Modurian is a hosted multi-agent workspace that turns a prompt into a web project, with an in-browser IDE, live preview and one-click deploy to a public Spaces URL. Models and routing are included, so no API keys are configured.

| Price | from $40/month |
| Free tier | Partly |

One-time grant of 50 credits on Google sign-in, no card required, estimated by the vendor at about 4-6 full builds; credits do not replenish on Free, and agent runs pause once they are spent. Free is limited to Auto routing at low reasoning depth, 4 starter skills (max 3 active), and excludes checkpoints, plugins, the prompt optimizer and Snap-to-Build.

## What it does

**Writes code** · Yes — Build mode authors project files from a chat description, running sandbox commands and iterating until the preview renders as intended.

> Agents write files, run terminal commands, fix errors, and iterate until the preview looks right.
> — https://modurian.com · Workflow section, 'Build — Ship working code' card

**Debugs and fixes** · Yes — The vendor states agents fix errors themselves during a build loop, and Build mode patches existing files with project context.

> Agents write files, run terminal commands, fix errors, and iterate until the preview looks right.
> — https://modurian.com · Workflow section, 'Build — Ship working code' card

**Whole-codebase work** · No — The vendor's own comparison guide sends buyers with a large existing repository to an IDE agent instead, positioning Modurian for new browser-hosted projects.

> Need to extend a large existing monorepo? Use an IDE agent.
> — https://modurian.com/guides/ai-app-builder-comparison · 'A simple decision rule' paragraph

**Ships it** · Yes — Deployment is part of the product: one click publishes the project to a persistent public URL under /spaces, with ZIP export or GitHub push as alternatives.

> One click deploys your project to a public URL. Files persist under `/spaces/{id}` and survive server restarts
> — https://modurian.com/product · 'Deploy with Spaces' section, opening paragraph

**Done-for-you service** · No — Modurian is self-serve software a buyer signs into and operates; nothing on the site offers people who build or run projects on your behalf.

> AI models are pre-configured in the platform. Sign in with Google and start building — we handle the infrastructure.
> — https://modurian.com/product · Capabilities grid, 'Ready on sign-in' card

## How much it does unattended

**Runs autonomously** · Partly — Build mode runs a multi-step loop unattended, but Plan mode explicitly withholds any file write until the human approves and switches modes.

> Read-only planning — architecture, file structure, and steps. No files are written until you switch to Build.
> — https://modurian.com/product · 'Agent modes' section, Plan card

**Multi-agent** · Partly — The vendor names planner and builder agents and markets multi-agent modes, but the modes are user-selected behaviours rather than documented concurrent coordination.

> Planner and builder agents write code, run commands, and show a live preview you can inspect in real time.
> — https://modurian.com · 'From prompt to production' section, step 02

**Agent permissions** · Partly — Permission is controlled only by the mode the user picks: Ask cannot touch files, Plan is read-only, Build has full write and deploy rights with no finer policy.

> Full power — create and edit files, run npm in the sandbox, deploy to Spaces. Use for real development.
> — https://modurian.com/product · 'Agent modes' section, Build card

## Which models it runs on

**GPT** · Yes — OpenAI is named among the AI model vendors that process prompts for Modurian, though the site never states which specific GPT models the router can select.

> We use service providers including Google (OAuth), Stripe (payments), hosting providers, and AI model vendors (e.g. DeepSeek, MiniMax, OpenAI, Google Gemini as configured).
> — https://modurian.com/privacy · Section 5, 'Processors & sharing'

**Model choice** · Partly — Free accounts are locked to Auto routing; manual model choice and reasoning depth controls arrive only with the paid Pro plan.

> Pick Auto to let the platform route each message, or choose a model manually on Pro.
> — https://modurian.com/resources · 'Included models' section, first paragraph

## Where you use it

**In your editor** · Partly — There is a full IDE-style workspace, but it is Modurian's own in-browser editor; no plugin or extension for VS Code or another editor is offered.

> Chat, file tree, syntax-highlighted code viewer, live preview, and agent status — all in one screen.
> — https://modurian.com/product · Capabilities grid, 'Full IDE workspace' card

**On the command line** · Partly — Shell commands run in the hosted sandbox and stream to a build log, but that is the agent's surface; no installable terminal client for the user is documented.

> npm install, build, test — output streams to the build log with color-coded stderr.
> — https://modurian.com/product · Capabilities grid, 'Sandbox commands' card

**In your pipeline** · No — The only git touchpoint is a one-way push to a new GitHub repository from the workspace header; nothing acts on a pull request or runs in CI.

