OpenCode vs Windsurf: pricing, features and which to choose

OpenCode is an open source coding agent for terminal, desktop, and IDE workflows. The public site reports more than 215,000 GitHub stars, 950 contributors, 20,000 commits, and more than 16 million developers monthly, figures the company can change. The repository identifies the software as MIT licensed. Current documentation distinguishes OpenCode 1 and OpenCode 2, which share the same command name and cannot coexist under default installation paths. Version 2.1.2 is dated October 21, 2026. OpenCode is best understood as a client and agent layer rather than one hosted assistant. It can inspect repositories, explain code, edit files, run commands, and keep multiple sessions. The MIT license permits commercial modification and distribution subject to its conditions.

A typical workflow starts in a project directory with the opencode command. The documentation describes an /init command that creates an AGENTS.md file for project structure and coding conventions. OpenCode separates a build agent from a plan agent: the build agent can edit files and run commands, while the plan agent is read-only by default and asks before bash commands. Sessions can use LSP integration, provider selection, and a general subagent. Developers can connect OpenAI, Anthropic, Google, xAI, GitHub Copilot, ChatGPT Plus or Pro, local models, OpenCode Zen, or OpenCode Go. The terminal, desktop, and IDE clients support the same provider choice. This workflow is adaptable, although the account, model, quota, and data terms depend on the selected route.

OpenCode's main tradeoff is choice. Provider selection can reduce lock-in, but it also makes billing, privacy, and troubleshooting less predictable than a single-vendor product. The Go privacy table says most listed models do not use prompts for training, while Muse Spark models permit training and Gemini 4 Argon Contributor may use prompts and completions for future Google models. Compared with Claude Code, OpenCode offers local models and a broader provider route. Compared with Cursor, it is more terminal centered and MIT licensed. Compared with Aider, it adds desktop and IDE clients. Pick OpenCode for repository work when provider flexibility matters more than one unified account and bill.

Windsurf was an agent-native code editor made by Cognition. The product launched in November 2024, after the company began as Exafunction in 2021 and rebranded to Codeium in 2022. Codeium became Windsurf as a company in April 2025, and Cognition signed an agreement to acquire the product, intellectual property, trademark, business, and team on July 14, 2025. Cognition described a business with $82 million in annual recurring revenue, more than 350 enterprise customers, and hundreds of thousands of daily active users. On June 2, 2026, Windsurf became Devin Desktop, unifying the editor with Cognition's Devin products while retaining the editor, extensions, workflows, settings, and familiar development experience for existing users.

The workflow combines a VS Code-style editor with extensions, language servers, terminals, Git tools, previews, worktrees, project context, and agent sessions. A developer can open a repository, let the context engine index relevant files, ask an agent to plan a change, review proposed edits, and run commands or tests in the integrated terminal. Tab offers inline suggestions with code jumps and imports, while Command creates or changes code from an inline prompt without premium credits. MCP servers, memories, rules, workflows, skills, and codemaps support larger projects. Agent sessions can run locally, in worktrees, or through Devin Cloud, allowing users to continue editing locally while delegating larger tasks to a cloud agent and reviewing its results from the same desktop workspace.

Quota-based billing is the main limitation because consumption changes with the selected model, task size, complexity, and reasoning requirements, so users seeking a fixed request allowance may find the system difficult to predict. The 2026 transition also changed familiar names from Cascade and Windsurf to Devin Local and Devin Desktop. Cognition's privacy policy says User Content may be used to train, fine-tune, and improve models depending on applicable terms, so teams should review agreements before sending proprietary code. Cursor is the closest editor-focused competitor, GitHub Copilot fits established GitHub and IDE workflows, Tabnine emphasizes enterprise controls, and Replit targets browser-based development. Choose Devin Desktop for local editing, terminals, multiple model providers, and optional Devin Cloud delegation; choose Cursor for a similar AI-first editor or GitHub Copilot for deeper GitHub integration.
