The 7 Best Node-Based Canvas Tools for AI Workflows in 2026

Key takeaways

• Melius is the best pick for getting a working graph with the least setup. Its agent builds and rewires the nodes from a plain request, and the canvas is multiplayer by default.

• ComfyUI is the pick for total control. Its Desktop app is free and open source, and it's the only tool here that runs offline on your own GPU.

• Figma Weave is the pick for compositing and editing. Its nodes include relight, inpaint, outpaint, and z-depth extraction.

• Krea Nodes turns a graph into a simple app. Teammates run a form instead of the wiring.

• Check what each plan includes. The API sits behind Enterprise on Figma Weave and behind Starter on FLORA, and real-time collaboration is a Business feature on Krea.

What a node canvas gives you

In a node canvas, each step of a creative pipeline is a box with its own prompt, model, and settings, and lines carry one step's output into the next. You can change an early step and rerun everything downstream, branch a graph to compare two versions, save a working graph and reuse it, and hand it to a teammate who didn't build it.

This guide covers canvases built for AI image, video, and audio work. General whiteboards aren't included, and neither is TouchDesigner, which is a real-time node tool for interactive visuals and not a generation canvas. For model access across tools, our guides to Higgsfield alternatives and image-to-video generators cover it.

How we ranked

We ranked each tool on how much of a creative pipeline its graph lets you build, rerun, and hand off without code, weighted by how fast someone who isn't an engineer gets there. Tiebreakers were the models available on one plan, collaboration, API access, and price clarity.

The seven tools compared

1. Melius - Best for a working graph with the least setup

Melius is a hosted canvas where an AI agent builds and rewires the graph from a plain request.

What works: Nodes cover text, image, video, and audio generation, plus file, custom text, router, and group nodes, and the connections between them are typed by media. The agent, Mel, wires the nodes, picks a model for each step, and leaves every prompt editable. Every canvas is multiplayer by default, with live cursors and AI agents showing up as participants, and outside agents can connect through MCP while a REST API and a command-line tool edit the same canvas. The model catalog lists 112 models on one subscription, each node keeps a version history, and a compare view puts two outputs side by side. Read-only share links need no account to view, and a finished workflow can be reused as a template. Creator plans start at about $17 to $20 a month.

What doesn't: Melius is free to sign up for, but generating needs a paid plan or a credit pack. It's hosted only, with no self-hosting and no custom-node ecosystem. Wiring a graph by hand still means learning typed handles and per-node credit costs.

Best for: Teams that want a working graph without building it node by node.

2. FLORA - Best for design teams that want dollar-metered usage

FLORA is a canvas of nodes for text, image, video, and audio models, with a layer editor on the same surface.

What works: It runs more than 60 models from one pool, and you can save a working flow as a reusable technique. An assistant called FAUNA is free on every plan. Each seat's included usage equals its plan price in dollars, pooled across the team by default, so cost per generation is easy to read. Starter and above add an Action node, API access, and an MCP connector. Starter is $18 per seat a month, with 20% off for yearly billing.

What doesn't: The free plan covers text and image models only, with 3 projects and up to 17 free generations. Starter keeps generation history for 30 days, and SSO and SAML are Enterprise only.

Best for: Design and brand teams that want a per-generation dollar cost.

3. Figma Weave - Best for compositing and editing

Figma Weave, formerly Weavy, describes itself as AI models and professional editing tools in one node-based platform.

What works: Its editing nodes include relight, inpaint, outpaint, crop, mask extractor, z-depth extractor, channels, and painter, alongside layers, type, and blend modes. A workflow can become a simplified interface for teammates, and Figma Weave states SOC 2 Type II certification on its site. The free plan gives 150 credits a month, a commercial license, and 5 workflows. Starter is $17 a month billed annually ($24 monthly) for 1,500 credits, and the Team plan pools credits at $42 per user billed annually.

What doesn't: Running workflows through an API is an Enterprise feature. The editing vocabulary, with z-depth and channels, makes for a steeper start if you're not a designer.

Best for: Creative professionals who composite and edit and don't only generate.

4. ComfyUI - Best for total control and local runs

ComfyUI is the open-source graph editor behind most open image and video workflows.

What works: The Desktop app is free, the code is GPL-3.0, and the site claims more than 60,000 nodes. Partner nodes reach hosted models, and you can run everything offline on your own GPU. Comfy Cloud adds hosted GPUs, and its Comfy Agent plans, builds, and runs workflows from a description. Standard is $16 a month billed yearly ($20 monthly), Creator is $28 billed yearly and lets you import your own models and LoRAs, and every paid plan includes API access.

What doesn't: ComfyUI has the steepest learning curve on this list, since you assemble samplers, models, and nodes yourself. Shared workflows and projects on the Team plan are marked coming soon, so teams pass exported workflow files around.

Best for: Technical creatives who want total control or local runs.

5. Krea Nodes - Best for turning a graph into a simple app

Krea Nodes puts inputs on the left, parameters inside the node, and outputs on the right, with color-coded handles.

What works: Node types cover image generation, video generation, image editing, enhancing, 3D, motion transfer, lipsync, audio, and utilities. Node Apps package a workflow as a simple interface with a custom input form, public or private, and an API endpoint runs them. Nodes is listed on every plan including Free, which gives 100 compute units a day. Paid plans start at $9 a month for Basic.

What doesn't: Krea's docs say some utility nodes need Pro. Collaborative canvas editing belongs to the Business plan, which lists at $200 a month.

Best for: Teams that want to hand a finished workflow to people who won't touch the graph.

6. Magnific Spaces - Best for marketers who already buy stock and upscaling

Magnific, formerly Freepik, runs a node-based canvas called Spaces for real-time collaboration.

What works: Nodes fall into media, text, image, video, audio, utilities, and designer categories, and tooltips show each node's credit cost before it runs. A template gallery lets you copy a ready-made workflow, and you can share a Space by email or link with view or edit permission. Spaces is included on every individual plan alongside API access, a commercial license, and more than 250 million stock assets. Premium is $14.50 a month billed annually ($20 monthly).

What doesn't: The pricing page shows no free plan. The unlimited-generation tier on Plus covers a listed set of models and not the whole catalog.

Best for: Marketers who already buy stock assets and upscaling from the same vendor.

7. Scenario - Best for studios that train their own models

Scenario treats each node as a step, whether a prompt, a generation, an edit, or an output.

What works: Workflows include If-Else branching, a Prompt Builder, batching through Group Assets, an LLM node, and custom-trained models that run as nodes. Any workflow can publish as a no-node app for a team, and workflows export as JSON. Starter is $15 a month, Pro is $45, and Max is $75, with custom model training starting at Pro.

What doesn't: Starter is a single-user workspace, and the free plan's outputs are for personal and evaluation use only.

Best for: Game and asset studios with their own trained models.
