Orca vs WebBrain: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Orca and WebBrain — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
O
Orca
Stably AI
Desktop AI orchestrator that runs Codex, Claude Code, OpenCode, and Pi side by side in parallel git worktrees, all tracked in one place.
Key features
- Parallel Agent Worktrees: Fan one prompt across up to five agents, each in its own isolated git worktree — compare results and merge the winner.
- Multi-Agent Support: Run Codex, Claude Code, OpenCode, and Pi side by side, all tracked in one unified interface.
- Mobile Companion App: Monitor and steer your agents from iOS or Android — get notified when an agent finishes and send follow-ups from anywhere.
- Ghostty-Class Terminals: WebGL-rendered terminal splits with infinite panes and scrollback that survives restarts.
- Design Mode Browser: Click any UI element in the embedded Chromium window to send its HTML, CSS, and a cropped screenshot straight into your agent's prompt.
- Cross-Platform Desktop: Native builds for macOS, Windows, and Linux so the orchestrator runs alongside your existing dev environment.
- Unified Prompt & History Tracking: Every prompt, tool call, and terminal action across all agents is captured in one place for easy review.
- Steer from Anywhere: Follow-up prompts from the mobile companion keep long-running agent runs moving even when you step away from the desk.
Best for
- Prompt Bake-Off: Send the same feature request to Codex, Claude Code, and OpenCode simultaneously and merge whichever branch wins.
- Long-Running Refactors: Kick off multi-hour agent runs in isolated worktrees and check in from your phone as they progress.
- Design-to-Code Handoff: Click a live UI element in Design Mode and hand its markup and a screenshot to the agent for pixel-accurate implementation.
- Parallel Bug Reproduction: Try multiple diagnostic approaches at once — each agent operates on its own worktree without collision.
- Terminal-Heavy Workflows: Use Ghostty-class terminal splits to keep build watchers, servers, and agent output visible side by side.
- Team Handoffs: Track every agent action in one place so the next engineer can pick up context without replaying a chat log.

WebBrain
Emre Sokullu
Free, open-source browser AI agent for Chrome, Firefox, and Edge that reads pages, extracts data, and automates tasks with any LLM.
Key features
- Page Understanding: Reads and comprehends any web page, PDF, article, doc, or dashboard and answers questions from the current page content on the spot.
- Full Browser Agent: Clicks, types, scrolls, navigates, and interacts with pages on your behalf to automate repetitive tasks from natural-language instructions.
- Read-Only Ask Mode by Default: Starts safe — asks before any consequential action, with stricter rules for sensitive fields, to defend against hijacked pages.
- Multi-Provider LLM: Works with local llama.cpp, OpenAI, Anthropic Claude, and OpenRouter so you can pick the model or run fully offline.
- Dedicated Vision Model: Pairs a fast text-only planning model with a separate vision-capable model for screenshots — cheaper and faster than a single multimodal model.
- Data Extraction: Pulls structured data (tables, lists, links, form contents) out of any page and can export product catalogs, search results, or PDF content.
- Smart Context Management: Automatically trims conversation history and limits tool output to prevent token overflow during long sessions.
- Optional Profile Auto-fill: Local plaintext bio (name, work email, company, throwaway password) lets the agent breeze through low-stakes signup forms; off by default, stored locally.
Best for
- Research Summaries: Open a long article, doc, or PDF and ask WebBrain to summarize or answer specific questions grounded in that page.
- Form Auto-fill: Have the agent complete government, tax, or signup forms by recalling saved profile fields — then review before submit.
- Web Scraping Without Code: Extract product catalogs, price lists, or search results from any page into a clean structured list.
- Offline / Private Browsing AI: Run entirely on-device with llama.cpp to keep sensitive pages, credentials, or client data off the cloud.
- Dev Workflow Assist: Inspect a localhost preview, propose CSS or code changes, and iterate on your own site from the sidebar.
- Video / File Downloads: Locate and save streaming media or attachments from a page you're viewing.
- Self-Hosted Corporate AI Browser: IT teams deploy WebBrain to give employees a browser agent that never sends data to a third-party vendor.
