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.
FreeAider itself is completely free and open source under the Apache 2.0 license, with no subscription, tiers, or usage limits imposed by the project. Costs come entirely from the LLM provider a developer chooses to connect: for example, Anthropic, OpenAI, or DeepSeek API usage is billed directly by that provider at its own per-token rates, or developers can run local models through Ollama at no cost at all. Because there is no Aider-specific markup or platform fee, effective cost is determined by model choice and usage volume rather than by Aider itself.

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
Aider Pros & Cons
Pros
- Completely free and open source, with no platform markup on top of LLM provider API costs
- Deep git-native workflow makes every AI change individually reviewable, diffable, and reversible
- Model-agnostic support for 100+ LLM providers, including local models, avoids vendor lock-in
- Efficient repo mapping keeps large codebases manageable without dumping entire files into context
- Transparent, actively maintained public leaderboard helps developers pick the best-performing model for real coding tasks
Cons
- Terminal-only interface has a learning curve for developers used to GUI-based tools like Cursor or Copilot
- No bundled AI access; users must bring their own API keys and manage separate billing with LLM providers
- Deliberately not a fully autonomous agent, staying one step behind tools like Devin that run unsupervised for longer stretches
- No official enterprise support tier or SLA, since the project is community-maintained open source