> Export as ZIP or push your project to a new GitHub repo from the workspace header.
> — https://modurian.com/product · Capabilities grid, 'GitHub push' card

**In a browser** · Yes — The product is entirely a hosted browser workspace, combining chat, editor, preview and deployment with nothing installed locally.

> Modurian combines multi-agent AI, an in-browser IDE, live preview, and deployment — with models and routing built in.
> — https://modurian.com/product · Page intro paragraph under 'One workspace. Full stack.'

## Whose machine it runs on

**Self-hosted** · No — Model access, the sandbox and deployed Spaces all run on Modurian's infrastructure; no bring-your-own-infrastructure option appears anywhere on the site.

> Modurian hosts and configures all models — you never paste API keys or manage provider dashboards.
> — https://modurian.com/resources · 'Included models' section, bolded lead sentence

**Open source** · No — The terms reserve ownership of the platform software to the vendor, and no repository or licence is published on the site.

> We own the Service, branding, and platform software.
> — https://modurian.com/terms · Section 7, 'Intellectual property'

## What it costs to run

**How it meters** · Yes — Billing is per credit, deducted from weighted token usage with per-mode minimums, so Build turns cost more than Ask turns.

> Credits are deducted after each agent run from weighted token usage (input + 2× output), with minimums per mode (Build costs more than Ask).
> — https://modurian.com/resources · 'Credits & plans' section, paragraph under the plan cards

**Free tier** · Yes — A Google sign-in grants 50 credits with no card, which the vendor estimates at four to six full builds before a buyer must upgrade.

> Try Modurian with 50 credits — enough for about 4–6 full builds.
> — https://modurian.com/pricing · Free plan card, description line under the $0 price

**Bring your own key** · No — Inference is bundled and keyless by design: the vendor states users never supply provider keys or manage provider dashboards, so own-key or own-cloud inference is not possible.

> you never paste API keys or manage provider dashboards
> — https://modurian.com/resources · 'Included models' section, lead sentence

## Buying it for a team

**A company can buy it** · No — Only individual accounts can be bought today; the vendor places team and organisation billing on its roadmap rather than on sale.

> Team / organization billing is on the roadmap. Today each builder has an individual Free or Pro account.
> — https://modurian.com/pricing · FAQ, 'Is there a team plan?' answer

**Seat model** · No — Pro is a flat individual subscription at one price with no seat count, no minimum and no multi-seat purchase path at all.

> Today each builder has an individual Free or Pro account.
> — https://modurian.com/pricing · FAQ, 'Is there a team plan?' answer

**Pooled budget** · No — Credits belong to the single Google account that signed in, and with no organisation billing there is no shared balance to pool across people.

> Your workspace and credits are tied to that account.
> — https://modurian.com/resources · 'Getting started' section, Step 1 'Sign in with Google'

**Admin controls** · No — With individual accounts only, there is no administrator role; what the agent may do is chosen by the user's own mode selection, not by policy.

> Today each builder has an individual Free or Pro account.
> — https://modurian.com/pricing · FAQ, 'Is there a team plan?' answer

**Single sign-on** · Partly — Google OAuth is the only way in, which covers consumer Google identity but gives no SAML or custom OIDC connection to a corporate directory.

> You sign in with Google OAuth.
> — https://modurian.com/terms · Section 4, 'Accounts'

## What happens to your code

**Data residency** · Partly — The operator is Norwegian and data stays within a named set of regions, but processing may occur in the US or elsewhere and the buyer cannot pin a jurisdiction.

> Data may be processed in Norway, the EU, the US, or other countries where our providers operate.
> — https://modurian.com/privacy · Section 8, 'International transfers'

**Getting out** · Partly — Project export is unrestricted via ZIP or GitHub push and survives cancellation, but credits expire with the billing period and have no cash value.

> Projects and Spaces remain. You lose Pro-only models and features and fall back to Free credit rules. Export anytime.
> — https://modurian.com/pricing · FAQ, 'What happens to my projects if I cancel Pro?' answer

**Certifications** · Partly — GDPR is addressed with legal bases, data-subject rights and transfer safeguards, but no SOC 2 or ISO 27001 certification is claimed anywhere on the site.

> Where GDPR applies: contract performance (providing the Service), legitimate interests (security, improvement, fraud prevention), consent where required
> — https://modurian.com/privacy · Section 4, 'Legal bases (EEA/UK)'
