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.
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.
