Frequently asked questions
Kaltura scores A on the API Report Card. Kaltura's VPaaS REST API at developer.kaltura.com is self-serve and covers media upload, content management, live streaming, analytics, and a separate OTT API. Client libraries are auto-generated for nine languages. Auth is session-based off a partner admin secret rather than OAuth.
Kaltura has a workable official integration path. Most engineering teams can build against it directly. Open API: self-serve, documented, with SDKs
Kaltura is an enterprise video platform (VPaaS, Video Platform as a Service) that bundles video hosting, transcoding, HLS/DASH streaming, a customizable HTML5 player, live streaming, low-latency real-time video, video portals (MediaSpace), webinars and virtual events, virtual classrooms, lecture capture, OTT/TV experiences, AI-powered transcription/captions/translation, and a new wave of 'Agentic Avatars' and AI Content Lab products for automated clipping, enrichment, and conversational video agents.
Vertical: enterprise video platform (horizontal SaaS, with deep specialization in higher education, corporate communications, and media/telecom). A higher-ed customer integrates Kaltura with their LMS (Canvas/Blackboard/Brightspace) so faculty can record lectures via Kaltura Capture or the Kaltura Classroom appliance, automatically transcode and caption them, and embed them in course pages with analytics back to the LMS gradebook.
Kaltura is one of the two or three default 'enterprise video' brands alongside Brightcove and Vimeo Enterprise, and is effectively the dominant lecture-capture / academic-video vendor in North American higher education (competing with Panopto and Mediasite).
Yes, for any higher-ed institution or large enterprise running Kaltura, it is the system of record for the entire video stack: source video files (lecture recordings, all-hands, webinars, training, marketing assets), every rendered HLS/DASH variant, captions and AI translations in dozens of languages, viewer-level engagement (play/pause/seek/heatmap data per user per entry), webinar registration and attendance data, virtual classroom session recordings and chat logs, MediaSpace channel/category configuration, LMS gradebook integration data (for academic lecture capture), access-control profile assignments, and DRM/entitlement data for OTT deployments.
Founded 2006 in New York by Ron Yekutiel, Michal Tsur, Eran Etam, and Shay David. Raised $116M in private funding (Goldman Sachs, Sapphire Ventures, Nokia Growth Partners, Intel Capital, others) before going public on NASDAQ as KLTR in July 2021.
Admin-secret-based session auth concentrates risk, any actor with the admin secret can impersonate any user, list/modify any entry, and pull any analytics; rotating the secret invalidates every issued session. No documented public rate limits on the REST API, VPaaS-API-Getting-Started/api-guidelines.html outlines best practices but does not publish numeric request-per-minute ceilings, so high-volume integrations hit throttling without warning.

Common alternatives include Brightcove, Vimeo Enterprise / OTT, Microsoft Stream (M365), Panopto, Mediasite (Sonic Foundry), YouTube (Google). 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.
