Kilo Code Review 2026: Free Agent Power, 500+ Models, and What Changed After the Metabase Incident
Kilo Code review 2026: a free, open-source coding agent spanning VS Code, JetBrains, CLI, and the cloud, with 500+ models at zero markup — the July 2026 Anaconda acquisition, the August 2026 Metabase data exposure, documented infinite-loop bugs, and honest pricing math.

Kilo Code review 2026: like its closest open-source rival Cline, Kilo Code's core pitch is that the software costs nothing — free, open-source, MIT-licensed — and you only pay for the AI inference your sessions actually use, at exact provider rates with no markup through Kilo's own gateway. What sets it apart on paper is scale: 500+ models across 60+ providers, four distinct agent modes (Code, Plan, Ask, Debug), codebase-wide semantic indexing, and both local and cloud-based agent execution, with sessions syncing across VS Code, JetBrains, CLI, mobile, and web.
Two developments in 2026 changed what evaluating Kilo Code actually means. On July 15, 2026, data-science platform Anaconda acquired Kilo Code outright, folding it into a broader "trillion-token" AI development strategy — a real signal of backing for a tool that started as an open-source side project. Less than a month later, on August 2-6, 2026, Anaconda disclosed a Metabase-related incident that exposed prompts and user data for a subset of Kilo users, including Slack access tokens for some Slackbot integrations. Both facts matter to this review, and neither cancels the other out.
This review covers the real breadth of what Kilo Code offers, alongside the incident, two listed CVEs, and a documented pattern of runaway sessions — the same category of risk this site flagged in its recent review of Cline, Kilo's nearest open-source competitor, because it's a risk class the entire agentic-coding category shares, not a one-off flaw unique to either tool.
What Kilo Code Actually Does
Four agent modes
Code mode edits files directly, Plan mode proposes architecture before touching anything, Ask mode answers questions without making changes, and Debug mode focuses specifically on troubleshooting failures.
Codebase indexing
Semantic search across the full repository lets the agent find relevant code automatically, rather than relying only on whatever files happen to be open.
500+ models, 60+ providers
Switch models mid-task, use your own API keys, or route through Kilo's gateway at the exact rate the underlying provider charges — Kilo states no markup on gateway pricing.
Cloud Agents & Code Review
Run agents in the cloud rather than locally, and get automated PR reviews with inline feedback — both billed as separate compute usage from model inference.
MCP marketplace
Install agents, skills, MCP servers, and plugins to extend capability — including documentation-lookup tools aimed specifically at reducing hallucinated API usage.
Team & Enterprise governance
Usage analytics, an "AI adoption score," shared BYOK, centralized billing, model/provider restrictions, audit logs, and SSO/OIDC/SCIM for larger organizations.
The Metabase Incident & Documented CVEs
Between August 2 and 6, 2026, Anaconda disclosed that a security incident involving Metabase — a business-intelligence tool Kilo's team used internally — exposed data for a subset of Kilo Code users. Anaconda's own incident writeup specifies that exposed data included user prompts and account information, and, for some users of Kilo's Slackbot integration specifically, Slack access tokens. This is a different category of incident than a prompt-injection exploit: it's a data exposure tied to internal tooling, not an attacker manipulating the AI agent itself.
Separately, two CVEs are publicly listed against Kilo Code in the National Vulnerability Database: CVE-2025-11445, describing a prompt-injection issue, and CVE-2026-8765, describing a path-traversal vulnerability in specific versions. Both are the kind of findings that show up in actively audited open-source security tools — their existence in NVD is itself a sign the project is being scrutinized by outside researchers, which is a healthier sign than no CVEs at all for a tool with this much system access.
None of this is reason to treat Kilo Code as uniquely unsafe among AI coding agents — the Metabase incident involved internal tooling common to many SaaS companies, and CVEs get filed against actively-used software, including Kilo's direct competitors. But Slack token exposure specifically is a real, concrete consequence for any Slackbot-connected user, not an abstract risk, and anyone using that integration should check whether they were notified and rotate credentials if there's any doubt.
