Frequently asked questions
Balsamiq scores C on the API Report Card. No public REST API for Balsamiq Cloud. The programmatic surface is a read-only MCP server, self-serve via OAuth 2.1 and aimed at AI clients, plus the openly documented BMPR SQLite file format. There are no webhooks, SDKs, or developer portal; write access has no API path.
Balsamiq has an official API, but teams routinely hit its limits: gated access, partial coverage, or paid tiers. Most end up supplementing it with exports or an unofficial API layer like Supergood. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
Balsamiq (Balsamiq Studios, LLC; founded 2008 by Giacomo 'Peldi' Guilizzoni in Sausalito, CA; today a fully-remote ~30-person bootstrapped lifestyle business) builds Balsamiq Wireframes, the canonical low-fidelity wireframing tool.
Vertical: misc, horizontal low-fidelity wireframing / rapid prototyping tool. Not a vertical SaaS in any Supergood-named vertical. Low-fidelity wireframes of mobile and web app screens, intentionally rough so reviewers comment on structure rather than colors/fonts.
Medium-to-low and slowly declining as a standalone, but iconic and entrenched in the PM/founder/consulting niche.
Data that flows through / lives inside Balsamiq Cloud (and .bmpr files for desktop users) on behalf of customer organizations: Wireframes and mockups: BMML XML descriptions of pages, UI controls, positions, sizes, nesting, sticky notes, arrows, and connection lines for mobile and web app concepts.
Founded 2008; Balsamiq Wireframes 1.0 released April 2008. Originally an Adobe Flex / Adobe AIR desktop application, which gave Balsamiq its cross-platform reach in the pre-Electron era.
No public REST API for Balsamiq Cloud, cannot programmatically list projects, create boards, fetch comments, or manage seats outside the MCP read-only surface. No webhooks, third-party systems must poll or rely on first-party Slack / Jira / Confluence notifications. Full sourced list under Sources below.
Common alternatives include Figma + FigJam, Miro, Whimsical, Sketch, Adobe XD (maintenance mode), Axure RP. Graded alternatives appear under "More from the report card" below.
Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
