The facts

Kilo Code is an open-source AI coding agent that runs inside VS Code, JetBrains IDEs (IntelliJ, PyCharm, WebStorm), as a CLI, in the cloud, and via Slack. Started as a fork of Roo Code and built by Kilo-Org on $8M in seed funding, Kilo was acquired by Anaconda in July 2026 and continues as an open-source product for individuals, teams, and organizations. It has 27.4k GitHub stars, and Kilo publishes 5M+ Kilo Coders and more than 10 trillion tokens processed every month. Trusted by developers at Meta, Amazon, Airbnb, PayPal, Square, and Red Hat. The product rebranded from kilocode.ai to kilo.ai in 2026 and won Product Hunt's #1 Open Source Product of the Month. The agent operates across five built-in modes: Architect for system planning, Code for implementation, Debug for diagnosis, Ask for safe codebase exploration, and Orchestrator for multi-step task management with parallel subagent delegation across separate git worktrees. Cloud Agents support headless background execution. A dedicated Security Agent and Code Reviewer extend the platform beyond code generation into security analysis and pull request review. Integration depth spans the full developer workflow: VS Code, JetBrains (IntelliJ, PyCharm, WebStorm), CLI, Cloud Agents, and Slack for team-based task assignment. The platform supports 500+ models via BYOK through OpenRouter, Anthropic, OpenAI, Google Gemini, and any compatible API endpoint with no markup. MCP server integration enables custom tool connections. Gateway and Gastown provide additional infrastructure surfaces. Kilo separates pricing into three independent parts: the platform plan, AI inference, and cloud compute. The platform plan is free and open source forever for individuals under an MIT license. Teams is $15 per user each month for centralized billing, usage analytics, and shared agent management, and Enterprise is custom-priced for SSO, SCIM, audit logs, and SLAs. AI inference runs free through BYOK or local models at no subscription, pay-as-you-go through the Kilo Gateway at exact provider rates with no markup, or on an optional Kilo Pass subscription from $19 per month. Kilo Pass costs the same in either billing cycle and only the credit allowance moves, with an annual commitment earning 50 percent bonus credits against up to 40 percent month to month. A 5 percent processing fee applies to card purchases of credits, including one-off and automatic top-ups and monthly or annual Kilo Pass purchases, and Kilo bills for awake cloud compute time by the second with no rounding or minimum. The fee does not apply to Teams and Enterprise seats, or to payment by invoice, wire, or ACH. Kilo maintains a SOC 2 Type I report through its Trust Center, and on its EU page states that it does not use customer code or prompts to train models or retain them for its own purposes, while noting that the selected provider's data handling policy still applies. Kilo Code is not the right fit for teams that need mature enterprise governance out of the box. GitHub Copilot and Cursor ($16/mo billed annually) provide more polished SSO, audit logging, and RBAC for procurement-heavy enterprise organizations. Tuning Memory Bank, MCP tools, and custom modes has a real learning curve that Cursor or Copilot do not require. Local model performance depends heavily on available hardware, which limits local-first deployments on standard developer machines. Current state Q3 2026: Kilo Code has grown to 27.4k GitHub stars, with Kilo publishing 5M+ Kilo Coders and more than 10 trillion tokens processed every month. The platform expanded from IDE and CLI to include Cloud Agents, Slack integration, Security Agent, Code Reviewer, Gateway, and Gastown. Kilo Mobile for iOS and Android launched in September 2026, an MCP marketplace opened for community-contributed servers, and an EU page added EU-hosted inference routing and provider restriction. The product won Product Hunt's #1 Open Source Product of the Month, and in July 2026 Anaconda acquired Kilo, integrating it as the agentic engineering layer of its AI development platform. Kilo routes work to third-party model providers, some of which may use prompts for training, and ships an organization-level code training opt-out alongside provider filtering by data policy. Fully local model operation is supported for sensitive codebases.

Pros & Limitations

Editorial assessment

Pros

  • ✓Open-source MIT-licensed and model-agnostic with 500+ models: connect any provider through BYOK with no markup, or use Kilo Pass managed inference from $19 per month. 27.4k GitHub stars and 5M+ users validate broad developer adoption.
  • ✓Multi-mode architecture with parallel agents across 6+ surfaces: Architect, Code, Debug, Ask, and Orchestrator modes handle planning and execution as separate concerns with subagent delegation across concurrent git worktrees. Cloud Agents, Slack, and Code Reviewer extend beyond IDE-only workflows.
  • ✓Trusted by developers at Meta, Amazon, Airbnb, PayPal, Square, and Red Hat with $8M seed funding and Product Hunt #1 Open Source Product of the Month award. More than 10 trillion tokens are processed across the platform every month.
  • ✓EU data residency and provider control: the EU page documents EU-hosted inference routing, an approved-provider list, and admin restriction of unsupported routes. Kilo Mobile for iOS and Android extends agent sessions beyond the desktop, and an MCP marketplace collects community-contributed servers.

Limitations

  • –Enterprise governance features (SSO, granular audit logs, RBAC) are less mature than GitHub Copilot or Cursor for procurement-heavy enterprise organizations that require formal security review before deployment.
  • –Setup complexity for advanced features including Memory Bank, custom modes, and MCP tool configuration has a real learning curve compared to Copilot or Cursor which require near-zero configuration for basic agentic coding.
  • –Local model performance depends heavily on available hardware: expect uneven results without sufficient GPU compute for larger open-source LLMs, which limits local-first deployments on standard developer machines.
  • –Code sent through Kilo Gateway can reach model providers that use prompts for training: an organization-level code training opt-out and a provider data-policy filter are available, but the setting that hides prompt-training models is disabled by default.
  • –Review sentiment splits sharply by corpus: its rating on the VS Code Marketplace, by far the largest independent review base, sits well below its G2 and Product Hunt scores, which rest on much smaller samples.

Model architectureModel-agnostic, supports 500+ models including Claude 4.6 Sonnet/Opus, GPT-5, and Gemini 3.1 Pro via OpenRouter or Kilo Gateway
Avg setup timeUnder 5 minutes (install VS Code or JetBrains extension from marketplace, configure BYOK API key or sign up for Kilo Pass, first agent task)
Autonomous ratePermissive by default. Kilo documents that most tools default to allow out of the box, with reading .env files and reaching outside the workspace the notable exceptions that prompt. Orchestrator mode delegates to parallel subagents across concurrent git worktrees with inline diff review, and Cloud Agents run headless in the background. Permissions are configurable per agent to allow, ask, or deny.
