Fenestra
Browser-based AI rendering for architects: turn sketches, CAD drawings, photos and 3D models into photorealistic renders and animations.
For concept-to-presentation work, Fenestra is one of the few AI renderers shaped around architecture rather than retrofitted to it. The per-credit economics are transparent at roughly 4¢ per render on Individual ($8/mo billed yearly, $16/mo monthly) and 2.4¢ on Studio ($48/mo billed yearly), and the video bench — Seedance 2.5, LTX 2.5 Fast, Wan 3.0 Prime, MiniMax H3 Max — is unusually deep for an archviz tool. The September 2026 model browser and preview thumbnails fix the hardest part of picking a model. Buy it if you iterate on facades, materials and interiors weekly; look at a Midjourney subscription or a raw model playground only if you want general imagery rather than held geometry.

Skip Fenestra if you need unmetered generation, offline or on-premises rendering, or documented API access today — its credits are metered per month and it runs in the browser.
Video burns credits roughly 10x faster than stills, so a 200-credit Individual month is about 20 videos rather than 200 renders.
Individual at $8/mo billed yearly ($16/mo monthly) sits below Midjourney and most general image tools while staying architecture-specific; Pro at $28/mo billed yearly and Studio at $48/mo billed yearly target working professionals and small practices. Team at $208.33/mo billed yearly ($2,500/yr) for five seats is cheaper per seat than most enterprise licensing, but it buys a shared credit pool rather than unlimited generations. Pure API access is far cheaper if you only need a handful of

About Fenestra
Fenestra is a browser-based rendering studio built specifically for architects and interior designers. You upload a sketch, a 2D CAD drawing, a photo or a 3D model (FBX, GLB, 3DM) and get a photorealistic render back in seconds — no render farm, no install, no model training. The company reports 20,000+ architects and designers, 200,000+ generations and 11,000+ unique projects. Four modes cover the pipeline. Create handles sketch-, CAD-, photo- and model-to-render. Edit makes natural-language changes — add people, remove furniture, swap facade materials — with rectangle select, hand-drawn brush masks, editable pen polygon masks, a reusable Masks tab and PDF import, so you can render straight from a floor plan page instead of exporting to an image first. Enhance is set by the output resolution you want (2K, 4K, 6K, 8K) with an optional face-fix pass. Animate turns a render into cinematic video using presets, and the scroll-video maker builds a frame-by-frame scroll animation you hand a client as a link. A model browser with preview thumbnails and favourites sits over roughly 70 hand-picked models: Nano Banana 2, Nano Banana 2 Lite and Nano Banana Pro for architecture, GPT Image 2, Flux 2 Pro, Qwen Image Edit and Nano Banana Editing for edits, Krea 2 and Krea 2 Turbo for stylised restyles, plus a video bench of Seedance 2.5, Seedance 2.0 at 1080p and 4K, LTX 2.5 Fast, Wan 3.0 Prime and MiniMax H3 Max. Realtime rendering (split view against your sketch), batch generation, custom style references and team workspaces with shared credit pools round it out. The difference from a general image model is geometry and regional control: it is one archviz-shaped workflow — credits, curated models, 8K upscale and commercial rights in a single browser tab — rather than a raw model playground.
Behind the Verdict
Fenestra's pitch is narrow and it holds up: a single browser tab for the archviz pipeline instead of four subscriptions and a render farm. The strongest parts are the editing controls and the model shortlist. Edit Mode now supports rectangle select for roughly rectangular fixes, brush masks for tracing the actual shape of a sofa or window, editable pen polygon masks, and a Masks tab so a mask you spent time on is reusable on the next view. PDF import means you can pick a page from a floor plan PDF, crop to the plan or elevation, and render straight from the drawing — a step most competitors make you do in Photoshop first. The model bench is where Fenestra does real curation work. Roughly 70 models are grouped by job — architecture, editing, styles, video — with a preview thumbnail and a line on what each is best at, and favourites pin to the top of every list. Nano Banana 2 Lite at 3 credits per generation is genuinely useful for getting five quick directions before committing to a finished image; Krea 2 Turbo restyles material and mood while keeping modelled geometry; Seedance 2.5 is the flagship video model with audio. Realtime rendering with a full-screen split view — your sketch on one side, the render updating on the other — is the feature that changes how you explore, because you find the idea by moving rather than by queueing. The honest weaknesses. Credits are metered, and video eats them: ~10 credits per video against ~1 per image, so the Individual plan's 200 credits is closer to 20 videos than 200 renders in a video-heavy month. Several capabilities are still labelled coming soon on the pricing page — team tools, 3D model sharing, custom model training and 3D model generation — so don't buy for those today. It's a cloud product, so offline and on-premises rendering are out of scope by design. And it is purposefully not a general graphic-design tool: it holds architectural geometry well and will not serve illustration work outside that lane. Where it fits: architects and interior designers producing client-facing visuals weekly, small studios that want shared credits and centralised billing without a per-seat enterprise contract, and students at $8/mo billed yearly with a further 20% student discount. Where it doesn't: high-volume render shops that need unmetered generation, or firms that need everything on their own hardware.

