ARBR vs Photopea: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of ARBR and Photopea — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
ARBR
Gyde & Domkundwar Foundation
Open-source, MIT-licensed AI gateway and control plane that routes, governs and observes every LLM request behind one OpenAI-compatible endpoint.
Key features
- OpenAI-Compatible Routing: A single drop-in endpoint over every major provider, with rules, difficulty-aware selection, cost guardrails and automatic fallback choosing the model per request.
- In-Path Governance: Budgets, rate limits, output guardrails, prompt-injection checks and kill switches enforce policy before inference rather than auditing it afterwards.
- Structured Observability: Cost, latency, tokens and routing decisions are emitted as structured events attributed by application, team, model and user, viewable in local dashboards or exported to OpenTelemetry backends such as Datadog, Grafana and Prometheus.
- LLM-Judge Evaluation: A sample of live traffic is scored for quality so requests can be routed to the cheapest model that provably clears the bar, rather than optimising on price alone.
- Safe Model Deployment: Canary and shadow new models against real traffic with regression gates that block promotion until evaluations pass, plus instant rollback.
- Broad Provider Coverage: One layer over Anthropic, OpenAI, Google Gemini, Amazon Bedrock, Azure OpenAI, Vertex AI, Groq, DeepSeek, Moonshot, xAI and Mistral, plus LiteLLM and NVIDIA NIM, with pricing and benchmark data for over 3,000 models.
- Drop-In SDK Compatibility: Change only the base URL and existing OpenAI SDKs, agent frameworks and chat UIs keep working, gaining streaming chat completions, embeddings, a realtime voice proxy and JavaScript and Python SDKs.
- Self-Hosted and MIT Licensed: The full control plane runs inside your own infrastructure under an MIT licence, with a hosted option available for teams that do not want to operate it.
Best for
- LLM Cost Reduction: Route summarisation and extraction traffic to cheap small models while reserving frontier models for analysis, cutting spend without hand-editing every call site.
- AI Spend Attribution: Give finance and engineering a per-application, per-team and per-user breakdown of token spend so AI budgets can be owned by the groups that generate them.
- Enterprise AI Governance: Enforce departmental budgets, rate limits and kill switches in the request path so a runaway agent cannot exhaust a quarter's inference budget.
- Provider Risk Mitigation: Keep applications provider-neutral behind one endpoint with automatic fallback, so a single vendor outage or price change does not require a code change.
- Model Migration Testing: Shadow or canary a newly released model against production traffic and let regression gates decide whether it is promoted.
- Prompt-Injection Defence: Apply output guardrails and prompt-injection checks centrally for every application instead of reimplementing them per service.
Photopea
Photopea
Browser-based PSD-compatible online photo and graphics editor for raster and vector files, free to use in your browser.
Key features
- PSD/Vector/Sketch Support: Opens and exports popular industry file formats (PSD, AI, Sketch) so users can work with files from Photoshop and other design tools without conversion.
- Layer-Based Editing: Provides layers, masks, blending modes and layer groups to enable non-destructive, multi-layer composition workflows comparable to desktop editors.
- Core Photo Tools and Filters: Includes selection tools, crop/resize, adjustment layers, retouching tools, filters and effects for comprehensive photo editing and corrections.
- Text and Vector Tools: Offers text layers, shape and pen tools for vector artwork and layout work alongside raster editing in the same project.
- No-Install Browser Operation: Runs entirely in modern web browsers, allowing immediate access across platforms (Windows, macOS, Linux) without installation.
- File Import/Export and Asset Handling: Enables importing images from local files or URLs and exporting to various raster/vector formats for web and print use.
- Integration & Automation Options: Community projects and GitHub references show usage as an embeddable editor, Electron desktop wrappers, and headless/API-style automation options.
- Community & Support Channels: Maintains a public GitHub repository for bug reports, feature requests, and discussions to gather user feedback and improvements.
- Full-featured in-browser image editor with tools for selection, painting, retouching, and compositing
- Support for professional file formats including PSD, AI, and Sketch (import/export)
- Standard image format support (PNG, JPG) and direct editing of uploaded images
- Layer-based editing with text, filters, effects, cropping and resizing
- Runs entirely in the browser with no installation required; can be wrapped in Electron for desktop use
- Community-facing GitHub repository for bug reports, feature requests and discussions
- Integrations and community projects (Obsidian plugin, Puter integration, Electron wrapper, headless/automation projects)
Best for
- Editing and retouching photos in the browser without installing desktop software, for quick fixes or detailed photo workflows.
- Opening and modifying PSD and Sketch files when a user needs to view or edit designs but doesn't have Photoshop or Sketch installed.
- Cross-platform graphic design work on Windows, macOS, or Linux via the browser or Electron wrappers to provide native-like access.
- Embedding or integrating the editor into other apps or workflows (plugins, Obsidian integration, Electron wrappers) to enable inline image editing.
- Automating image workflows by using community headless/automation wrappers to perform batch edits or scripted manipulations.
- Creating mockups, marketing assets, or social media images quickly using layer-based layouts, text, and export to common image formats.
- Providing an accessible tool for students and educators to teach design and image-editing concepts using a free, zero-install editor.
- Edit and retouch photos directly in the browser without installing native software
- Open, modify and export PSD/AI/Sketch files for cross-tool workflow compatibility
- Embed or wrap Photopea into desktop or web apps via Electron wrappers or integration plugins
- Automate image-editing workflows using community headless/automation projects
- Use within note-taking or web platforms (e.g., Obsidian, Puter) to enable inline image editing
