Pricing
CustomTabnine no longer offers a public free tier and is sold as two annual-subscription plans. The Code Assistant Platform costs $39 per user per month and includes AI code completions, in-IDE chat across leading LLMs, Atlassian Jira integration, flexible deployment (SaaS, VPC, on-prem, or air-gapped), zero code retention, SSO, and enterprise compliance (GDPR, SOC 2, ISO 27001). The Agentic Platform costs $59 per user per month and includes everything in the Code Assistant Platform plus autonomous coding agents, the Tabnine CLI, and the Enterprise Context Engine with unlimited codebase connections to Bitbucket, GitHub, GitLab, and Perforce. Usage is unlimited when customers bring their own on-prem or cloud LLM endpoint; using Tabnine-provided LLM access requires a reserved token consumption quota billed at the underlying LLM provider's price plus a 5% handling fee. A Headless Agents add-on for CI/CD use is priced separately. Exact quotes require contacting Tabnine sales, as pricing is not self-serve.
FreemiumJetBrains AI offers four tiers. AI Free is $0/month with 3 AI credits every 30 days, unlimited code completion via JetBrains' Mellum model, and local model support via Ollama or LM Studio, but excludes frontier models and Junie for sustained agentic work. AI Pro is $10/month (Individual) or $20/month (Business), with 10 AI credits per month. AI Ultimate is $30/month (Individual) or $60/month (Business), with 35 AI credits per month, including a $5 bonus over the plan price. AI Enterprise is custom-priced at roughly $60/user/month billed annually, adding organization-wide credit pooling and enterprise controls. Each AI Credit equals $1 USD, and unused top-up credits (purchased separately at $1 each) remain valid for 12 months, while unused monthly plan credits do not roll over. A 30-day AI Pro trial is available for new users. AI Pro is also bundled into JetBrains' All Products Pack and dotUltimate subscriptions.

Summary
Privacy-first AI coding platform with completions, chat, and agentic workflows
AI coding assistance built natively into every JetBrains IDE
Tabnine Pros & Cons
Pros
- Zero code retention and no training on customer code, a core differentiator for IP-sensitive organizations
- Flexible deployment including fully air-gapped installs for the most security-conscious industries
- Supports multiple leading LLMs and allows bring-your-own-model for unlimited usage
- Enterprise Context Engine grounds AI suggestions and agents in real organizational architecture and standards
- One of the earliest and most established AI coding assistants, with over a decade of product maturity
Cons
- No public free tier anymore; entry pricing starts at $39 per user per month with annual commitment
- Recent acquisition by Tricentis introduces uncertainty around long-term product direction and roadmap
- Enterprise-grade governance and air-gapped deployment options are geared toward larger organizations, more than solo developers need
- Full agentic workflows and the Context Engine require the higher $59/user/month Agentic Platform tier
JetBrains AI Assistant Pros & Cons
Pros
- Deep semantic project understanding via IntelliJ's existing static-analysis engine, not just open-file context
- Junie autonomous agent handles multi-file planning, implementation, and self-correction, including a dedicated Debug mode
- Works across a single subscription spanning 20+ JetBrains IDEs
- Supports local models via Ollama and LM Studio at zero credit cost
- Strong enterprise trust features including zero-data-retention policies and .aiignore support
Cons
- Locked into the JetBrains IDE ecosystem, so it offers no value for developers using VS Code or other editors
- Credit-based quota system can be confusing, and heavy Junie or Claude Agent use can exhaust monthly credits well before the billing period ends
- AI Pro's 10 monthly credits are reportedly consumed within about a week under heavy agentic use, pushing users toward costly top-ups ($1 per credit)
- Best suited to JVM languages (Java, Kotlin); completion quality is reportedly less consistent for other languages
- AI Free tier excludes frontier models and the Junie agent, limiting it mostly to a demo of completion features
