Features and specs

What each product offers, as listed by its team.

https://open-gpt.app/ 5 features
Prolyz 5 features
  • Accessible AI Chat Interface
    Provides a user-friendly web-based interface for interacting with GPT-based AI models without needing to set up API access or coding knowledge.
  • No Installation Required
    Being a web application, it can be used directly from a browser without downloading or installing any software.
  • Potentially Free or Low-Cost Access
    Many GPT wrapper sites like this offer free tiers or lower-cost access compared to official API pricing, making AI chat more accessible to casual users.
  • Quick Setup
    Users can typically start chatting almost immediately after visiting the site, with minimal account creation or configuration steps.
  • Cross-Platform Compatibility
    Since it runs in a browser, it can be accessed from various devices including desktops, tablets, and smartphones without platform-specific versions.

Possible disadvantages

  • Uncertain Reliability
    Third-party GPT wrapper websites often depend on underlying API access that can be unstable, rate-limited, or discontinued without notice, affecting consistent availability.
  • Data Privacy Concerns
    Using an unofficial third-party service to process conversations raises questions about how user data and conversation history are stored, used, or shared.
  • Limited Transparency
    It may be unclear which underlying AI model version is being used, how up-to-date it is, or what modifications have been made to the base model's behavior.
  • Potential Hidden Costs or Ads
    Free-to-use AI wrapper sites often monetize through ads, premium upsells, or data collection, which may not be clearly disclosed to users upfront.
  • Lack of Official Support
    Unlike official AI platforms, unofficial wrapper sites may lack dedicated customer support, regular updates, or accountability if issues arise.
  • Real-time CDC
    Log-based change data capture streams every insert, update and delete the moment it is committed, across 50+ connectors.
  • Built-in OLAP analytics
    ClickHouse engine included: interactive reports and ML forecasting on live data, with no separate warehouse to stand up.
  • Causal AI
    Causal inference (Pearl, DoWhy) explains why a number moved, not just that it did, with the reasoning attached.
  • Privacy-first local AI
    All AI reasoning runs on a local model inside your environment. Neither data nor metadata leaves it. GDPR and KVKK aligned.
  • Governed catalog & lineage
    Every asset cataloged with column-level lineage, quality scoring, quarantine rules and domain ownership.

Questions & Answers

As answered by people managing https://open-gpt.app/ and Prolyz.

What makes your product unique?

Prolyz's answer:

Three things that rarely ship together in one platform:

  • Built-in OLAP. A ClickHouse engine is part of the product, so interactive analysis and ML forecasting run on live data with no separate warehouse to stand up.
  • Causal AI, not correlation. Prolyz Agent uses causal inference (Pearl's framework via DoWhy) to isolate why a number moved, and returns the reasoning with the answer.
  • Privacy-first local AI. All reasoning runs on a model inside your environment. Neither data nor metadata leaves it, which is what makes on-premise and air-gapped deployments possible.

Underneath, four governed layers hand data to each other: Data (catalog, lineage, quality), Sync (real-time CDC and ETL), Report (OLAP analytics) and Agent (decisions).

Why should a person choose your product over its competitors?

Prolyz's answer:

It depends on what you already run, and we try to be honest about that.

  • Against pipeline tools (Fivetran, Airbyte): they move data into a warehouse you still have to buy, model and report on. Prolyz moves it and then governs, analyses and explains it in one platform.
  • Against enterprise suites (Informatica): they are deeper in master data management, but reporting and reasoning live in other vendors' tools. Prolyz ships built-in OLAP and causal AI.
  • Against BI (Power BI, Tableau): a dashboard shows what changed. Prolyz Agent traces why, with causal inference rather than correlation.

And one hard requirement others rarely meet: everything, including the AI, can run on-premise or air-gapped, with no data or metadata leaving your environment.

How would you describe the primary audience of your product?

Prolyz's answer:

Data and analytics teams in mid-market and enterprise organisations that run business-critical systems (SAP, CRM, operational databases) and are expected to answer questions faster than a nightly batch allows.

Typical buyers: heads of data, BI and analytics leads, data engineers and CTOs. The strongest fit is regulated sectors, finance, insurance, healthcare, public sector and manufacturing, where data has to stay on-premise or in-country and every number needs an audit trail.

Common starting point: a team that already has dashboards, but where the question "why did this change?" still takes days.

What's the story behind your product?

Prolyz's answer:

Prolyz was founded in 2026 by two engineers who had spent years building data platforms for enterprises, and kept watching the same thing happen: the pipelines worked, the dashboards were accurate, and nobody could say why a number moved. Answering that took days of exports, meetings and guesswork.

The second pattern was regulatory. In finance, insurance and the public sector, the answer to "can we send this data to a cloud model?" was simply no, which ended most AI projects before they started.

So Prolyz was built around two commitments: reason about causes rather than correlations, and do it entirely inside the customer's environment. The company is registered in London as Prolyz Ltd, with engineering in Istanbul.

Which are the primary technologies used for building your product?

Prolyz's answer:

  • Services: .NET 8 microservices behind a YARP gateway, OAuth 2.0 / OIDC via OpenIddict, RabbitMQ and MassTransit for events.
  • Data path: PostgreSQL for OLTP, log-based CDC into ClickHouse for OLAP, Redis for cache, Qdrant for vector search.
  • AI: Python and FastAPI with DoWhy for causal inference and local LLMs (Ollama) so nothing leaves the customer's environment; MCP servers pull external context.
  • Frontend: React and Next.js.
  • Operations: Docker and Kubernetes with Helm, OpenTelemetry, Prometheus, Grafana, Loki and Tempo.

Deployment: managed SaaS, hybrid, or fully on-premise and air-gapped, from the same codebase.
