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 MailerSend?
The emails your app absolutely must deliver — invoices, password resets, order confirmations — are the ones you can least afford to land in spam. MailerSend is built for exactly those: an intuitive transactional email API and SMTP service focused on high deliverability and easy integration, so your critical messages actually arrive.
API or SMTP, your choice
MailerSend offers both a modern API and SMTP relay, giving you flexible integration options whether you want to call an API from your code or point an existing system at an SMTP endpoint. It supports SDKs across seven programming languages, so dropping it into your stack is straightforward. For developers, that flexibility plus clean tooling makes wiring up reliable transactional email quick rather than painful — it's a natural alternative to services like Resend.
Deliverability and scale
The whole point of a transactional email service is that messages reach the inbox, and MailerSend emphasizes high deliverability with a 99.5% uptime guarantee and 24/7 technical support. It scales from hundreds of emails to millions, so it grows with you from a small app to a high-volume product without forcing a migration. Multiple domain management and IP allowlisting for security round out the enterprise-readiness.
Not just for developers
MailerSend includes a drag-and-drop email template builder, so non-developers can design and manage the look of transactional emails without hand-coding HTML — a genuinely useful bridge between engineering and marketing. It also handles inbound email routing, letting your app receive and process incoming mail. It pairs well with multichannel tools like Courier for a complete messaging setup.
Transparent, scalable pricing
MailerSend's pricing is refreshingly clear and generous at the low end, which makes it easy to start small and only pay more as your volume genuinely grows.
Who it's for
MailerSend suits growing startups, small businesses, agencies, white-label resellers and enterprises that need reliable transactional email delivery across applications and scales.
Pricing
MailerSend is freemium with four tiers: Free (500 emails/month), Hobby ($7/month, 5,000 emails), Starter ($35/month, 50,000 emails) and Professional ($110/month), plus per-unit overage charges. That generous free tier makes it easy to start sending transactional email at no cost.
The drag-and-drop template builder deserves emphasis because it quietly solves a common team friction: normally, changing the wording or design of a transactional email means filing an engineering ticket and waiting. With MailerSend, marketing or product can update templates directly, freeing developers to focus on the plumbing while non-technical teammates own the content — a small division of labor that saves everyone time.
Bottom line: MailerSend is a developer-friendly transactional email API and SMTP service with high deliverability, a drag-and-drop template builder and a genuinely generous free tier — a reliable way to make sure your app's critical emails actually land.
