Kilo Code and Cline are cousins. Cline came first; Roo Code forked it; then Kilo Code forked both and merged them. So the honest framing isn't "which is better" but "how much agent do you want." Cline is the lean, transparent original with 60k+ GitHub stars and a strict approve-every-action loop. Kilo Code is the superset — same lineage, plus Orchestrator mode, subagents, a Memory Bank and JetBrains support.
The short answer
Choose Kilo Code if you want the deepest feature set, work on big multi-file tasks, or are migrating off the archived Roo Code. Choose Cline if you want a smaller, more auditable agent with a longer track record and a gentler learning curve. Both are free and BYOK, so trying each costs only tokens.
Side-by-side comparison
| Kilo Code | Cline | |
|---|---|---|
| License | Open source (Apache 2.0) | Open source (Apache 2.0) |
| IDEs | VS Code, JetBrains, CLI, Cloud | VS Code (JetBrains in progress) |
| Execution model | Modes + Orchestrator routing | Plan/Act, approve every action |
| Parallel agents | Yes — subagents via git worktrees | No — single agent |
| Memory / context | Memory Bank persists architecture | Per-session context |
| Models | 500+ via Gateway, BYOK, local | BYOK, OpenRouter, local |
| MCP support | Yes | Yes (can build MCP servers) |
| Pricing | Free tool; Teams $15/user/mo | Free tool; Teams plan |
| Maturity | Fast-growing, broad surface | Established, 60k+ stars |
Where Kilo Code wins
Kilo's edge is structure at scale. Orchestrator mode decomposes a large request and hands each subtask to a specialist mode — Architect plans, Code writes, Debug fixes — which consistently beats a single agent grinding through everything in one thread. On top of that, subagents run in parallel via git worktrees, so you can have several agents working separate branches without collisions.
It's also broader in reach: JetBrains support, a CLI, cloud agents and a Memory Bank that keeps architectural context between sessions. And with Roo Code archived in May 2026, Kilo is the natural home for Roo users because it preserves the custom-mode workflow and a migration path. Our Kilo Code review digs into how those pieces feel day to day.
Where Cline wins
Cline's strength is restraint. Its Plan/Act loop reads your codebase, proposes a step-by-step plan, then executes with your approval at every file edit and command. Nothing happens without you seeing it, which makes it the more auditable of the two — a real advantage for regulated teams and anyone who wants to keep a tight leash on an agent.
That smaller surface is easier to learn and easier to trust. Cline's MCP support is also a standout: it can scaffold, configure and install a new MCP server for you, not just consume existing ones. With 60k+ GitHub stars and a long track record, it's the safer default if you value simplicity. See the full breakdown in our Cline review.
Cost: the same idea, different extras
Both are free tools with a bring-your-own-key model and no markup on tokens, so your real bill is the model you choose — roughly $0.50–$2.00 a session on Claude Sonnet, more for all-day use. Kilo adds a $15/user/month Teams plan and optional prepaid Kilo Pass credits from $19/mo; Cline has its own Teams plan for centralized billing. Neither locks core features behind a paywall. The Kilo Code pricing guide has the full breakdown if cost is your deciding factor.
Which should you pick?
Go with Kilo Code if you want the most capable open-source agent, you regularly tackle large multi-file features, you want JetBrains or parallel subagents, or you're leaving Roo Code. It's the more powerful tool and the one with the most momentum in 2026.
Go with Cline if you prefer a lean, transparent, approve-everything agent with a smaller learning curve and a battle-tested reputation. If you want a fixed monthly bill instead of at-cost tokens entirely, a paid IDE like Cursor is worth a look, and our best AI coding assistants roundup ranks the whole field. Still unsure? Both are free — install each and run the same task through them for an afternoon.
Frequently Asked Questions
Is Kilo Code just a fork of Cline?
Kilo Code forked both Cline and Roo Code and merged them into a superset. It keeps Cline's approval-gated execution, adds Roo's custom modes, and layers on Orchestrator mode, inline autocomplete, a Memory Bank, parallel subagents and JetBrains support. So it's a fork in origin but broader in scope than Cline today.
Which is better for large multi-file tasks, Kilo Code or Cline?
Kilo Code, generally. Its Orchestrator mode decomposes a big task and routes each piece to a specialist mode, and subagents can work in parallel via git worktrees. Cline's plan-then-execute flow is excellent and very auditable, but it runs as a single agent, so heavy multi-file work is where Kilo's structure pulls ahead.
Are Kilo Code and Cline both free?
Yes. Both extensions are free and open source and use a bring-your-own-key model with no markup on tokens. Kilo adds a $15/user/month Teams plan and optional prepaid Kilo Pass credits; Cline has a Teams plan too. Your real cost with either is the model you plug in.
Does Cline have anything Kilo Code doesn't?
Cline's strength is simplicity and a longer track record — 60k+ GitHub stars and a tight, transparent plan-then-execute loop where every action needs approval. Some developers prefer that smaller, more predictable surface over Kilo's larger mode-and-subagent system, especially for auditability.
I'm on Roo Code — should I move to Kilo or Cline?
Kilo Code. Roo Code's original repository was archived in May 2026, and Kilo preserves a Roo migration path plus the custom-mode workflow Roo users are used to. Moving to Kilo keeps your modes and gains active maintenance.
Which should a beginner start with?
Cline is the gentler start — fewer modes, an obvious plan-then-approve loop, and a large community. Once you want Orchestrator mode, subagents, JetBrains support or a Memory Bank, Kilo Code is the natural next step.
