Simudyne Pulse vs Synth Studio

Simudyne Pulse generates synthetic financial-market data through APIs and a Python SDK for research, model training, algorithm development, and backtesting. Its PulseABM simulator produces data at millisecond resolution, including synthetic order books, L1/L2/L3 data, individual order events, and executed trades for HKEX and LSE. Listed uses include backtesting algorithms, measuring market impact, pre-trade transaction-cost analysis, stress scenarios, and model training. The simulated exchange is available over FIX 4.4 and can run at up to 20× speed. A Pulse MCP server exposes market-data and backtesting tools to compatible assistants such as Cursor, Windsurf, VS Code with GitHub Copilot, Cline, and Zed. The Python SDK returns data as Polars DataFrames, with Parquet and ZIP output formats. Pulse is cloud deployed and available through web and API platforms. Its free plan offers pre-run cached simulations, up to 10 Monte Carlo runs per group, and a selection of HKEX and LSE symbols, dates, and scenarios. Free-tier downloads are capped at 3 new simulation groups per rolling 24-hour period; previously downloaded groups can be fetched again for free.

Synth Studio generates synthetic tabular datasets with mathematical privacy guarantees. It accepts CSV and JSON files and detects their schemas automatically. Generation options include CTGAN, TVAE, GaussianCopula and schema-based methods. Differential privacy settings can be configured with epsilon and delta, using RDP accounting. Quality tools assess statistical similarity, machine-learning utility and privacy leakage, while automatic PII detection identifies fields such as names, emails and SSNs before generation. The product provides compliance reporting for HIPAA, GDPR, CCPA and SOC-2, alongside audit logs and model cards. Synth Studio is open source and can be self-hosted or used through its cloud offering. Local installation documentation lists Windows 10+, macOS 10.15+ and Linux. The free plan is free for up to 1 million rows per generation under an MIT License. REST API integration is available, but direct API access currently requires a session cookie or trusted proxy headers; API keys are upcoming. Documented API limits include 1,000 authenticated requests per minute and five concurrent generation jobs.
