Over the last months I've been building a handful of focused SaaS products on the side, each solving a problem I ran into at work:</p> <ul> <li> <strong>MRRLens</strong> (<a href="https://mrrlens.com" rel="noopener noreferrer">mrrlens.com</a>) shows verified revenue, recurring complaints and buyer intent for SaaS products, apps and plugins. I use it to decide what's worth building.</li> <li> <strong>Attrelix</strong> (<a href="https://attrelix.com" rel="noopener noreferrer">attrelix.com</a>) is an API that flags fake signups: disposable emails, Gmail aliases, datacenter IPs and bots.</li> <li> <strong>CVnify</strong> (<a href="https://cvnify.com" rel="noopener noreferrer">cvnify.com</a>) tailors a resume to a specific job description so it gets through applicant tracking systems.</li> <li> <strong>Vexquota</strong> (<a href="https://vexquota.com" rel="noopener noreferrer">vexquota.com</a>) tracks sales commissions with tiers, splits and clawbacks, and generates statements per rep.</li> <li> <strong>AlertWard</strong> (<a href="https://alertward.com" rel="noopener noreferrer">alertward.com</a>) keeps SSL certificates, domains and licenses in one place, per client, and alerts before anything expires.</li> </ul> <p>All have a free tier. Feedback is welcome, especially on pricing and what feels missing.</p> saas showdev sideprojects devops
