cloudless database for realtime apps.
Realtime database, runs anywhere. Install Fireproof in your front-end app or edge function, and sync data via any backend.
Add collaboration to any app with Fireproof. Access data from JavaScript servers and edge functions. Use live queries to update your UI automatically when the ledger changes. Connect realtime sync and those changes will sync between browsers and backend functions. Apps built this way are multi-player by default.
The realtime client-side database.
Instant is a client-side database that makes it easy to build real-time and collaborative apps like Notion or Figma.
the open-source database for the realtime web.
RethinkDB pushes JSON to your apps in realtime.
RethinkDB is the first open-source scalable database built for realtime applications. It exposes a new database access model, in which the developer can tell the database to continuously push updated query results to applications without polling for changes. RethinkDB allows developers to build scalable realtime apps in a fraction of the time with less effort.
Real-time HTTP Intrusion Detection.
teler is an real-time intrusion detection and threat alert based on web log that runs in a terminal with resources that we collect and provide by the community. ❤️
Sync for modern apps. The standard sync layer for local-first apps. Build reactive, realtime, local-first apps directly on Postgres.
ElectricSQL is a local-first software platform that makes it easy to develop high-quality, modern apps with instant reactivity, realtime multi-user collaboration and conflict-free offline support.
Local-first is a new development paradigm where your app code talks directly to an embedded local database and data syncs in the background via active-active database replication. Because the app code talks directly to a local database, apps feel instant. Because data syncs in the background via active-active replication it naturally supports multi-user collaboration and conflict-free offline.

Market leading RTOS (Real Time Operating System) for embedded systems with Internet of Things extensions. Real-time operating system for microcontrollers?
Developed in partnership with the world’s leading chip companies over an 18-year period, and now downloaded every 170 seconds, FreeRTOS is a market-leading real-time operating system (RTOS) for microcontrollers and small microprocessors. Distributed freely under the MIT open source license, FreeRTOS includes a kernel and a growing set of IoT libraries suitable for use across all industry sectors. FreeRTOS is built with an emphasis on reliability and ease of use.
The Zephyr® Project is an open source scalable real-time operating system (RTOS) supporting multiple hardware architectures including ARC, ARM, RISC-V and X86. The Zephyr OS is a proven RTOS used in products today.
Zephyr OS is modular and supports multiple architectures, developers can easily tailor an optimal solution to meet their needs. Zephyr OS is used in a broad spectrum of applications from simple connected sensors to complex edge systems.
Fast real-time compression algorithm.
Zstandard, or zstd as short version, is a fast lossless compression algorithm, targeting real-time compression scenarios at zlib-level and better compression ratios. It's backed by a very fast entropy stage, provided by Huff0 and FSE library.
Zstandard is a fast compression algorithm, providing high compression ratios. It also offers a special mode for small data, called dictionary compression. The reference library offers a very wide range of speed / compression trade-off, and is backed by an extremely fast decoder (see benchmarks below). Zstandard library is provided as open source software using a BSD license. Its format is stable and published as IETF RFC 8878.
ClickHouse® is a free analytics DBMS for big data.
ClickHouse® is an open-source column-oriented database management system that allows generating analytical data reports in real-time.
Mercure is an open protocol for real-time communications designed to be fast, reliable and battery-efficient. It is a modern and convenient replacement for both the Websocket API and the higher-level libraries and services relying on it.
