Cubent
Agentic AI coding assistant for VS Code that runs on your own API keys for $5/mo.
At $5/mo plus your own API spend, Cubent gets you real agentic behaviour in VS Code for less than most rivals charge for the subscription alone. It moves fast on models — Claude 4.5 landed on 2025-10-08. The catch is structural: Byok assumes you already hold API keys and accept variable spend, so it rewards developers who are fine managing that.

Skip Cubent if you need SSO, shared team workspaces, or a single predictable bill today — Team is still marked Coming Soon and Byok leaves your API usage on a separate, variable bill.
BYOK means you pay your model provider separately from the $5/mo subscription, so your real monthly cost depends on how heavily Agent Mode runs.
Cubent's only purchasable tier is $5/mo on your own API keys, which sits well below Cursor's or GitHub Copilot's seat pricing but excludes model spend. Budget for the subscription plus your provider bill. For a solo developer already holding keys, total outlay is often below a single paid Cursor seat; for a team of five wanting shared config and SSO, there is nothing to buy at any price until Pro and Team ship.
In short

Best for Solo developers and indie founders who want agentic coding in VS Code for $5/mo, Engineers who route tasks across multiple frontier models via their own API keys, Developers working in JavaScript, Python, or Rust who need project-wide context.

What is Cubent?
Cubent — Agentic AI coding assistant for VS Code that runs on your own API keys for $5/mo. Best for Solo developers and indie founders who want agentic coding in VS Code for $5/mo, Engineers who route tasks across multiple frontier models via their own API keys, Developers working in JavaScript, Python, or Rust who need project-wide context. Plans from $5/mo.
Cubent puts an agentic AI coding assistant inside VS Code with a twist: you connect your own API keys from OpenAI, Anthropic, Google, Cohere, Mistral, or OpenRouter, and Cubent supplies the agent loop on top. That arrangement keeps the subscription at $5/month and puts model choice in your hands. The current model roster covers GPT-5, GPT-5 mini and nano, Claude Opus 4.1, and Claude 4.5, which went live on Cubent on 2025-10-08. Pick the cheap model for boilerplate and the strong one for a messy refactor without leaving the editor. Day to day it works across three surfaces. Autocomplete drafts your next block while you accept, tweak, or skip. Agent Mode chains multi-step work through tool calls, from writing tests to refactoring to opening pull requests. Chat Mode handles conversational debugging. Terminal integration runs commands, reads the output, and reacts when something fails, and custom modes let you shape a narrow assistant, such as the security auditor one user built to flag vulnerabilities they'd missed. It reaches past code too. Live browser preview launches from chat, browser automation handles UI debugging, and AI screenshot analysis catches visual regressions before they ship. A live context panel tracks files across the project. Cubent states it never trains on your code, with every action traceable and reviewable. Positioning: against Cursor and GitHub Copilot, Cubent trades their larger ecosystem and bundled model cost for model freedom and a low entry price. You pay API usage separately, so the $5 covers the tool, not the tokens. Byok is the only priced tier today; Pro and Team are listed as Coming Soon.

Behind the verdict
We'd reach for Cubent when the model menu matters more than the monthly bill being fixed. If you already keep OpenAI or Anthropic keys around, the $5 subscription is close to free next to what the tool does — agent mode that plans multi-step work, runs your terminal commands, and reacts when a build breaks. The BYOK model is the whole point and also the main caveat. You get to route a boilerplate task to GPT-5 nano and a gnarly refactor to Claude 4.5 on the same afternoon. What you don't get is predictability: token costs land on your provider account, not Cubent's, so a heavy agent session can cost more than the subscription many times over. If you want one invoice you can forecast, Cursor or GitHub Copilot bundle the model cost — you just accept their model menu. In practice the surface area is broader than a simple autocomplete tool. Browser preview from chat, screenshot analysis for visual regressions, terminal integration, and custom modes all live in the same extension. The custom-modes feature is the sleeper: one user built a security auditor that caught vulnerabilities they'd missed. If your team has a narrow recurring job, that's worth an afternoon of tuning. Where it bites: Pro and Team are still listed as Coming Soon, so anyone needing SSO, shared workspaces, or compliance certifications should wait or look elsewhere today. The free trial is 7 days with no credit card, which is enough to test your real API spend before committing. There's no browser-based IDE — this is a VS Code extension first. Pick Cubent if you're a solo developer or indie founder who wants agentic coding inside VS Code without a $20+ subscription, and you're comfortable with API keys. Pass if you need one predictable bill, enterprise controls, or a team workspace right now. Compared
Models under the hood
as of 2026-10-24
Limitations
- Cubent is in early access; only the Byok plan is purchasable at $5/month, while Pro and Team are listed as "Coming Soon" with no price, so Cubent Units, SSO, shared workspaces, and compliance features cannot be bought today.
- BYOK requires you to supply and pay for your own provider API keys on top of the subscription, so total cost varies with usage.
- The free trial runs 7 days with no credit card required.

GeneratedReal-world workflow fit
Concrete scenarios for the personas Cubent actually fits — and what changes day-one when you adopt it.
Install the Cubent VS Code extension, paste both keys, and run Agent Mode on a legacy module tasked with writing tests and opening a pull request while Autocomplete drafts the surrounding code.
Outcome: Tests are written and a PR is opened without leaving the editor, with every action traceable, and model spend billed by the provider rather than through Cubent.
Build a custom security-auditor mode, point it at the workspace via the live context panel, and have it flag vulnerabilities across all three languages.
Outcome: The auditor surfaces issues that manual review missed, and because Cubent states it never trains on your code, the audit stays inside your own tooling and key accounts.
Launch live browser preview from chat, let browser automation interact with the page, and feed a screenshot into Cubent's screenshot analysis.
Outcome: The visual regression is identified and explained before a manual QA pass, with the fix drafted in the editor.
Use cases
- Generate whole functions or files from a natural-language description inside VS Code
- Debug and fix memory leaks with step-by-step explanations from Agent Mode
- Automatically write tests for a legacy module and open a pull request
- Create Docker and Kubernetes deployment configurations from project context
- Generate documentation from codebase context to speed up onboarding
- Build a full-stack app with social login, database, and CDN
- Analyze screenshots to catch UI issues missed in manual review
- Automate browser testing and debug UI interactions from chat
Setup time & first value
How long it actually takes to get something useful out of Cubent — broken out by persona, not the marketing-page minute.
Solo developer with existing API keys: install the VS Code extension and paste a key — roughly 10–15 minutes to first AI completion. Engineers wiring multiple providers: budget 20–30 minutes, since each of OpenAI, Anthropic, Google, Cohere, Mistral, and OpenRouter is connected separately. Teams: no ETA, because shared workspace and SSO provisioning live on the Team tier, which is Coming Soon.
Switching to or from Cubent
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From GitHub Copilot: install the Cubent extension, connect your own provider keys, and rebuild any custom prompt habits as Cubent custom modes.
- →From Cursor: recreate your editor-level workflow inside VS Code with Cubent, since Cubent runs as a VS Code extension rather than its own IDE.
- →From raw provider chat windows: paste your API keys into Cubent once and move prompt-and-paste coding into Agent Mode with project-wide context.
- ↗To GitHub Copilot: disconnect your API keys and accept Copilot's bundled model set in exchange for one flat seat bill.
- ↗To Cursor: move to a dedicated AI editor if you want editor and model bundled rather than managing your own keys.
- ↗To a browser-based IDE: leave VS Code entirely if you need to code from a machine that cannot run the desktop editor.
