Cline is known for being open source, supporting bring-your-own-key, and offering model freedom, but it is not the only option. In 2026, Cursor has made the IDE experience more complete, Claude Code has matured as a terminal agent, and Roo Code has reached the end of its maintenance cycle. Whether to switch, and to what, depends on your workflow and governance model rather than on a single demo.
This article compares the options across workflow, model choice, cost model, IDE support, and team control, and provides a migration checklist you can follow step by step. Features and billing change quickly; refer to each vendor's official documentation and to model pricing for specifics.

1. Decide first: change the tool or change the connection
Many teams say they want to "replace Cline," but the real problem is that models are too expensive, keys are hard to manage, or access is unstable. Those are access-layer issues that a unified gateway can solve without migrating the workflow.
A genuine tool change is usually driven by editor experience, terminal automation, team permissions, or a unique feature. Write down which category the pain point belongs to before deciding the scope. Otherwise, after the switch, the old problem will reappear in a new form.
Roo Code is a variable that needs a separate explanation. It originated from Cline, but its main repository was archived in May 2026, and community forks continue under names such as ZooCode. Teams treating Roo Code as long-term infrastructure should make "whether the fork is actively maintained" a hard requirement.
2. Positioning of the four options
Cline: an open-source editor and terminal agent, available as a VS Code extension, JetBrains plugin, CLI, and desktop app. Core capabilities include Plan/Act dual modes, checkpoints, MCP tools, and rules files. Model access supports bring-your-own-key, account usage billing, an optional subscription, and OpenAI-compatible endpoints. The advantage is transparency and freedom; the cost is that keys and quotas are your responsibility to govern.
Cursor: an AI IDE built around the editor, where completion, chat, and agent collaboration all live in one interface. Billing is mainly subscription plus usage, and different plans expose different models. It suits developers who spend most of the day inside the editor; if the workflow is primarily terminal, CI, or batch processing, the advantage shrinks. Whether BYOK is supported, and to what extent, is governed by the official documentation.
Claude Code: a terminal-first coding agent that also provides IDE extensions. It centers on Anthropic models by default, can use a subscription or API, and supports connecting to a compatible gateway through ANTHROPIC_BASE_URL. Its strengths are long-running tasks, tool calling, and repository-level changes, with managed settings and permission modes on the team side.
Roo Code / ZooCode: Roo Code was once a popular fork of Cline, adding multi-mode and multi-agent ideas. After the main repository was archived, new projects are better off evaluating Cline itself or community forks such as ZooCode. Before migrating an old project, confirm whether the plugins, rules, and MCP configuration it depends on are still maintained.
3. Comparison across five dimensions
| Dimension | Cline | Cursor | Claude Code | Roo Code / ZooCode |
|---|---|---|---|---|
| Workflow | Plan/Act, editor and terminal | In-IDE completion, chat, agent | Terminal-first continuous agent | Multi-mode, multi-agent ideas |
| Model choice | BYOK across providers, OpenAI-compatible | Mainly the model catalog in each plan | Mainly Anthropic, can use a gateway | BYOK across providers |
| Cost model | Mostly pay-as-you-go, plus account usage and subscription | Subscription plus usage | Subscription or pay-as-you-go API | Mostly pay-as-you-go |
| IDE support | VS Code, JetBrains, CLI, desktop | Its own editor | Terminal and IDE extensions | VS Code family |
| Team control | Relies on a self-built gateway and key management | Team backend and policies | Managed settings, permissions, quotas | Relies on self-built governance |
| Maintenance status | Active | Active | Active | Main repository archived; check the fork |
The table describes form, not which tool is stronger. What really matters is where your team spends the most time each day, which tasks must be handed to an agent for continuous execution, and who can tolerate multiple bills.
4. Choose by scenario
| Scenario | Better fit | Reason |
|---|---|---|
| Need BYOK, multiple models, transparent cost | Cline | Open source, BYOK, broad provider choice |
| Do not want to leave the editor; value completion | Cursor | Unified in-IDE experience, quick to learn |
| Terminal-first, long refactors and test runs | Claude Code | Complete toolchain, continuous agent execution |
| Existing Roo Code workflow | Cline or ZooCode | Verify rules, modes, and plugin compatibility first |
| Team needs unified keys, billing, and quotas | Cline / Claude Code with a gateway | Gateway provides one entry point, usage, and limits |
| Strict compliance, intranet, or data residency | Evaluate case by case | Check data flow, deployment model, and audit capability first |
5. Differences in cost models
Cline and Roo Code are mainly BYOK pay-as-you-go, with bills that fluctuate with tokens. Cursor is mainly subscription plus usage, with predictable bills constrained by plan quota. Claude Code can use either a subscription or an API. None of the three models is inherently superior; the key questions are whether usage is stable, whether multiple models are needed, and whether the team can accept multiple bills.
