Finance and accounting
Bolsai alternatives
1 open-source project that already does this job. Free to use - not free to run, which is what the numbers on the right are for.
The projects
What you give up either way
- 40+ years of fully adjusted price history and long-running data quality work
- Precomputed TTM fundamentals across many tickers and reconciled accounting choices
- Coverage breadth (350+ equities, 400+ FIIs) and FIIs-specific fields (NAV, vacancy, tenants)
- Enterprise features: SLA, dedicated onboarding, bulk exports and contract-based guarantees
- Polish: consistent field names, CSV export options, and integrations with Claude/ChatGPT via documented patterns
An open-source project doing the core job proves a replacement is possible. It does not prove it matches Bolsai, and it does not prove anyone has run it for a month. How we decide.
