Open source Apache 2.0 coding agent runtime across VS Code, JetBrains, CLI and an embeddable SDK, with Plan and Act modes, per action approval, an MCP marketplace, browser control and any model on your own key or weights.

Cline is an open-source autonomous coding agent that lives inside the tools developers already use rather than asking them to switch editors. Released originally as Claude Dev and distributed under the Apache 2.0 license, it runs as a sidebar in VS Code, as a plugin for JetBrains IDEs, as a terminal CLI, and as an embeddable runtime, all powered by the same engine. Unlike an autocomplete tool that suggests the next line, Cline is a true agent: it reads a codebase, plans an approach, creates and edits files, runs terminal commands, and can even drive a real browser to test the result, iterating through an implement-test-fix loop until the task is done.

Control and transparency are central to how it works. Cline splits work into Plan and Act modes: in Plan mode it explores the code and lays out a strategy, asking clarifying questions, and in Act mode it carries that plan out. By default every file edit and terminal command is presented for your approval before it runs, so you see exactly what will change, though you can switch on auto-approve to let it run unattended. Coordinated multi-file edits come with diffs, checkpoints, and one-click undo at each step.

Because it is model-agnostic and bring-your-own-key, Cline works with every major provider, including Anthropic, OpenAI, and Google, as well as local models through Ollama, so teams can keep sensitive code on their own infrastructure, including air-gapped deployments. There is no Cline subscription; you pay only for the inference you use. A .clinerules file in a repository teaches the agent a project's standards and conventions, and first-class Model Context Protocol support lets it reach databases, API docs, issue trackers, and monitoring tools.

Beyond a single editor session, Cline can run headlessly in CI pipelines and on cron schedules, coordinate multiple agents where a lead delegates to specialists, and be driven from chat tools like Slack and Linear. It is aimed at developers who want agentic capability without giving up their existing setup, their choice of model, or control over their data.

Integrations

First class MCP support with an in-product Marketplace offering one click install and automatic configuration across filesystem, database, Airtable, Azure DevOps, Discord, browser and documentation servers, plus GitHub install, remote server connection and a documented server development protocol. The agent executes terminal commands and reacts to output live, drives a real Chromium instance through browser_action, and connects to Slack, Discord, Telegram and Linear for conversational invocation and to GitHub Actions, GitLab or any pipeline for headless runs. A Node.js SDK registers custom tools and lifecycle hooks on the same engine, and ACP connects third party editors.

In practice

You want a real coding agent but refuse to abandon your customized VS Code setup. Cline installs as a sidebar extension, reading your code, editing files, and running commands in place without migrating to a new editor.

Your code can't leave your network, so a cloud-only agent is a non-starter. Cline is bring-your-own-key and works with local models through Ollama, so it can run fully on your own infrastructure.

You want to see exactly what an agent will change before it touches anything. Cline's Plan mode lays out a strategy first, and every file edit and command waits for your approval, with diffs and one-click undo.

Integrations & Tool Calling Full

The agent runs terminal commands and reacts to their output, calls MCP servers the developer adds, drives a Chromium browser, and connects to Slack, Discord, Telegram and Linear for conversation and to GitHub Actions and GitLab for headless runs.

Sourcecline.bot and docs.cline.bot (MCP overview)read 2026-09-29

Workflow Orchestration Full

Multi agent teams let coordinator agents delegate to specialist agents with their own tools, agent teams coordinate from the CLI, and a Kanban board runs several coding agents in parallel in isolated git worktrees.

Sourcecline.bot and docs.cline.bot (Kanban, agent teams)read 2026-09-29

Knowledge Grounding & RAG Partial

The agent reads the project as it works, with.clinerules for standards, @git and @terminal mentions and MCP servers for outside sources. Cline states it avoids indexing the customer's code, so context is assembled per run and no persistent index, graph or embeddings layer exists.

Sourcedocs.cline.bot enterprise overview and cline.botread 2026-09-29

Human Oversight & Guardrails Full

Plan mode aligns on a strategy before execution, and in Act mode the developer approves every step by default, with auto approve an opt in that can be scoped per action type, plus diffs, checkpoints and one click undo.

Security, Identity & Governance Partial

Enterprise adds SSO, role based access control with Member, Admin and Owner roles, remote configuration, limits on inference providers, MCP controls and authentication logs, and the client side architecture keeps code in the customer's environment. No SOC 2 or other attestation is named on the enterprise pages.

Sourcedocs.cline.bot enterprise overview, cline.bot/enterprise and cline.bot/pricingread 2026-09-29

Observability & Auditability Full

OpenTelemetry export sends per action events to the customer's Datadog, Grafana or Splunk: task.tool_used with tool name, success, duration and whether it was auto approved, MCP tool calls with server and status, terminal executions, and accepted and rejected edits, alongside task lifecycle and token events.

Memory & State Persistence Partial

Checkpoints capture workspace state during a task for rollback, and the Memory Bank is a documented method the user sets up through custom instructions, with Cline updating markdown files it reads across sessions. The Memory Bank is not a built in memory layer and states no lifetime or purge path, and rules and mode preferences are instructions and settings.

Deployment & Data Residency Full

Enterprise runs in the customer's VPC, on premises or air gapped, the client side architecture sends inference straight to the customer's own Bedrock, Vertex, Azure OpenAI or local models without passing through Cline's servers, and the open source agent runs in the developer's editor or terminal.

Prebuilt Agents, Templates & Packs Full

An MCP Marketplace ships in the open source product as a catalog of servers installable in one click, and modular Skills package instruction sets for specific tasks.

Triggers & Channel Coverage Full

The CLI runs agents on cron schedules through its hub, unattended and persisting across restarts, for work such as daily summaries and dependency checks, and agents also run headlessly in CI and answer from Slack, Discord, Telegram and Linear, so work reaches the agent without a person starting it.

Model Flexibility & Routing Full

Works with every major provider on the customer's own key, Claude, GPT, Gemini, local Ollama or LM Studio and any OpenAI compatible endpoint, with enterprise connections to Bedrock, Vertex and Azure OpenAI and admin limits on which providers teams may use.

APIs, SDKs & MCP Extensibility Full

The Cline SDK publishes TypeScript packages for embedding Cline's agent runtime in other applications, and the CLI runs headless for scripts and pipelines.

Testing, Debugging & Optimization Partial

The agent makes linter aware fixes, runs tests and checks UI work in a real browser, and checkpoints let a failed attempt be rolled back; these check the agent's own output, and no harness to evaluate or regression test agent behavior is documented.

Browser & Computer Use Full

A browser action tool drives a Chromium browser the agent navigates, clicks, types and scrolls in, reading a screenshot and console logs after each action, and remote browser support reuses an existing Chrome session's logins.

Pricing

Free and open source; model usage at cost or on your own key

usage

Free tier

What is public

The open source plan is free with no subscriptions or seat fees; model inference is bought from Cline at cost or used on the developer's own key. Enterprise pricing is custom.

Billing mechanics

Usage based only: the cost is model inference, either paid to the developer's own provider or bought as Cline inference credits at cost; Enterprise is contracted through sales.

Variable cost rationale

Free extension, but agentic runs against a frontier model via your own key are pay-as-you-go and can add up with heavy use.

Sales call required

No, self serve available

Free / trial

Free (OSS self-host)

Key ambiguities

Spend is driven by model choice and usage volume rather than a Cline subscription; Enterprise terms are quoted by sales.

Missing data

Enterprise pricing is not published.
