# Kilo Code alternatives

> Source: https://theagentsindex.com/kilo-code/alternatives (curated, quality-gated, re-verified)

A buyer comparing alternatives to Kilo Code is making two implicit choices: do they want to stay open-source and BYOK, and which surface — VS Code extension, terminal, full IDE, or cloud sandbox — they want the agent to live in. Kilo Code's specific shape, a free extension running across VS Code, JetBrains, CLI and Cloud with a 0%-markup gateway to 500+ models, narrows the genuine alternatives to tools that match at least one of those criteria. Eight entries below, ranked by closeness of substitute, not by feature count.

| # | Name | What it is | Why it's here | Pricing | API |
| --- | --- | --- | --- | --- | --- |
| 1 | [Cline](https://theagentsindex.com/cline.md) | Open-source coding agent for IDEs, terminal and CI, running on any model provider or your own keys. | Cline is the closest substitute on capability: free under Apache-2.0, BYO key, runs in your editor and terminal, and supports 100+ models through Cline's hosted pay-as-you-go option — but it adds ClinePass at $9.99/month for flat-rate open-model access, which Kilo Code does not. | Free | Yes |
| 2 | [OpenCode](https://theagentsindex.com/opencode.md) | Open source AI coding agent for the terminal, IDE and desktop, running any model provider | OpenCode is the MIT-licensed counterpart: terminal, desktop and IDE, 75+ providers, plus a tested model marketplace behind the routing decisions — and OpenCode Go at $10/month absorbs the inference markup the way Kilo Code's gateway does, so the trade-off is governance (Go plan) versus breadth (500+ providers). | Free | Yes |
| 3 | [goose](https://theagentsindex.com/goose.md) | Open source AI agent that runs locally as a desktop app, CLI and API | Goose is the Linux Foundation-backed open-coding-agent with a desktop app, a CLI and 70+ MCP extensions, sitting closer to enterprise procurement than the others on this list — the pick if you want a vendor-neutral steward rather than an independent maintainer. | Free (self-hosted) | Yes |
| 4 | [Aider](https://theagentsindex.com/aider.md) | Open-source terminal pair programmer that edits files in your local git repo and commits each change. | Aider is the terminal-only original: free under Apache 2.0, no IDE integration at all, and 14 LLM providers — which makes it the right answer for a developer who wants a coding agent without an editor surface and does not need VS Code or JetBrains. | Free (Apache 2.0) / forever | No |
| 5 | [Claude Code](https://theagentsindex.com/claude-code.md) | Anthropic's agentic coding tool for the terminal, IDEs, desktop, web, CI and Slack | Claude Code is Anthropic's terminal-native agent with full-repository context, $17/month on Pro — more opinionated than Kilo Code about which models it runs (Anthropic first), with no open-source codebase to inspect, so the trade-off is reasoning quality against the BYOK breadth Kilo Code gives you. | Free | Yes |
| 6 | [Cursor](https://theagentsindex.com/cursor.md) | AI coding agent in a desktop editor, CLI, web and cloud VMs | Cursor is the agentic IDE: a VS Code fork with a coding agent that reads, plans and edits across your whole codebase, free Hobby tier and Pro at $20/month — which is the right answer if you want a full editor bundled with the agent rather than a Kilo Code extension on top of an editor you already use. | Free | Yes |
| 7 | [Codex CLI](https://theagentsindex.com/codex-cli.md) | OpenAI's terminal client for Codex: inspect, edit and run a local repository from the command line. | OpenAI's Codex CLI is Apache-2.0 and ships free with any ChatGPT plan — the right pick if your team is already paying for ChatGPT and you want a terminal agent with no separate inference bill, traded against being limited to OpenAI's model lineup instead of Kilo Code's 500-provider gateway. | Free | Yes |
| 8 | [Devin](https://theagentsindex.com/devin.md) | Cognition's autonomous AI software engineer: takes a ticket, works in its own workspace, opens a pull request. | Devin is Cognition's autonomous cloud agent at $20/month Pro: assign a task through Slack, CLI or the web app and it plans, edits, tests and opens a PR inside its own sandbox — the hosted alternative for teams that want the agent to own the whole ticket rather than collaborate inside their editor. | Free | Yes |

## Methodology

Held the buyer job constant: a coding agent that reads, edits and ships code, regardless of whether the agent is an editor extension, a terminal tool, a full IDE, or a hosted cloud service. Excluded dedicated code-review agents (CodeRabbit, Augment Code) and prompt-to-app builders (Bolt.new, Replit Agent) because they sit adjacent to Kilo Code's job rather than on the same shelf. Ranked eight entries by closeness of substitute: open-source plus BYOK plus multi-model first (Cline, OpenCode), then the Linux Foundation-backed option (Goose), then terminal-native big-tech agents (Aider, Claude Code, Codex CLI), then IDE-bundled (Cursor), and finally the hosted cloud alternative (Devin). Prices are the entry tier published on each vendor's own site; "free" means the core product is free with the user paying only model inference costs.
