Misata vs Syntho
Syntho is a funded enterprise platform built around privacy-preserving synthesis from real data. You connect it to your existing databases, it learns statistical patterns, and it produces synthetic copies that preserve those patterns. It is a serious product aimed at banks, insurers, and large healthcare systems that need a vendor relationship, compliance artifacts, and a support contract. Misata solves a different problem: you describe the dataset you want and a deterministic math engine builds it from scratch, with no real data involved at any point, exact declared outcomes, and an integrity proof attached. If you have production data and need a managed enterprise platform to generate privacy-safe copies of it, Syntho is worth evaluating. If you need relational data from a specification, self-serve in seconds, free, and running entirely on your machine, Misata is the tool.
| Capability | Misata | Syntho |
|---|---|---|
| Requires real data to start | No. Generates from a specification. | Yes. Connects to your existing databases. |
| Self-serve, no sales call | Yes. Try it in 30 seconds. | No. 'Book a Demo' gate for access. |
| Runs locally, data never leaves your machine | Yes. Fully offline capable. | No. Cloud platform. |
| Open source | Yes. MIT licensed. | No. Proprietary. |
| Exact declared aggregates | Yes. Closed-form math, to the cent. | Approximate. Learned from training data. |
| MCP server for AI agents | Yes. Built in. | No. |
| Free to use | Yes. No limits, no account required. | No. Enterprise subscription. |
| Privacy-safe copy of existing data | Use Misata mimic mode for single-table. For full production replication, SDV goes further. | Yes, its core strength. |
| Enterprise compliance (SSO, RBAC, audit trails) | No. It is a library, not a platform. | Yes. |
| Vendor support contract | No. Direct access to the developer. | Yes. |
Why these tools target different situations
Syntho's product requires connecting to a production database and using it as training data. The platform learns the statistical relationships in your real data and produces synthetic rows that resemble them. This is the right approach for a regulated enterprise with production systems, a compliance team that needs a vendor on record, and a requirement for privacy-safe copies of data that already exists. Misata starts with a blank slate. You tell it what the dataset should look like. The engine builds it from that specification, not from any real records. Foreign keys resolve because the engine wires them in the correct order, not because it learned them from production. Aggregates hit declared targets because the math enforces them, not because a trained model approximated them. The two tools serve different moments in a company's lifecycle and different kinds of problems.
The self-serve gap
Syntho's website does not have a free trial or a self-serve path. Every entry point is a demo request form. That is appropriate for enterprise buyers who expect a sales process and a pilot. It is a dead end for a solo developer, a startup engineer, or anyone who wants to see the data output before committing anything. Misata has no sales process. Visit misata.studio, describe what you need, and get data in under a minute. The Python library is pip install away. The MCP server works in Claude, Cursor, and Windsurf without an account. That difference in friction is the first reason developers reach for Misata.
The exact outcomes problem
When you tell a trained model that monthly revenue should grow from $80k to $200k, it does not understand that as a constraint. It generates data that looks like whatever it learned from the training distribution. If your training data had flat revenue, the synthetic output will have approximately flat revenue. Misata treats your declaration as a hard constraint and solves it in closed form, which is the approach we published in a research paper because it is formally different from approximation. If you need to build a pipeline test where you know the exact answer in advance, or a demo where the chart hits a specific number you promised a client, a trained model cannot give you that guarantee. Misata can.
Where Syntho is the better choice
If your team sits inside a regulated enterprise that requires ISO 27001 evidence, GDPR data processing agreements, a named vendor, and quantifiable re-identification risk scores on synthetic output, Syntho provides all of that. Misata does not. It is a library and a studio, not a compliance product. For teams that need a privacy-safe statistical copy of an existing production dataset, and have the data residency clearance to move that data through a cloud platform, Syntho is a serious option. We are honest about this because credibility is more useful than persuasion.
Frequently asked
Is Misata a Syntho alternative?
For the specification use case, yes. If you need to generate relational data from scratch with exact declared outcomes, no real data needed, and no vendor relationship required, Misata covers that entirely. For privacy-safe synthesis from existing production data at enterprise scale with compliance artifacts, Syntho is built for that specifically.
Can I use Misata without signing up or talking to sales?
Yes. Visit misata.studio and start generating in under a minute. No sign-up required for the basic studio. The Python library is pip install misata. The MCP server is pip install misata[mcp]. No account, no demo request, no sales process.
Does Misata work for regulated industries like banking and healthcare?
Yes. Because Misata generates from a specification rather than from real data, there is nothing to leak, no membership inference risk, and no PII that needs to be scrubbed. Healthcare teams use Misata to generate HIPAA-shape datasets for pipeline testing and demo environments. Fintech teams use it for datasets with declared fraud rates and transaction volumes. Neither group needs to upload production data to get there.
How does Misata's pricing compare to Syntho's?
Misata is free. The engine is MIT licensed, the studio is free to use, and there are no usage limits or paid tiers on core generation. Syntho uses enterprise subscription pricing that requires a sales conversation to establish.
Does Misata run locally or in the cloud?
Misata runs locally by default. The Python library runs entirely offline. The studio processes generation on your machine. Nothing about your schema or generated data is sent to any server unless you explicitly export it. For teams in air-gapped environments or with strict data residency requirements, local execution is the feature, not a limitation.
