AI Coding Assistants: Pricing, Billing Models & Deployment — 2026
AI coding tools are repricing faster than almost any software category — usage-based, credits, quotas, all in flux. This compares the major assistants in 2026 on how they bill, what's still free, and how they deploy (cloud vs air-gapped).
Between mid-2025 and 2026, nearly every major AI coding assistant changed its billing model. For developers and engineering managers, the relevant questions are: what does the entry plan actually include, is it credits/usage or flat, and can it run in a private/air-gapped environment? This page maps that.

The comparison
| Tool | Billing model (2026) | Free tier | Notable |
|---|
| GitHub Copilot | Usage-based (AI Credits) from Jun 1, 2026; completions/Next Edit stay included (don't consume credits) | Yes (Free $0) | Business includes $19/mo, Enterprise $39/mo in AI Credits; IP indemnity |
| Cursor | Credit-based since Jun 2025; each paid plan's credit pool = its dollar price | Yes (Hobby $0) | Auto mode unlimited on paid; premium frontier models draw from credits |
| Windsurf | Overhauled Mar 2026: daily/weekly quotas (replaced credits) | Yes — unlimited autocomplete on free | Add-on credits $10 per 250 units, no longer expire; Cognition (Devin) acquired it in 2025 |
| Replit | Subscription + usage credits (Core $20/mo incl. $20 credits) | Yes (Starter $0) | Agent generates/debugs/deploys; Economy/Power modes; Pro plan (Feb 2026) |
| Tabnine | Flat per-user ($39/user/mo annual); enterprise-only since Apr 2, 2025 | No (free tier removed) | Air-gapped/on-prem/VPC/SaaS; SOC 2 Type II; zero code retention |
Key findings
- This is the fastest-repricing software category right now. Cursor moved to credits (Jun 2025), Tabnine went enterprise-only (Apr 2025), Windsurf replaced credits with quotas (Mar 2026), and GitHub Copilot shifts to usage-based AI Credits (Jun 1, 2026). Any pricing comparison older than a few months is likely wrong — check the date.
- "Free" usually means autocomplete, not the agent. The included/free layer is typically code completion (Copilot keeps completions out of credit consumption; Windsurf gives unlimited autocomplete free), while the expensive part — agentic, multi-file, frontier-model work — draws from credits or a paid tier. Budget for the agent, not the autocomplete.
- Credits vs quotas vs flat is a real trade-off. Credits (Cursor, Copilot) scale cost with usage; quotas (Windsurf, post-Mar 2026) cap usage per day/week; flat per-seat (Tabnine) is predictable but enterprise-priced. Heavy users and finance teams will prefer different models — match it to your usage pattern.
- Privacy/deployment is where Tabnine stands alone here. Tabnine runs fully air-gapped on your own infrastructure with zero code retention (SOC 2 Type II) — the option for regulated or IP-sensitive teams that can't send code to a cloud model. It traded the free tier for that enterprise positioning.
- IP indemnity is a procurement checkbox now. GitHub Copilot markets IP indemnity — relevant for enterprises worried about generated-code provenance, the same concern driving commercial indemnification in AI image tools (see our AI generator study).
Methodology
Five widely-used AI coding assistants compared on 2026 billing model (usage-based, credits, quotas, flat), free-tier availability, and deployment/privacy options, from a sourced dataset. Dates reflect announced pricing changes. This is a billing-and-deployment map, not a code-quality benchmark; model quality and IDE fit also matter and change rapidly.
Editorial note (verification): AI coding tool pricing is among the fastest-changing in software. Confirm the current billing model, credit/quota amounts and free-tier status on the vendor's pricing page before relying on this. Compiled 2026-06-27.
