IsDown was built out of frustration at 4 AM. Nuno Tomas, founder and on-call engineer, spent 30 minutes debugging an alert before realising the cloud provider had an outage posted on their status page, but nobody was watching it. That night, he decided there had to be a better way.
Today, IsDown monitors 6,000+ cloud and SaaS services, has performed over 1 billion status checks, has detected 520,000+ outages, and has sent 5.2 million+ notifications. Trusted by IT, DevOps, and engineering teams since 2020.
What makes IsDown different: it reads official vendor status pages directly, not just crowdsourced reports. Combined with early detection signals, it catches outages before vendors acknowledge them, sometimes hours ahead. In January 2026 alone, IsDown detected 101 incidents that vendors never officially reported.
Key capabilities: - Monitor 6,000+ services from one dashboard. Filter by service, component, or severity. - Get alerts within seconds in Slack, PagerDuty, Datadog, Microsoft Teams,ย Incident.io, FireHydrant, Grafana, Discord, SMS, and wherever your team works. - Track scheduled maintenance across all vendors in a live feed and calendar, so nothing slips through unnoticed. - Create public or private hosted status pages with your own domain and branding. - Monitor your own APIs, endpoints, and SSL certificates from US, EU, and Asia. - Built for enterprise: SSO (SAML, OAuth), SOC 2 Type II in progress, MCP Server for AI assistant queries.
Setup takes 5 minutes. No engineering required. 14-day free trial, no credit card needed.

CleverTools.inIsDown.app's answer
IsDown monitors official vendor status pages directly, not just crowdsourced reports. This means alerts include real incident context: what broke, which components are affected, and real-time resolution status. Not just "something is down." Combined with crowdsourced early detection signals, IsDown can catch outages before vendors acknowledge them. In January 2026 alone, IsDown detected 101 incidents that vendors never officially reported. Every team monitoring cloud services already has uptime tools that ping their own URLs. IsDown tells you what is happening with the third-party services your stack depends on, before your users feel it.
CleverTools.in's answer:
India-first, not India-as-an-afterthought. Most online tool sites bolt on a generic tax calculator. CleverTools is built around the actual Indian financial year โ FY 2025-26 New Regime slabs with the โน12L Section 87A rebate, post-Budget 2024 capital-gains rates (STCG 20% / LTCG 12.5% / โน1.25L equity exemption), Section 211 advance-tax instalment schedule with Section 234C interest exposure, and 14 state-wise Professional Tax slabs. Hindi long-tail keywords (gratuity kaise calculate kare, marginal relief kya hai) baked into SEO.
Details every other calculator misses.
Surcharge calculator with automatic marginal relief (most tools and even some return-prep software ignore it โ costs โน2-15 lakh near band thresholds) Leave Encashment with the full Section 10(10AA) four-limit rule AND the lifetime โน25L cap tracked across employers Gratuity with both formulas (15รท26 covered / 15รท30 not-covered) + 5-year-OR-4y240d eligibility (Madras HC Mettur Beardsell ruling) Salary Slip with the statutory โน1,800 PF cap (12% ร โน15,000 ceiling) auto-applied 3. 100% browser-based โ files never leave your device. No server uploads. Your salary, PAN, GSTIN, bank account, PDFs โ all processed locally with pdf-lib, jsPDF, pdfjs-dist. Works offline after first load.
Tool depth, not link-farm breadth. 80+ tools, but each ships with 4-6 features, 3-4 how-it-works steps, 4-8 FAQs (which generate Google FAQ rich snippets), and 30+ targeted keywords. Compare to most competitors where the "calculator" is a single input + result.
Receipt/document generators that actually match Indian payroll/compliance formats.
Salary Slip with 3 templates (Classic Grid / Modern / Minimal), live PDF preview, full WD/WO/PH/PD/CL/PL/SL/LWP working-days breakdown, Actual + Payable columns with auto-prorate on LWP Rent Receipt with sequential numbering, payment-mode line, revenue-stamp prompt above โน5,000, mandatory landlord-PAN warning above โน1L/year GST Invoice with auto CGST+SGST vs IGST routing, 5 tax slabs, reverse charge, e-way bill, HSN autocomplete 6. No signup wall, no rate limits, no watermarks. Free tools that stay free โ even with file uploads.
Modern stack & performance. Next.js 16 + Turbopack, Tailwind 4, strict TypeScript, full dark-mode parity, 156 prerendered pages, dynamic imports per tool so each route ships only what it needs.
Honest math, transparent reasoning. Calculator outputs explain why โ which limit kicked in, which slab applies, why marginal relief was/wasn't triggered. Not a black box.

Three reasons:
Accuracy on the details that cost real money. Marginal relief, the โน1,800 statutory PF cap, the four-limit rule for leave encashment, the 4y-240d gratuity eligibility ruling โ most calculators miss these and quietly cost users โน2โ15 lakh. CleverTools applies them automatically and explains which limit kicked in. Privacy by architecture. Your PAN, GSTIN, salary, bank account, PDFs โ they are processed in your browser using pdf-lib and jsPDF. Nothing is uploaded. Works offline after the first visit. Free, fast, no friction. 80+ tools, no login wall, no rate limits, no watermarks on PDFs. Each tool is a single static page โ no spinning loaders, no "buy premium" interstitials.

Customers span SaaS companies, schools, DevOps agencies, and enterprise IT teams across industries.

IsDown.app's answer
IsDown was built out of frustration at 4 AM. Nuno Tomas, the founder, was on-call when a PagerDuty alert woke him up. After 30 minutes of debugging, he realised the problem was not his code. It was the cloud provider. They had posted an outage on their status page, but nobody on the team was watching it. That night, he decided there had to be a better way. He built the first version of IsDown so his team would never be the last to know about a vendor outage. Founded in 2020, IsDown has since grown to monitor 6,000+ services, perform over 1 billion status checks, detect 520,000+ outages, and send 5.2 million+ notifications. The same problem Nuno solved for his team that night is now solved for IT, DevOps, and engineering teams around the world.

CleverTools was started by Milan Bagiya out of frustration with the state of online Indian tax calculators โ most were either ad-laden link farms with wrong formulas, or behind โน999/month paywalls. The premise was simple: build a focused, free, India-first tool suite where the math actually reflects current law (post-Budget 2024 reforms, latest CBDT notifications), where files never leave the user's browser, and where every calculator explains why its answer is what it is. It started with PDF and image utilities; the financial calculator suite (Income Tax, HRA, Gratuity, Capital Gains, Advance Tax, Surcharge, Professional Tax, Leave Encashment) is the current focus โ each one researched against actual sections of the Income-tax Act and Indian state-level rules.
