Lowkey Chat SDK review
A chat SDK with Signal Protocol encryption, but paid plans start at $249 per month.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Lowkey Chat SDK provides APIs, SDKs and UI components for adding real-time messaging to web and mobile applications. Its described use cases include social messaging, team collaboration and livestream chats. Direct and group conversations, replies, threads, reactions, media sharing, polls and moderation cover common in-app chat needs. Signal Protocol end-to-end encryption is a notable feature for teams whose product requires encrypted messaging. The SDK is offered for web, iOS and Android, with cloud deployment.
Pricing is organized around monthly active users. The Free Trial includes 100 MAU, 25 concurrent connections and community support, with no credit card required; it is a trial rather than an ongoing free plan. Starter 10K costs $249 per month and includes messaging essentials, basic moderation, ticketed support, and no member or channel limits. Pro 10K costs $349 per month and adds advanced messaging features to Starter. Enterprise offers a dedicated servers option and priority support, with competitive or volume pricing. Teams should compare the trial's limits with their expected usage before choosing a paid tier.
The feature set spans practical conversation tools and moderation controls: mute, ban, block and report actions, message pinning, typing and recording indicators, and announcements sit alongside chat and media sharing. Tenor integration supports GIFs, and webhooks are available for integrations. The product is a fit for teams prioritizing encrypted chat and a broad set of messaging features across web and mobile. It may be a poor match for a project that needs an ongoing free tier or a fixed, published Enterprise price; teams seeking only basic chat may also find its paid entry point difficult to justify.
