Synthetic data is no longer a peripheral experiment. It has become embedded in how modern teams develop, test, and train systems. At its simplest, synthetic data generation (SDG) creates artificial datasets that behave like real data, without the burden of privacy risks or regulatory exposure.

This space is growing rapidly in 2026. The following are five cloud-first platforms shaping how organizations approach synthetic data generation today.

1. K2view

K2view does not position synthetic data as a standalone capability. It treats it as part of a broader data lifecycle – and that philosophy is reflected in the platform’s architecture.

Rather than focusing only on generation, K2view manages the full pipeline: extracting data from multiple systems, subsetting, transforming, and then generating synthetic data that maintains the behavior of the original. A key differentiator is its ability to preserve referential integrity across complex, multi-source environments – an area where many SDG tools struggle in real-world implementations.

The platform combines GenAI-driven and rules-based generation methods, giving teams flexibility depending on whether they prioritize control, accuracy, or speed. It also integrates with CI/CD pipelines, enabling synthetic data to be delivered as part of automated workflows.

The trade-off is complexity. It is not a plug-and-play solution and requires planning, particularly in large enterprise environments. However, for organizations with legacy systems, multiple data sources, and strict governance requirements, that depth becomes a strength rather than a limitation.

Where it fits best: Large enterprises that require scalable, compliant, and self-service synthetic data across complex, heterogeneous environments.

2. MOSTLY AI

MOSTLY AI has built its reputation on accessibility – making synthetic data usable not just for engineers, but for a broader audience.

It offers a clean interface and intuitive workflows, enabling teams to generate high-fidelity datasets that closely resemble real data. One notable capability is its use of fidelity metrics, allowing users to measure how closely synthetic data aligns with original datasets – a feature often overlooked in simpler tools.

The platform supports multi-relational datasets and integrates via APIs, making it suitable for analytics and model training pipelines. However, flexibility can decrease when dealing with highly complex or deeply hierarchical data relationships.

Overall, MOSTLY AI is well suited for teams that prioritize ease of use and speed over deep customization.

Where it fits best: Mid-sized to large organizations needing fast, privacy-safe synthetic data generation with minimal complexity.

3. YData Fabric

YData Fabric operates at the intersection of data preparation and synthetic data generation. It not only generates synthetic data, but also helps teams understand and improve data quality before using it in machine learning workflows.

The platform supports multiple data types – including tabular, relational, and time-series – and combines data profiling with generation. This integrated approach can significantly improve dataset readiness for AI models.

However, the platform assumes a certain level of data science expertise. It is less accessible to non-technical users and may not meet the full range of enterprise compliance requirements found in more governance-focused solutions.

Where it fits best: Teams building ML models that require both data preparation and synthetic data generation in a unified environment.

4. Gretel workflows

Gretel approaches synthetic data from a developer-centric perspective. Rather than focusing on user interfaces, it emphasizes embedding synthetic data generation directly into engineering workflows.

The platform supports structured and unstructured data, and enables automation through pipeline scheduling, APIs, and CI/CD integration. This makes it particularly effective in environments where data must move quickly between development, testing, and production stages.

While it offers no-code and low-code options, its primary strength lies in API-driven workflows. Its cloud-first architecture and developer orientation may limit accessibility for non-technical users.

Where it fits best: Engineering teams embedding synthetic data into DevOps, testing, and machine learning pipelines.

5. Hazy (now part of SAS data maker)

Hazy takes a compliance-first approach to synthetic data generation. Rather than treating privacy as an afterthought, it builds on techniques such as differential privacy and advanced anonymization to enable safe data sharing.

This makes it particularly relevant for regulated industries such as financial services, healthcare, and insurance. The platform supports both cloud and on-prem deployment and integrates with enterprise systems.

That said, this level of compliance introduces complexity. Implementation can be time-consuming and may require specialized expertise.

Where it fits best: Highly regulated organizations that require secure, compliant synthetic data for data sharing and analytics.

The bigger shift

In 2026, the conversation is no longer about how many synthetic data tools exist, but about how effectively they are integrated into development workflows.

Synthetic data is no longer just a workaround – it is becoming a foundational layer in modern data architectures, particularly where AI, privacy, and speed intersect.

The direction is clear. As AI models become more data-intensive and privacy regulations tighten, synthetic data is evolving into a core capability. The platforms that will stand out are those that balance realism, control, compliance, and seamless integration – without slowing down delivery.
