PlugNode vs InvokeAI

InvokeAI is the polished open-source Stable Diffusion canvas: Apache-2.0, self-host, deep SD ecosystem fluency. Adobe acquired the company in October 2025 and shut down the hosted SaaS. PlugNode is the maintained hosted alternative (multi-model, multi-provider) with flows published as signed webhook APIs.

TL;DR

InvokeAI is still the best self-hosted Stable Diffusion canvas in the open-source world. PlugNode is the hosted, multi-provider answer for teams that liked the Indie / Professional / Enterprise tiers Adobe sunset on October 31, 2025.

InvokeAI built the most polished node-based canvas in the Stable Diffusion ecosystem: unified inpainting / outpainting / regional prompting on a layered canvas, deep model management for SD 1.5 through FLUX.2 Klein and Z-Image, plus a Form Builder that turns node graphs into operator-friendly UIs. Then Adobe acquired the company on October 20, 2025, and the hosted SaaS (Indie / Professional / Enterprise) was retired on October 31, 2025. The Apache-2.0 OSS continues (27K+ GitHub stars, 24K+ Discord), but anyone who depended on the managed cloud product now has to self-install or migrate. PlugNode is built for the migration path: hosted by default, multi-provider (image, video, audio, LLM), with every flow publishable as a signed HTTP endpoint with webhook delivery, versioning, and rollback.

Side by side

PlugNode
InvokeAI
Hosted product status
Maintained hosted SaaS with workspace billing, run history, and BuildBase-backed auth.
Hosted Indie / Professional / Enterprise tiers shut down October 31, 2025 after Adobe acquisition. Only the open-source self-install remains.
API publishing
Every flow becomes a signed HTTP endpoint with on_complete / on_error webhooks and mid-flow respond-to-webhook.
No public webhook API. GitHub Issue #6581 ("Is there an API?") was closed as not planned. The internal FastAPI surface powers the local Web UI only.
Media coverage
Text, image, video, and audio nodes with a generic HTTP node for any other provider.
Image generation only. No first-class video, audio, or LLM nodes in the Workflow Editor.
Model providers
Bring your own keys for Gemini, OpenAI, ElevenLabs, plus arbitrary providers via the HTTP node.
Locally installed weights only: Stable Diffusion family, FLUX, Z-Image. No BYOK for hosted providers like OpenAI, Gemini, Runway, or Veo.

Which should you pick?

Pick PlugNode if …

Teams that need a maintained hosted canvas (multi-model, multi-provider) to ship image, video, audio, and LLM pipelines as signed APIs with versioning and BYOK pricing.

Pick InvokeAI if …

Power users and studios who want a self-hosted, open-source Stable Diffusion canvas with deep model management, layered inpainting, and full IP control over local weights.

Frequently asked questions

Is InvokeAI still available?
The Apache-2.0 open-source Community Edition is still actively developed (v6.12.0 shipped March 2026, 27K+ GitHub stars). However, Adobe acquired Invoke AI, Inc. on October 20, 2025, and the hosted SaaS (Indie / Professional / Enterprise tiers) was sunset on October 31, 2025. There is no managed cloud version of Invoke anymore, only self-install.
Does InvokeAI have a public API for triggering workflows?
No. GitHub Issue #6581 ("Is there an API?") was closed as not planned. The FastAPI backend that powers the local Web UI is not a documented public integration target: no signed-secret webhook, no rate-limited public trigger URL, and no on_complete / on_error delivery. PlugNode publishes any flow as a signed HTTP endpoint with webhook delivery, run history, and versioned rollback.
Can InvokeAI generate video or audio?
No. The Workflow Editor is built around diffusion-image generation pipelines: primitives, model references (MainModel, LoRA, VAE, ControlNet), and schedulers. There are no first-class video, audio, or LLM nodes. PlugNode covers text, image, video, and audio with native provider integrations plus a generic HTTP node for any other API.
Can I use OpenAI, Gemini, or Runway models with InvokeAI?
No. Generation runs against locally installed model weights (Stable Diffusion family, FLUX, Z-Image). There is no documented BYOK path for hosted providers like OpenAI, Anthropic, Gemini, Runway, ElevenLabs, fal, or Replicate. PlugNode supports BYOK for Gemini, OpenAI, and ElevenLabs natively, and an HTTP node for anything else.

Honest recommendation

Want a self-hosted, open-source Stable Diffusion canvas with deep model management and full IP control? InvokeAI Community Edition. Need a maintained hosted SaaS to ship multi-model image, video, audio, and LLM pipelines as signed APIs? PlugNode, and the natural migration target if you depended on Invoke’s sunset hosted tiers.
