Key differences
Detailed comparison
Privacy & Security: Who sees your data?
OneSchema uses a server-side architecture. When a user uploads a file, it is sent to OneSchema's infrastructure for processing and validation. While they have strong security certifications (SOC 2, HIPAA), the architecture fundamentally requires trusting a third party with your raw data during the import process.
Ivandt processes data primarily on the client-side using Web Workers. Parsing, validation, and transformation happen locally in the user's browser. Your data does not need to be sent to Ivandt's servers to be cleaned. This architectural difference makes Ivandt simpler to approve for security-conscious industries like healthcare (HIPAA), finance, and government.
If your compliance team struggles with sending customer data to third-party processors, Ivandt’s client-side model removes that friction entirely.
Pricing & Accessibility
OneSchema is positioned as a premium enterprise solution. They typically require annual contracts with minimum commitments that can start in the five-figure range ($20k+). They deliver high-touch service and dedicated support, which justifies the cost for large enterprises but can be a blocker for startups and mid-market SaaS.
Ivandt offers a transparent, self-serve model. Plans start at a flat monthly rate ($399/mo) with unlimited imports. There are no "per-row" fees and no sales calls required to get started. It is designed to be accessible to any developer building a B2B product.
OneSchema is built for enterprise procurement cycles. Ivandt is built for developers who want to swipe a card and ship code.
Integration Experience
OneSchema provides a polished, pre-built modal that you embed via an SDK. It behaves largely like an iframe—you configure it, open it, and wait for the "done" callback. The UI is excellent but rigid; you work within their design constraints.
Ivandt is a native Web Component (<ivt-importer />) that sits directly in your DOM. This allows for deeper integration with your app's styling (CSS variables) and flow. It feels less like a "widget" and more like a native part of your application interface.
OneSchema offers a beautiful "out of the box" UI. Ivandt offers a beautiful "adaptable" UI that blends into your app.
Performance & Speed
OneSchema handles large files well by leveraging server-side processing power. However, users must wait for file uploads to complete before validation begins, which introduces network latency for every interaction.
Ivandt leverages the power of modern browsers. By processing data locally in Web Workers, feedback is instant. Users see validation errors immediately without waiting for a server round-trip. For files up to ~500k rows, the client-side experience is often snappier.
Server-side power (OneSchema) vs Instant client-side feedback (Ivandt). For most common use cases, avoiding the network makes Ivandt feel faster.
