What is DEVRlAN?
DEVRlAN is a privacy-first browser workspace built for developers who need fast, practical utilities for everyday technical tasks.
Instead of switching between multiple websites, developers can use a focused collection of browser-based tools in one place. DEVRlAN includes utilities for JSON formatting and validation, JWT debugging, Base64 encoding and decoding, UUID generation, Regex testing, URL encoding, hashing, and other common developer workflows.
Privacy is a core part of the product. Whenever possible, processing happens locally in the browser rather than sending sensitive input to a remote server. This makes DEVRlAN useful for developers working with data they may not want to upload to third-party services.
The platform is free to use and does not require an account or installation. Developers can open a tool, complete the task, and return to their work without setting up another service.
DEVRlAN is an independent developer project focused on useful browser-native utilities, simple workflows, and privacy-conscious design.
What problem it solves
Developers often switch between multiple websites for small technical tasks such as formatting JSON, decoding Base64, inspecting JWTs, generating UUIDs, testing Regex, encoding URLs, and hashing data. DEVRlAN brings these everyday utilities into one browser workspace, reducing unnecessary tool switching while keeping sensitive processing local whenever possible.
Alternatives & competitors
DEVRlAN is an alternative to using separate online developer utilities for individual tasks. It focuses on bringing common browser-based utilities into one privacy-conscious workspace, with local processing whenever possible.
What is E2B?
The moment you let an AI agent actually run code, you have a serious problem: you can't just execute arbitrary AI-generated code on your own servers and hope for the best. E2B solves exactly that — it provides open-source, isolated cloud sandboxes where AI agents can securely execute code and use real-world tools, safely walled off from everything else.
A safe place for agents to run code
E2B gives AI agents isolated sandbox environments to run Python, JavaScript and other languages inside microVM-based containers powered by Firecracker technology (the same isolation tech behind serverless platforms). That means an agent can write and execute code, install packages, read and write files, and use a terminal — all without any risk to your infrastructure. For anyone building agentic AI, that secure execution layer is a foundational, hard-to-build-yourself piece.
Fast and long-running
Performance is a big deal for agent workflows, and E2B delivers sub-200ms startup times so spinning up a sandbox doesn't bottleneck your agent, plus support for sessions up to 24 hours for longer, stateful tasks. It integrates with major LLM providers including OpenAI, Anthropic, Mistral and Meta's models, so it drops into whatever AI stack you're using. It pairs naturally with vector databases like Weaviate and Qdrant in the broader agent infrastructure toolkit.
Built for real agent use cases
E2B is designed for the workloads people are actually building: deep-research agents, data-analysis tools, coding assistants and reinforcement-learning systems. Anywhere an AI needs to genuinely do things — run a calculation, execute a script, manipulate files — rather than just talk, E2B is the safe environment where that happens.
Open and enterprise-ready
Being open source means transparency and the option to inspect or self-host, while the platform is built to enterprise-grade standards for companies deploying agents in production. That combination is increasingly what serious AI teams look for.
Who it's for
E2B suits enterprise companies, AI startups and developers building agentic workflows — anyone whose AI needs to execute code and use tools securely rather than merely generate text.
Pricing
E2B is freemium with paid tiers (including a Pro plan) for heavier usage; you can start free to build and test your agents' code execution before scaling up. Being open source, self-hosting is also on the table for teams that want full control.
Bottom line: E2B is the secure, open-source sandbox layer for AI agents — fast, isolated microVMs where agents can safely run code and use real tools, making it foundational infrastructure for anyone building serious agentic applications.
