Carpathian builds your software and runs the infrastructure under it.

We run cloud VPS on our own US-based infrastructure and build the software that runs on it. Flat monthly pricing, AI model hosting when you need it, and one team accountable for all of it.

Ship the software you need in months, not years

We are a lean software team that builds custom web and mobile applications and gets them live fast. Fewer people, less process, more shipped. You work directly with the engineers doing the work, from the first call to production.

  • You work with the people building your software, not a project manager relaying messages to a team you never meet
  • We scope hard and build in short cycles, so the budget goes into shipped features instead of coordination
  • The code, the IP, and the accounts are yours, spelled out in our Services Agreement

What we build
  • Custom Applications
    Web and mobile applications shaped around the way your business runs, not forced into a template. Customer portals, booking systems, dashboards, whatever the work needs
  • Internal Tools and Portals
    Admin panels, client portals, and internal systems your team lives in every day. Built to fit your process and fast enough to keep up with it
And the work around it
  • Integrations and Automation
    We connect the tools you already run and automate the manual work between them, so data stops living in spreadsheets and inboxes
  • AI Features
    Search, assistants, and automation powered by AI, built into your product where they earn their place

June was a product launch. Traffic went up roughly fifteen times over March. The amount billed did not move, because compute and transfer are included in the plan rate rather than metered on top of it.

Cloud VPS Hosting Without the Surprise Bill

Simple, flat monthly plans. Build the exact spec you need.

Carpathian Cloud is a managed VPS platform with flat monthly pricing, full root access, and US-based infrastructure. The invoice is the same every month whatever your traffic does, so hosting behaves like a utility rather than a number you have to forecast.

  • Flat monthly cloud pricing with no hourly billing or compute overages
  • US-based VPS infrastructure with active monitoring and uptime SLA
  • Full root access, standard disk images, and no vendor lock-in

What You Get with Carpathian Cloud

A cloud management dashboard, fast VPS provisioning, and platform monitoring in one console. The same infrastructure hosts your cloud servers and your AI models.

Integrated AI for Your Applications

Free to start, then pay for what you use.

Build AI into the applications you ship. Use our hosted open source models through one API, or integrate the providers you already work with like OpenAI and Anthropic, whichever fits your workload. Both run on US-based infrastructure, so your data is processed in the US no matter which path you choose, with the operational simplicity of a managed cloud host.

Access and Integration
  • Open Source Models
    A catalog of open-weight models hosted and ready to call, with nothing to provision or maintain. They run on our own compute in the United States, the same infrastructure behind our managed model hosting, so your prompts are never shipped off to a third-party API
  • Inference API
    The standard /v1/chat/completions interface for chat, embeddings, and completions. Swap your SDK base URL, drop in your API key, and the OpenAI SDKs and client libraries you already use keep working without code changes
  • Usage Analytics and Budget Controls
    Every API key carries its own rate limits, budgets, and geo-aware firewall, with IP allowlisting and automatic lockdown after repeated unauthorized access attempts, so you stay in control of usage and spend
  • Chatbot Interface
    A bundled chat UI for testing models before you integrate them, with no message quotas, no token metering, and no credit card. Open it and start talking
  • Pay for What You Use
    Monthly subscriptions with included tokens, plus on-demand token packs and per-model cost multipliers so you pay in proportion to what you run. Start on the free public chat and scale into the API
Why Build on Carpathian
  • US-Based, Either Way
    Our hosted models and the provider integrations we build both run on US-based infrastructure, so you always know where your data is processed rather than guessing at a region behind someone else’s API
  • Built for Regulated Industries
    US-based infrastructure with backups included, for teams with strict data requirements. Every instance is isolated to your organization, with rate limiting and IP allowlisting available per key
  • One Vendor, One Bill
    The same team running your cloud VPS runs the AI platform. One portal, one invoice, one point of contact

Try the Models Before You Build

Before you wire a model into your application, talk to it. Our public chat lets you test the same models we host, free and running on our US-based infrastructure. When you are ready to build, the same models are available through an OpenAI-compatible API.

carpathian.ai / chat
Which model should I use to summarize support tickets?
For tickets under a few thousand words, Wren is the fastest option and costs the least per token. If the tickets include long email threads, step up to Osprey for better summaries of multi-party context.
Can I call it with the OpenAI SDK?
Yes. Point base_url at api.carpathian.ai/v1 and keep the rest of your code.

The public chat runs the same models the API serves.

Security Built Into Your Cloud and AI Infrastructure

A dedicated security team reviews every host we operate, from cloud VPS nodes to AI inference servers. Security controls are part of the platform, not a separate product you bolt on after an incident.

How We Secure Your Cloud and AI Stack

Every VPS and inference server is hardened at provisioning and watched for anomalous behavior while it runs. When something looks wrong, the response comes from the same engineers you already deal with.

EdgeDDoS mitigation and rate limits before traffic reaches a VPS
AccessRole-based permissions, mandatory MFA, auditable sessions
VPSHardened at provisioning, patched on a tested schedule
CoreIsolated compute per organization, no cross-customer access
Platform Hardening
  • Host Hardening
    Every VPS provisioned with secure defaults. No default credentials, no exposed management ports, no unpatched base images
  • Access Control
    Role-based access across the cloud console and AI hosting dashboard. Mandatory MFA and auditable session logs on every account
  • AI Inference Isolation
    Inference runs inside isolated compute boundaries with per-key access controls. No cross-customer access, no prompt leakage between accounts
Ongoing Protection
  • Continuous Monitoring
    Platform-wide monitoring for intrusion attempts, DDoS traffic, and unusual inference API patterns. Alerts go to a human, not a queue
  • Patching and Updates
    Host OS, hypervisor, and AI runtime updates managed by us on a tested schedule. No surprise maintenance windows during business hours
  • Incident Response
    If something goes wrong, the engineers who run the platform are the ones who respond. No tier-one queue, no handoff

Built for Enterprise

Carpathian is a software architecture and cloud hosting company. We build fast web and mobile applications, host them on our own cloud infrastructure, and add AI where it genuinely helps. Business software has spent decades getting more bloated and harder to use. We build tools that are fast, simple, and worth using, because technology should make work lighter and life better, not add friction to both.

Direct Engineer Access

Senior cloud and AI engineers from day one. The person who provisioned your VPS is the one you talk to when something changes.

One Platform, One Bill

Cloud VPS hosting and AI model hosting in the same console, from the same vendor. No stitching together three providers to ship one product.

Security Background

Our team has experience in government defense and financial systems. That discipline is baked into how we run the platform.

Long-Term Support

We run infrastructure for customers for years, not sprints. The same team is here next quarter, next year, and the one after that.

How We Size Your Stack

Your workload is the spec. We size the cloud plan and pick the AI model deployment that fits how your team runs, not a canned tier designed to force an upgrade six months in.

What Our Clients Say
