APIs & SDKs

Every SaaS team builds the same integration code. Your signup event needs to reach HubSpot. Your payment failure needs to alert Salesforce. Your cancellation needs to trigger Intercom. So engineering teams write custom handlers, add retry logic, debug silent failures at 3am, and maintain it all forever — for every new destination, on every new product feature. Meshes replaces that entire layer. Emit one product event through the Meshes SDK or REST API, and we route it to every connected destination simultaneously — with automatic retries (exponential backoff + jitter), idempotent delivery, dead letter queues, and full event replay. Your app owns the product logic. Meshes owns the delivery machinery around it. Integrations include HubSpot, Salesforce, Intercom, Mailchimp, ActiveCampaign, SendGrid, Slack, Discord, Resend, Zoom, AWeber, MailerLite, and custom webhooks with HMAC signing and configurable auth schemes. **Built for multi-tenant SaaS.** Each customer, environment, or region gets an isolated workspace with its own connections, rules, credentials, and limits. OAuth tokens, API keys, and refresh cycles are handled per workspace so tenant boundaries stay clean — no more hand-rolled credential plumbing scattered across tables, flags, and env vars. **Embeddable customer workspaces.** White-label integration UIs let your users connect, configure, and monitor their own integrations directly inside your product. Mint a session, mount the launch URL in an iframe, and your customers get a full integration experience under your brand. JWT-based auth with claims-based permissions. **Not a workflow automation tool.** Meshes is infrastructure underneath tools like Zapier, n8n, or Make — not a replacement for them. Use it when you need reliable delivery guarantees, per-tenant isolation, and observability that visual workflow builders can't provide.

Usernames often look like a small implementation detail when you’re building a product. You add a uniqueness check, maybe block a couple of obvious cases like admin, and move on. But as products grow, usernames quietly turn into a real problem. People register admin, support, or system. Brand and impersonation-prone usernames slip through. Short or high-value handles get taken early. To fix it, teams start maintaining internal “reserved username” lists that keep growing over time. What began as a simple array slowly becomes brittle logic, scattered rules, and long-term tech debt. username.dev exists to solve that problem properly. It’s a focused, API-first service that helps apps govern usernames from day one. Instead of hardcoding rules or constantly patching edge cases, teams can rely on a single API to detect and block reserved, premium, or risky usernames during signup. The goal isn’t just validation — it’s prevention. Username.dev helps reduce impersonation risk, protect high-value handles, and keep internal roles and system names out of user hands, before issues show up in production. This project grew out of firsthand experience maintaining messy username rules across multiple products. Rather than every team reinventing their own approach, username.dev provides a clean, maintainable way to treat username governance as a first-class concern. It’s built for developers, indie founders, and teams working on social apps, marketplaces, communities, or any platform where usernames matter. Whether you’re launching something new or scaling an existing product, username.dev helps you avoid future headaches — and the tech debt that comes with them.
