.

From each vendor’s own pages, checked September 2026: Midjourney plans, Midjourney GPU speed, Midjourney versions, Krea pricing and Krea’s homepage.

First, credit where credit is due: for mood and atmosphere, Midjourney is the tool many architects reach for first. Its case is image quality, style control and a flat monthly price.

One look across a whole set

Moodboards turn curated images, uploads or URLs into a project style, so every board in an entry reads as one family, per Midjourney moodboards.

Unlimited images at a flat price

Standard is $30 a month with 15 Fast hours and unlimited Relax images, per Midjourney plans. You wait in a queue instead of paying per image.

HD stills and very wide frames

V8.2 has been the default since July 24, 2026, per Midjourney versions. HD images reach 2048 px without upscaling, and aspect ratios run to 14:1 (4:1 in HD).

Krea’s case is a free way in, speed of iteration and many tools under one plan.

A free plan with no card

100 compute units a day with no credit card, and paid plans from $9 a month, per krea.ai/pricing. Midjourney has no free plan on the web.

Real-time generation as you draw

Krea Realtime updates the image as you sketch or type. Good for loose massing studies.

Video, 3D and upscaling in one plan

Paid plans cover image, video and 3D models plus upscaling to 22K, with no second subscription, per krea.ai/pricing.

US list prices, checked September 2026, from Midjourney’s plan docs and Krea’s pricing page. Midjourney’s own pricing page returned a 404, so these figures come from its documentation. Midjourney bills in GPU hours; Krea bills in compute units, so the two do not convert one to one.

It depends on what you deliver and what you start from.

Competition boards or a first client pitch

Midjourney Standard: unlimited Relax images and moodboards for one coherent look. Companies above $1M a year in revenue need Pro or Mega (see Midjourney plans).

A student or a zero budget

Krea Free for loose exploration, with no card (see krea.ai/pricing). Add Render a House Free to render your own sketch.

Massing ideas from a napkin sketch

Krea Realtime, to try many directions quickly. To keep the building you drew, use sketch to render instead.

A SketchUp, Revit or Rhino model to show

Neither. Export a GLB or screenshot the view and upload it to Render a House for a concept render in about 30–60 seconds.

Midjourney and Krea are image generators, not 3D modellers: Midjourney treats your images as inspiration rather than copies. Render a House starts from the model or sketch you already have and renders that design.

Render a House is an AI rendering tool for architects, interior designers and real estate. Export a GLB, GLTF or OBJ from SketchUp, screenshot a Revit, Archicad or Rhino view, or photograph a hand sketch, and get a concept image in about 30–60 seconds.

What it cannot do

• Give you a live viewport or real-time canvas. Each render takes about 30–60 seconds.
• Produce measured drawings or BIM data. Check proportions against the model.
• Run as a plugin inside SketchUp, Revit or Archicad. Export a GLB or screenshot the view; .skp is not accepted.
• Replace a final production render. It makes concept images, and geometry can shift.

Midjourney wins on image quality, style consistency and unlimited Relax images from $30 a month. Krea wins on the free plan, real-time generation and having video, 3D and upscaling in one subscription. Try Krea free first; pay for Midjourney if you need its look.

For a concept render of a design you have already drawn or modelled, Render a House is the better fit: it runs on any machine, takes about 30–60 seconds and is free for 3 renders a day. More on that workflow: sketch to photorealistic render with AI.

Is Midjourney better than Krea?

For striking concept images with one consistent style, Midjourney is usually stronger. Krea is better for a free plan and real-time generation from a sketch. Neither renders a 3D model you already built.

Is Midjourney free?

No. There is no free trial on the website or Discord, only a limited one in the niji·journey mobile app. Basic starts at $10 a month.

Is Krea free?

Krea has a free plan with 100 compute units a day and no credit card. Paid plans start at $9 a month for Basic, or $5 a month billed yearly.

Does Krea run on Mac?

Yes. Krea is a web app, so it runs in a Mac browser, as do Midjourney and Render a House. None of the three asks for a local graphics card.

Can I use Midjourney without a 3D model?

Yes. It works from a text prompt, optionally with image prompts or moodboards. It treats your images as inspiration, so it will not keep your exact design. To keep your geometry, render the sketch or model in Render a House.

What is the best alternative to Midjourney and Krea?

For turning a 3D model or a sketch into a render, Render a House: browser-based, no GPU, about 30–60 seconds, free for 3 renders a day. For open-ended image exploration, stay with Midjourney or Krea.