Real-world workflow fit
Concrete scenarios for the personas Fenestra actually fits — and what changes day-one when you adopt it.
You have a hand sketch of a facade and a client meeting in the morning. You upload the sketch in Create, pick Nano Banana 2 from the model browser, generate four options with batch generation, then use Edit Area rectangle select to drop in a different cladding material on the winning one.
Outcome: Three client-ready facade options in under an hour on the Individual plan, with roughly 4¢ of credits spent per render.
You are restaging a living room render and the sofa is wrong. You paint a brush mask around the actual sofa shape, type 'replace with a modern leather sofa', and re-run — the mask is saved in the Masks tab for the next angle.
Outcome: Consistent furniture across three camera angles without redrawing masks or losing the room's geometry.
You build a 30-second multi-shot film from one hero render, checking camera moves on LTX 2.5 Fast first and re-running the approved shot on Seedance 2.5 with audio. The Studio plan's 2,000 credits cover the iterations.
Outcome: A scored architectural film and a 9:16 cutdown for social, produced without a render farm or a video editor.
Use Cases
- Turn a hand-drawn sketch into a photorealistic architectural render in seconds.
- Import an FBX 3D model and generate cinematic exterior views with custom lighting and materials.
- Type 'replace the sofa with a modern leather version' and get an instant edit.
- Enhance a low-resolution client render to 4K or 8K with added detail for presentation.
- Create a 10-second cinematic walkthrough from a single render for client presentations.
- Generate a 30-second multi-shot architectural film with sound from one prompt using Seedance 2.5.
- Turn a PDF floor plan into an interior render without exporting to an image first.
- Build a scroll-driven animation from renders and share it as a link with clients.
Models Under the Hood

Limitations
- Credits are metered per plan and reset each billing cycle: Individual 200/month, Pro 1,000, Studio 2,000, Team 5,000 shared.
- Images cost about 1 credit, enhancements about 2, videos about 10 — so the Individual plan's ~20 videos/month is the real video ceiling.
- A 20% discount applies to yearly billing, which is paid upfront; monthly rates run double.
- Realtime rendering is available to everyone but limited to 1, 5, or 10 concurrent realtime sessions depending on tier.
- WebGPU is required, so older hardware is not supported.
- Team and Enterprise features — SSO, seat-based licensing, shared asset libraries, knowledge base, custom model training, data export, private cloud deployment, IP whitelisting, 3D model sharing and 3D model generation — are still listed as coming soon and should not be relied on today.
- Support is responsive but not 24/7, and there is no public status page to track uptime.
- Fenestra is a cloud product: offline and on-premises rendering are out of scope by design.

Where the pricing makes sense
The company stage and team size where Fenestra's pricing actually pencils out — and where peers do it cheaper.
Individual at $8/mo billed yearly ($16/mo monthly) sits below Midjourney and most general image tools while staying architecture-specific; Pro at $28/mo billed yearly and Studio at $48/mo billed yearly target working professionals and small practices. Team at $208.33/mo billed yearly ($2,500/yr) for five seats is cheaper per seat than most enterprise licensing, but it buys a shared credit pool rather than unlimited generations. Pure API access is far cheaper if you only need a handful of
Setup time & first value
How long it actually takes to get something useful out of Fenestra — broken out by persona, not the marketing-page minute.
Create a free account and the studio loads in the browser — most architects produce a first render in 10-15 minutes, and the 5 signup credits cover the first few attempts. Getting a usable sketch-to-render in your own style takes about an hour, including a custom style reference. Team rollout with shared credit pools and seat assignment is a day, mostly spent agreeing on which models the studio
Switching to or from Fenestra
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a render farm or V-Ray/Enscape workflow: upload the same sketch, CAD drawing or FBX/GLB/3DM model you already export, and produce concept renders in the browser without touching your production pipeline.
- →From Midjourney or another general image model: re-upload your signature style as a custom style reference so the look carries over, then move to Fenestra's architecture-grouped models for geometry that holds.
- →From manual Photoshop editing: replace layer-based retouching with Edit Area prompts, brush masks and the reusable Masks tab on the same render.
- →From emailing render files to clients: rebuild the sequence in the scroll-video maker and send a link instead.
- →From juggling several model subscriptions: consolidate onto the model browser's ~70 curated models with preview thumbnails under one credit balance.
- ↗To a traditional render farm or offline renderer: export your Fenestra renders and re-render hero shots in your own pipeline when you need on-premises or unmetered output.
- ↗To a general image generator such as Midjourney: carry over your custom style reference, though you lose region-level Edit Area control and credit-based archviz model curation.
- ↗To a documentation or BIM platform: measured, dimensionally accurate drawings still need to be produced in your drafting tool, since Fenestra's models hold composition rather than scale.
- ↗To a dedicated video editor: export the generated clips and finish the film outside Fenestra if you need frame-accurate cutting beyond the multi-shot workflow.
