Anyone can build version one. Nobody maintains it. That is the gap.

Your business runs on spreadsheets, email chains and SaaS tools that each do 70 percent of the job. You know exactly what you need. There is nobody to build it, and no appetite for a six month project or a freelancer who disappears. Chromoly is for people who need custom software and do not have a development team. A system that exists next week and still works in two years.

How it works

From a sentence to a system you can keep changing. Five steps.

01

Describe

Write what you need in plain language, or plan it with the AI first. No technical wording.

02

Blueprint

Your description becomes a readable blueprint: every entity, workflow and dependency written down. The blueprint is the system, and it is yours.

03

Compile

An engine turns the blueprint into the working system, the same way every time. Review it in your browser, then test the actions before deploying.

04

Change

Ask in chat and the blueprint updates. Every change shows what it touches before it applies - safe or breaking, you know before you say yes.

05

We run it

Hosting, monitoring and patches for the life of your account. Failures show in run history and alert you, and we help fix them.

Permanent architecture

Your system lives in a blueprint, not someone's head.

PLAIN LANGUAGEyou describe it BLUEPRINT V1the spec, versioned RUNNING TOOLcompiled, then run BUSINESS CHANGEa rule moves BLUEPRINT V2blast radius first UPDATED TOOLsafely evolved Every change flows through the blueprint - never ad hoc.

A versioned spec, not tribal knowledge.

In chat-based builders, the only place your app's structure exists is the chat history - and the chat history runs out. Here, every build is defined as a structured blueprint: every entity, field, workflow, integration, and dependency mapped and machine-readable. When people leave, the knowledge stays.

Maintained for the life of your account.

We run your systems on managed infrastructure: monitoring, security patches, model upgrades. When your process changes, you describe the change, every change shows exactly what it affects, marked safe, affected, or breaking, before it applies. Failures are visible: every run is logged, errors show in run history, and you are alerted.

What every system ships with

Built to be trusted.

Data and AI controls

Hosted in the EU.

Your application database is hosted in Supabase, Ireland. Choose Global AI or the Mistral EU route when its regional and privacy requirements are approved. Shared AI requests are audited, and an unavailable EU route never silently switches to Global. Read how processing works.

EU data residency (Ireland)DPA and privacy termsEU AI subject to approvalAI request audit trail

Every app is served on its included address. Connecting your own domain after deployment is built and waiting for release. Read the custom domain guide.

Dependency map

See what a change touches. Before you apply it.

Every saved version carries a map of its own structure: fields, tables, APIs, components, pages, routes, workflows, integrations and roles, with the relationships between them. Select anything to see what depends on it, search it, filter by type or read the relationships as a list. Viewing the map is read-only and uses no AI credits.

Running on our development environment. The map is static analysis, not proof: it tells you what to review, and your own tests still decide whether a change is safe.

Field edits flag the consumers of the whole table, and dynamic table names or custom code can have effects the map cannot see. How change review works →

AI client connections · Global mode

Connect your AI client. You control access.

Use MCP to share selected app records, chart data and saved PDF text with a compatible external AI client. Connect through OAuth sign-in or a scoped token, with permissions you choose in App settings.

Deployed and verified on our development environment; public rollout is pending. Contact us about availability. External clients use their own provider’s data-processing terms. MCP is available only for Global-mode apps.

Actions depend on what your app supports. Every change and workflow-control request requires owner approval. Explore MCP setup and permissions →

FAQ

Common questions.

What can I build with Chromoly?

Build websites, portfolios, internal tools and AI automations: CRMs, dashboards, booking portals, invoicing, onboarding and AI-assisted workflows. Start with one use case, and ask explicitly if you want several combined. AI agents are planned for a future release.

Does the AI build the app?

The selected model plans the build and proposes edits. Chromoly’s compiler assembles the app from the structured blueprint. You review the preview, test its actions and configure external services before deployment.

Which models can I choose?

Global builds default to a frontier OpenAI model, with a Claude model as an alternative you pick before a build. In-app AI in Global mode runs on a faster Claude model. Chromoly integrates directly with OpenAI, Anthropic and Mistral; there is no gateway in between. The current choices appear in the selector, and newer releases are added only after review.

Can I build a booking portal with payments?

Yes. Booking apps can include services, a customer page, availability and a calendar. Configure email or Slack notifications and your own Stripe Payment Links. Automatic payment confirmation requires the booking webhook and signing secret, with matching amounts and test/live mode. Test the complete flow before using live payments.

Will dashboard charts add new months automatically?

Rolling monthly charts advance with the app’s reporting time zone when connected to dated records. You do not prompt in each new month. Reporting apps can include line, bar and pie charts. History must come from real records or snapshots; it is not invented.

Can I choose my colors, logo and theme?

Yes. Request a color or exact hex value in your prompt. App owners can save App default, Light or Dark appearance and add a logo. Supported customer booking pages reuse the branding and can have their own owner-selected theme. Standalone app views can use the logo as a favicon.

Does every app include AI?

No. AI features are included when the workflow needs them. Apps without executable AI do not show in-app AI settings. For apps with AI, shared-gateway requests are audited without storing prompt and response content in the audit trail.

Where is my data processed?

The application database is hosted in Supabase, Ireland. Global AI requests may be processed outside the EU. The Mistral EU route is enabled only after the required regional, privacy and account reviews, and it stops if those requirements are not met. Review our Privacy Policy, DPA and subprocessor list for the applicable scope.

Can I build in Swedish?

Yes. English and Swedish app interfaces are supported. Specify the language, reporting time zone and currency in your prompt.

Can Chromoly handle a larger app?

Larger structured apps use saved generation phases. Complexity, provider limits and validation can still affect completion. Contact us about your expected app size and rollout; we do not promise that every prompt or workload will succeed.

How do plans and early access work?

This site describes the launch build as it runs on our development environment. Nothing here is self-serve yet, and nothing has been used by a paying customer. The offers below describe the planned Free, Builder and Pro plans, plus Managed with custom pricing after a discovery call. Production purchasing depends on billing setup, and checkout confirms your actual terms. For early access or a custom plan, email hello@chromoly.io.

Can I connect an external AI client to my app?

MCP connections run on our development environment for Global-mode apps, and public rollout is pending. Compatible clients can use OAuth or a scoped token to read selected data, request supported app actions and monitor workflows. Owners choose permissions and approve changes and workflow controls in Chromoly. Disconnecting blocks future access; approved workflows need separate cancellation. Contact hello@chromoly.io about availability. Read the MCP guide.

How do I get help?

Email hello@chromoly.io. For a build issue, include the app or build reference, the time and what happened. Do not include passwords, API keys or private customer records.
