Cline takes a goal, proposes a multi-step plan, and then executes it by editing files, running commands, and validating changes.
The extension runs client-side and connects to models via API keys you provide, including Claude, GPT, Gemini, local models, and more.
Cline can run commands in your terminal, inspect command output, and optionally open a browser to check your app or documentation while working on tasks.
Cline integrates with the Model Context Protocol to use external tools and services as part of its workflows.
The full source code is available on GitHub, and the architecture emphasizes client-side control over secrets and model calls.
Developers can ask Cline to migrate frameworks, introduce new modules, or implement features, and let it plan and execute multi-file edits with human oversight.
Cline can run tests, read logs, and update code across multiple files, making it suitable for debugging issues that span several components.
For large monorepos, Cline’s planning and tool-use make it better suited than pure autocomplete for tasks like major refactors, scaffolding, or API migrations.
Teams can experiment with different LLM providers and local deployment options without being tied to a single SaaS vendor, thanks to Cline’s model-agnostic design.

Devin is an autonomous AI software engineer from Cognition Labs. Rather than focusing only on autocomplete or snippets, Devin takes on full software tasks: it can plan work, set up environments, browse documentation, write and run code, and iterate until tests pass. Devin can collaborate with human engineers by reporting progress, asking for clarification, and integrating into existing workflows. It is aimed at serious engineering teams that want an AI agent to handle substantial portions of delivery work.
Replit Agent is Replit�s AI-powered development agent that can plan, generate, debug, and deploy full-stack applications directly in the Replit environment using natural language instructions. It is integrated into Replit�s browser-based IDE and hosted platform, allowing users to go from idea to running app quickly without managing servers. The agent can handle tasks like building UIs, wiring backends, configuring databases, and fixing errors, while users guide it via chat. Replit bundles Agent access into its paid Core and Teams plans, with a trial in the free Starter tier and usage tied to Replit credits and plan limits.
Smol Developer is an open‑source agentic coding library that acts like a junior developer for your projects. Given a product spec, it can scaffold an entire codebase, plan files, generate implementations, and help debug and iterate. Smol focuses on whole‑program synthesis rather than line‑by‑line completion, making it a powerful building block for custom internal tools or experimental workflows where AI owns more of the scaffolding work.
