The application comes as a self-contained binary file of about 15 MB, requiring no installation of JVM, Docker, or launching of server components. The project code is written in Go and TypeScript and is distributed under the MIT license. Builds are prepared for macOS (Intel and Apple Silicon), Windows, and Linux.    <\/p>\n<p>Unlike existing web-oriented tools like Kafka UI and AKHQ that require deploying a server process in Docker, kafkalet operates as a regular desktop application \u2014 similar to DBeaver or DataGrip for databases. The only desktop Kafka client until now had been Offset Explorer (formerly Kafka Tool), which was written in Java and has not been updated for a long time. The kafkalet application is built on the Wails v2 framework, combining a Go backend with a web interface in React 18, TypeScript, and shadcn\/ui into a single native binary. It uses the franz-go library for interacting with Kafka, implemented in pure Go without relying on librdkafka and CGO.    <\/p>\n<p>Main Features:  <\/p>\n<ul>\n<li class=\"l\"> A profile system for managing multiple environments (production, staging, dev). Each broker in the profile can have several named accounts with the ability to quickly switch between them. Passwords and tokens are stored exclusively in the OS's system secret storage (macOS Keychain, Windows Credential Manager, libsecret on Linux) and are not written to configuration files.\n<li class=\"l\"> Observer mode \u2014 reading messages from a topic without connecting to a consumer group, without committing offsets, and without side effects on the cluster. A separate Consumer mode allows connecting to a group and manually committing offsets.\n<li class=\"l\"> Time navigation (seek to timestamp) \u2014 jump to messages at a specified date and time without needing to manually calculate offsets. Support for authentication methods: SASL PLAIN, SCRAM-SHA-256, SCRAM-SHA-512, OAUTHBEARER (static token and client credentials flow), TLS with certificate verification. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/server\/dts-los-angeles\/\" title=\"server\" data-wpil-keyword-link=\"linked\">server<\/a>, mTLS (mutual authentication via certificates).\n<li class=\"l\"> Streaming message viewing with regex filtering by keys and values in real-time. Simultaneous monitoring of multiple topics in separate tabs is supported. Virtualization of the list allows displaying over 50,000 messages without performance degradation.\n<li class=\"l\"> Topic management: creation, deletion, modification of configuration parameters, viewing partitions, leaders, and set of in-sync replicas (ISR).    <img decoding=\"async\" alt=\"Release of kafkalet 0.1, a desktop client for Apache Kafka.\" src=\"\/wp-content\/uploads\/2026\/03\/7378d7abb0b3e27887cf6a6d9a492ccf.png\" style=\"display:block;margin: 0 auto\" \/>\n<li class=\"l\"> Management of consumer groups: viewing lag by partitions, resetting offsets to earliest, latest, or a specific timestamp, viewing group members (client ID, host, assigned topics), deleting groups.\n<li class=\"l\"> Sending messages with specified key, value, headers, and target partition.    <img decoding=\"async\" alt=\"Release of kafkalet 0.1, a desktop client for Apache Kafka.\" src=\"\/wp-content\/uploads\/2026\/03\/6c8d56bd8b770526b09e2a983012e95a.png\" style=\"display:block;margin: 0 auto\" \/>\n<li class=\"l\"> Organizing topics: pinning frequently used topics, grouping into named folders, searching with support for regular expressions and filtering by minimum number of partitions.\n<li class=\"l\"> Exporting message buffer in JSON or CSV format.\n<li class=\"l\"> Integration with Confluent Schema Registry for automatic decoding of messages in Avro format.\n<li class=\"l\"> JavaScript plugin system for custom decoding of messages (Protobuf, MessagePack, and other formats).\n<li class=\"l\"> Importing and exporting settings in JSON format, including profiles, topic groups, and pinned topics.  <\/ul>\n<p>Source: <a rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=64916\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043d \u0432\u044b\u043f\u0443\u0441\u043a kafkalet 0.1, \u0434\u0435\u0441\u043a\u0442\u043e\u043f\u043d\u043e\u0433\u043e \u0433\u0440\u0430\u0444\u0438\u0447\u0435\u0441\u043a\u043e\u0433\u043e \u043a\u043b\u0438\u0435\u043d\u0442\u0430 \u0434\u043b\u044f \u0440\u0430\u0431\u043e\u0442\u044b \u0441 Apache Kafka. \u041f\u0440\u0438\u043b\u043e\u0436\u0435\u043d\u0438\u0435 \u043f\u043e\u0441\u0442\u0430\u0432\u043b\u044f\u0435\u0442\u0441\u044f \u0432 \u0432\u0438\u0434\u0435 \u0441\u0430\u043c\u043e\u0434\u043e\u0441\u0442\u0430\u0442\u043e\u0447\u043d\u043e\u0433\u043e \u0431\u0438\u043d\u0430\u0440\u043d\u043e\u0433\u043e \u0444\u0430\u0439\u043b\u0430 \u0440\u0430\u0437\u043c\u0435\u0440\u043e\u043c \u043e\u043a\u043e\u043b\u043e 15 \u041c\u0411, \u043d\u0435 \u0442\u0440\u0435\u0431\u0443\u0435\u0442 \u0443\u0441\u0442\u0430\u043d\u043e\u0432\u043a\u0438 JVM, Docker \u0438\u043b\u0438 \u0437\u0430\u043f\u0443\u0441\u043a\u0430 \u0441\u0435\u0440\u0432\u0435\u0440\u043d\u044b\u0445 \u043a\u043e\u043c\u043f\u043e\u043d\u0435\u043d\u0442\u043e\u0432. \u041a\u043e\u0434 \u043f\u0440\u043e\u0435\u043a\u0442\u0430 \u043d\u0430\u043f\u0438\u0441\u0430\u043d \u043d\u0430 Go \u0438 TypeScript \u0438 \u0440\u0430\u0441\u043f\u0440\u043e\u0441\u0442\u0440\u0430\u043d\u044f\u0435\u0442\u0441\u044f \u043f\u043e\u0434 \u043b\u0438\u0446\u0435\u043d\u0437\u0438\u0435\u0439 MIT. \u0421\u0431\u043e\u0440\u043a\u0438 \u043f\u043e\u0434\u0433\u043e\u0442\u043e\u0432\u043b\u0435\u043d\u044b \u0434\u043b\u044f macOS (Intel \u0438 Apple Silicon), Windows \u0438 Linux.