Coding agents usually consume far more tokens than chat because they resend context every round. When evaluating a migration, record input, output, cache hits, and retries from real tasks, then calculate against model pricing. Do not compare nominal unit prices alone.
6. Configuration example: unify access through a compatible endpoint
If the goal of migration is only to unify the model entry point, verify the gateway's OpenAI-compatible interface first, then choose "OpenAI Compatible" in Cline and enter the Base URL, API key, and Model ID:
curl https://ai.zhongshangqihang.com/v1/chat/completions \
-H "Authorization: Bearer $OPENAI_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"your-model-id","messages":[{"role":"user","content":"ping"}]}'
Cline's OpenAI-compatible configuration needs four items: select OpenAI Compatible as the provider, enter the Base URL, enter the API key, and enter the exact Model ID. Whether the Base URL includes /v1 depends on the provider; an incorrect value usually shows up as a 404 or a missing model. Claude Code uses the Anthropic-compatible entry point, so do not mix the two sets of environment variables.
7. Migration checklist
- Inventory the workflow: how much time goes to terminal, IDE, completion, agent, and CI.
- List model dependencies: which tasks require a specific model, and which can be downgraded.
- Confirm the protocol: Anthropic Messages or OpenAI Chat Completions.
- Choose the access method: subscription, BYOK, or a unified gateway.
- Migrate rules files:
.clinerules,.cursor/rules,CLAUDE.md, andAGENTS.mdshould not be copied verbatim. - Retest MCP and tools: paths, permissions, and timeouts may all change.
- Pilot on one repository for one to two weeks and record completion and rework rates.
- Compare costs: include retries, long context, and failed requests.
- Then roll out to the team: one key per person, project limits, and retained logs.
- Keep a rollback path: do not delete the old tool and old configuration for at least one cycle.
8. Four things most often overlooked in migration
First, rules files are not a universal format. Cline reads .clinerules/ or .cline/rules/ and also recognizes files such as AGENTS.md and .cursorrules; Cursor and Claude Code each have their own context files. Copying verbatim often does not work. Split project conventions, commands, and prohibited areas into the format each tool supports.
Second, MCP configuration must be retested. After changing tools, the working directory, environment variables, and sandbox boundaries may all change, and a tool that used to work may no longer work.
Third, context cost changes. Different tools have different file-reading strategies, and the same task may consume more or fewer tokens. Compare real bills during the pilot.
Fourth, team governance cannot be added later. Members, keys, quotas, and logs should be planned before rollout; otherwise, when something goes wrong, it is difficult to trace it to a person.
FAQ
What is the relationship between Cline and Roo Code?
Roo Code originated from Cline, initially developed as a fork, and later added capabilities such as multi-mode and multi-agent operation. Their configuration formats are similar but not fully interchangeable.
Can Roo Code still be used after the repository was archived?
Installed versions can still run, but new features, fixes, and security updates depend on fork maintenance. The main repository was archived in May 2026, and community forks continue under names such as ZooCode; new projects should prioritize versions that are still maintained.
Does migrating from Cline to Cursor require reconfiguring models?
Usually yes. Cursor mainly relies on the model catalog included in each plan, and BYOK support is governed by its official documentation. Confirm that the target model is available before migrating.
Does the API key need to change after switching tools?
Not necessarily. If the new tool supports the same protocol and endpoint, you can keep using it. When the protocol differs, the gateway needs to provide both Anthropic- and OpenAI-compatible entry points, or you need separate keys.
Should a team switch everything at once?
Not recommended. Let a small team pilot first and complete a full iteration before deciding whether to roll it out. Keep the old tool for at least one cycle to make rollback easy.
Next steps
If the issue is only the access method, start by signing up for ZSQH AI Gateway and run one repository with a test key. If a tool change is genuinely needed, verify each item against the checklist above. Models and billing are governed by model pricing.
