Eon is a cloud-based data foundation for backup, disaster recovery, and enterprise AI. It maps and classifies data across environments, ingests information from structured and unstructured sources, and applies access controls.

eSearch is a cross-platform Electron screenshot and screen-search application for Windows, Linux, and macOS. It combines screenshot capture and editing, color picking, drawing, scrolling capture in arbitrary directions, screen recording, pinning images on screen, OCR, translation, reverse image search, QR-code recognition, and screen translation. Its offline eSearch-OCR engine is based on PaddleOCR. Users can select text in a screenshot for recognition, paragraph or vertical-text processing, rotation-aware recognition, later editing and proofreading, and optional additional language models; online OCR services are also supported. OCR output can be sent to translation engines, while reverse image search can use Google, Baidu, or Yandex, and the application can connect to configurable multimodal-model interfaces. Screen translation creates a pinned window that replaces recognized text with translated text and can run on a timer. The application provides configurable shortcuts and tray operation, supports Windows, Linux, and macOS, and is distributed from its website, releases, Arch Linux AUR, and winget. It is released under GPL-3.0.

Elasticsearch is a distributed search and analytics engine, scalable data store, and vector database developed by Elastic. It stores and indexes structured or unstructured text, numerical, geospatial, log, and metric data as JSON documents, which clients submit and query through REST APIs or language clients. Documents are organized in indexes and data streams and become searchable in near real time; supported search modes include full-text, vector, and hybrid retrieval for applications such as logs, metrics, application performance monitoring, security analysis, and retrieval-augmented generation. It can be used as a managed deployment through Elastic Cloud or installed and operated independently. The repository also documents a Docker-based local setup with Elasticsearch and Kibana for development and testing, and Kibana provides tools for exploring indexed data, filtering it, and creating visualizations and dashboards.

E2B is open-source cloud sandbox infrastructure for securely running AI-generated or user-specific code, tools, and agents in isolated environments. Sandboxes can be started and controlled through JavaScript/TypeScript or Python SDKs, supporting command execution, code interpretation, desktop interaction, sandbox templates, and snapshots that preserve a running environment's filesystem and memory for pausing and resuming. The platform manages sandbox lifetimes, idle timeouts, workspace assignment, runtime filesystem writes, storage, orchestration, and network restrictions. It can be self-hosted using Embed deployment and Terraform on AWS, Google Cloud, Azure, or a general Linux machine.

Inventory is a menu-bar application that indexes and lets users search local AI and IDE conversation histories (for tools such as Cursor, Claude Code, Zed, Codex, Kiro and Antigravity). It stores data locally, requires no signup or cloud account, and is offered for a one-time fee.
