Bonsai

Bonsai (hellobonsai.com) is an all-in-one business management platform for service businesses -- freelancers, agencies, and firms -- consolidating client management (CRM, pipeline, proposals, contracts, forms, client portal), project management (tasks, Gantt, time tracking, timesheets, resource planning), and financial management (invoicing, payments, expenses, bookkeeping, rate cards, budgeting and profitability) into one system. Used by 500,000+ small businesses globally. Bonsai exposes its programmatic surface through an official hosted MCP (Model Context Protocol) server at mcp.hellobonsai.com so AI clients (Claude, ChatGPT, Gemini, Cursor, Codex) can act on tasks, projects, deals, contacts, time entries and invoices; a public REST API is documented as forthcoming. Backed by Matrix Partners.

Bonsai is profiled on the APIs.io network. Tagged areas include Company, B2B, Business Management, Freelancing, and Agencies.

Bonsai’s developer surface includes authentication, documentation, pricing, signup flow, engineering blog, support, and 12 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/bonsai: open an issue to ask a question, or submit a pull request to add artifacts.