Pricing — Free Core, Zero-Markup Gateway
The core VS Code, JetBrains, and CLI extensions are free under MIT, with three ways to pay for inference: bring your own provider key, run a local model via Ollama or LM Studio at zero cost, or route through Kilo's gateway at exact provider rates plus a 5% processing fee on credit purchases. Kilo Pass adds monthly credit subscriptions with bonus credits layered on top — Starter at $19/month nets up to $26.60 in usable credits, Pro at $49/month nets up to $68.60, and Expert at $199/month nets up to $278.60, with annual billing adding a further 50% bonus. Teams runs $15/user/month for shared billing and basic governance; Enterprise is custom, and also listed on AWS Marketplace at $1,800/user/year.
Pros & Cons
Kilo Code vs. Cline vs. Cursor vs. OpenCode
Best for developers wanting maximum model choice (500+) and cloud agent options, now backed by Anaconda's institutional resources.
A leaner, more established open-source core (69.9K GitHub stars vs. Kilo's 27.5K) with its own MCP marketplace and a cleaner security incident history to date.
Cursor for a fully managed, polished IDE experience at a flat $20/month; OpenCode for an even more permissive MIT license with a larger open community — Kilo's CLI is itself built as a fork of OpenCode's server.
Who Should Use It
Ideal user: a developer or team that wants the broadest possible model selection and the option to run agents in the cloud as well as locally, who's comfortable managing spend across both token inference and separate cloud-compute billing, and who values Anaconda's backing as a signal of longer-term support.
Look elsewhere if: you want the cleanest security track record available in this category today (Cline's incident history, while real, is narrower in scope), you're using Slack integrations and want to avoid the specific token-exposure risk the Metabase incident created, or you'd rather not track two separate cost dimensions (inference plus cloud compute).
Expert Editorial Opinion
Kilo Code's core value proposition is genuinely hard to argue with on paper: free software, zero-markup inference pricing, and access to more models than almost any competitor in this category offers. For a developer who wants to try five different models on the same task without committing to one lab's ecosystem, that breadth is a real, practical advantage — not a marketing checkbox.
The Anaconda acquisition is worth taking seriously as a maturity signal rather than dismissing as corporate noise. A well-capitalized data-science company buying an open-source coding agent outright, explicitly to anchor a broader AI development strategy, is a meaningfully different trajectory than a small team maintaining a project on donated time. Whether that translates into faster security response and more consistent long-term support remains to be proven, but it's a reasonable basis for more confidence than the project had a year earlier.
The Metabase incident deserves a direct, un-softened assessment rather than a glossed-over mention. Exposing user prompts and Slack access tokens, even for a subset of users, is a real consequence with a real fix required on the affected users' end — rotating any potentially exposed Slack tokens isn't optional caution, it's the correct response to this specific disclosure. Anaconda's own public writeup is detailed and dated, which is the right way to handle a disclosure like this, and that transparency should factor into the assessment alongside the fact that the incident happened in the first place.
The infinite-loop and settings-persistence bugs documented on GitHub are a smaller concern individually, but they paint a consistent picture worth naming: Kilo Code, like most agentic coding tools racing to ship features in 2026, has rough edges that show up in real usage, not just edge-case lab conditions. An $7.59 token-burn incident is a minor financial loss on its own; it's evidence of a pattern that could cost considerably more under worse conditions, and that's the lens worth applying rather than dismissing it by its dollar amount alone.
Set against Cline specifically — its closest open-source peer — Kilo Code trades a somewhat rockier recent track record for genuinely broader model access and cloud agent capability. Neither tool is simply "better." A developer prioritizing the widest possible model selection and willing to actively manage the risks documented here has real reasons to choose Kilo. A developer who weighs a cleaner incident history more heavily has equally real reasons to lean toward Cline instead. This review's job is to make both of those reasons visible, not to flatten them into a single winner.
Final Verdict
Kilo Code earns real credit for genuinely broad model access, zero-markup gateway pricing, and real institutional backing following Anaconda's acquisition. The score reflects documented risks that keep this from a higher mark: the August 2026 Metabase data exposure incident affecting prompts and Slack tokens for a subset of users, two listed CVEs, and recurring bug reports around infinite loops and settings persistence. For developers who prioritize model breadth and are prepared to actively manage security hygiene — rotating any potentially exposed credentials, staying current on updates — this is a capable, well-resourced tool; it's not yet the cleanest security track record in its category.
