The whole survey study, in one repository.
Write the questionnaire as a Python file, deploy it to a live survey, collect responses, analyze the data, and ship the report — all in one place. With Siamang Cloud, every project lives in its own Git repo where the entire study happens.
Open beta · 30-day Pro trial · no credit card · no signup to demo
A fragmented toolchain no one can reproduce.
The questionnaire is built in one tool, data stored in another, analysis done on someone's laptop, reports somewhere else. Six months later, no one can reconstruct how a number was produced.
One repository, from question to report.
No tool sprawl. Every step below happens in the same project repo — authored, run and versioned together.
A source-available engine. A managed cloud.
The Python engine. Define the questionnaire, validate, simulate, deploy and analyze — the entire pipeline from a single Python script. Version-controllable, testable, reusable.
A cloud Git service where every project lives in its own repository — write the questionnaire, deploy it, analyze responses and build reports, all in one place. Hosting, database, dashboards, teams and automation included.
Every project is a repository. Everything lives there.
Browse the file tree, edit the questionnaire and analysis scripts, and wire the whole study together in siamang.yaml — commit and deploy without ever leaving the browser.
What's inside every project
