IBM Cloud's free tier (Lite plan) includes Watson AI services (NLP, Speech-to-Text, Tone Analyzer), a free Kubernetes cluster (1 worker node), 256MB Cloud Foundry runtime, 500MB Cloudant NoSQL storage, and IBM Cloud Object Storage (25GB free). No credit card required for Lite tier.
IBM Cloud's free tier, called the Lite plan, is unique among major cloud providers because it does not require a credit card to access. IBM provides a meaningful set of services at no cost under the Lite plan, particularly focused on their Watson AI and developer tooling services. Understanding what is included helps you determine when the free tier is sufficient and when a purchased account makes more sense.
Watson AI services are IBM Cloud's flagship free offering. Under the Lite plan, Watson Assistant (formerly Watson Conversation) provides 10,000 API calls per month for building chatbots and virtual assistants. Watson Natural Language Understanding offers 30,000 NLU items per month for extracting text entities, relationships, and sentiment. Watson Speech to Text includes 500 minutes per month of audio transcription, and Watson Text to Speech provides 10,000 characters per month of text-to-audio conversion. These are genuine, usable amounts for development and small-scale production applications — IBM is more generous with AI service free tiers than most competitors.
IBM Cloud Kubernetes Service under the Lite plan provides a single-zone free cluster with one worker node running on shared hardware. This is enough to run small containerized applications and learn Kubernetes without any cost. The cluster is deleted after 30 days of inactivity, so you need to actively use it. For persistent Kubernetes workloads, you would upgrade to a paid cluster.
Cloud Foundry runtime (an IBM-managed PaaS) provides 256MB of runtime memory free per month — enough to run a small Node.js or Python application. IBM Cloudant NoSQL database includes 1GB of storage and 20 provisioned throughput capacity on the Lite plan. IBM Cloud Object Storage includes 25GB of regional storage free, which is competitive with AWS S3's free tier.
The limitations of the IBM Lite plan become apparent for production workloads: no Virtual Server Instances (IBM's equivalent of EC2), no persistent block storage, limited network egress, and service quotas that are quickly exceeded in real applications. Our IBM Cloud free trial account ($30) provides the same Lite access plus our 7-day replacement guarantee, and our IBM port 25 open account ($80) unlocks SMTP capabilities — ideal for businesses that need IBM's enterprise reputation for email deliverability.
