What is Bonsai?

Bonsai is assembling a real CRM underneath the freelancer billing tools

Bonsai's recent work is system-of-record plumbing: a Notes section spanning contacts, companies and projects, an activity feed per company, and Gmail/Microsoft sync that files email and calendar events against the right record. Alongside it sit a self-serve API key and an MCP connector. Billing is no longer the centre of gravity.

What is OpenProject?

OpenProject settles into patch work after 17.7 shipped resource management.

17.7.0 was the substantial release — a resource management module with departments and work schedules, pushing OpenProject past task tracking into staffing. The two releases since are patches. 17.7.2 fixes four bugs, among them project-level hourly rates that could not be adjusted and non-working days silently dropped when saved while a reschedule job was running — both in the scheduling and cost areas 17.7 had just expanded.

Bonsai vs OpenProject: editorial side-by-side

B5.0

Bonsai is assembling a real CRM underneath the freelancer billing tools

◆ Current state

Bonsai's recent work is system-of-record plumbing: a Notes section spanning contacts, companies and projects, an activity feed per company, and Gmail/Microsoft sync that files email and calendar events against the right record. Alongside it sit a self-serve API key and an MCP connector. Billing is no longer the centre of gravity.

◆ Where it's heading

The pieces landing are the ones a CRM needs before it can be trusted as the single place client history lives — cross-record linking, per-object permissions, automatic contact capture. The API and MCP connector point the same data outward, reachable from outside the app. Documents was rebuilt on that footing, folding proposals and contracts into one editor.

◆ Prediction

Expect the per-object permissions introduced with Notes to spread to the other record types, and the API surface to widen now that a key can be generated self-serve.

O6.3

OpenProject settles into patch work after 17.7 shipped resource management.

◆ Current state

17.7.0 was the substantial release — a resource management module with departments and work schedules, pushing OpenProject past task tracking into staffing. The two releases since are patches. 17.7.2 fixes four bugs, among them project-level hourly rates that could not be adjusted and non-working days silently dropped when saved while a reschedule job was running — both in the scheduling and cost areas 17.7 had just expanded.

◆ Where it's heading

The release rhythm is a feature minor followed by a short tail of patches repairing the surface it just added, and this tail sits squarely in resource-management territory. Rate and non-working-day bugs are the predictable cost of shipping scheduling and cost tracking together. For self-hosted operators the advice does not change between these releases: take the patch.

◆ Prediction

Expect one or two more 17.7.x patches against the resource management surface before 17.8 opens a new feature line.
