Every SaaS startup needs a toolkit of applications covering communication, project management, development, analytics, marketing, finance, and more. Below are 20 top-rated SaaS-friendly tools for 2026, each with a brief use-case, pricing overview, and alternatives. These tools emphasize startup-friendliness – they offer free tiers or scalable pricing, and many are popular both in India and globally.

1. Slack (Team Communication) – A leading chat platform for teams.
   
   Use-case: real-time messaging, channels for projects, and file sharing. Slack’s free plan is generous (access to last 90 days of messages, 1:1 voice/video calls). Paid plans ($6.67–$12.50/user/mo) add unlimited history, group calls, and shared channels. Many startups prefer Slack due to its app ecosystem.
   
   Alternatives: Microsoft Teams (especially if you use Office 365), Discord (popular with dev communities). Notably, 70% of Indian unicorns use Slack, highlighting its prevalence.
   
   

2. Zoom (Video Conferencing) – Ubiquitous for remote meetings, webinars, and demos.
   
   Use-case: virtual team meetings and customer calls. Zoom’s free tier allows unlimited 1:1 calls and 40-minute group meetings. Paid plans (~$14.99–$19.99/month/host) lift time limits and add admin features.
   
   Alternatives: Google Meet (now free with Google Workspace) or Microsoft Teams (video + chat). Zoom is noted for its ease of use and reliability.
   
   

3. Google Workspace (Collaboration Suite) – Includes Gmail, Docs, Sheets, Drive, etc.
   
   Use-case: email, document collaboration, file storage. Affordable for startups: $6/user/month for Business Starter. It centralizes communication and is globally available.

4. GitHub (Code Hosting & Collaboration) – The most popular code repository.
   
   Use-case: Git-based source control, collaboration via pull requests, issue tracking, CI/CD (GitHub Actions).

   Alternatives: PayPal (ubiquitous but less developer-friendly), Braintree. For Indian businesses, integrate Stripe plus a local provider – see Razorpay next.
   
   

8. Razorpay (India Payments) – Leading Indian payment gateway.
   
   Use-case: accept INR payments via cards, UPI, wallets. Razorpay has no monthly fee for basic plan (just transaction charges). It simplifies Indian compliance (GST, payout rules). Razorpay provides subscription billing and automates recurring UPI mandates.
   
   Alternative: Instamojo (simpler for quick setup), Paytm Payment Gateway. Razorpay is ideal for startups targeting India as it “covers 100% of how India pays”.
