Pricing
FreemiumZed offers three tiers. Personal is $0 forever, including 2,000 accepted edit predictions per month and unlimited use with your own API keys or external agents like Claude Agent and Codex CLI. Pro is $10/month with unlimited edit predictions, $5 of included tokens, and usage-based billing beyond that at API list price plus 10%, billed either at month-end or per $10 of overage incurred, whichever comes first; a two-week free trial with $20 of token credits is available (Anthropic's Opus models are excluded from the trial). Business is $30 per seat per month with no minimum seat count, adding org-wide AI model policies, data governance controls, role-based access controls, and unified spend visibility across the organization; order form contracts are available at 25+ seats. Business does not currently offer a free trial, and SSO, SAML, and SCIM are planned but not yet available.
FreemiumCodex has no standalone subscription; access is bundled into ChatGPT plans. Free ($0/month) includes limited trial access via a lighter Codex model with restricted daily limits. Go costs $8/month for light, local use only (no cloud task delegation). Plus costs $20/month and includes Codex on the web, CLI, IDE extension, and iOS, covering typical daily use. Pro splits into two tiers since April 9, 2026: Pro 5x at $100/month and Pro 20x at $200/month, offering 5x and 20x higher usage than Plus respectively. Business costs $20/user/month billed annually ($25/month billed monthly), with standard seats including Codex within usual plan limits; OpenAI stopped offering new pay-as-you-go Codex-only Business seats as of June 24, 2026, though existing seats continue working. Enterprise, Edu, and Gov plans use custom pricing. Since April 2, 2026, usage across Plus, Pro, and Business shifted from per-message limits to token-based credits (roughly $0.04 each), metered on a rolling 5-hour window plus a weekly cap; Enterprise, Edu, Health, and Gov plans moved to the same system on April 23, 2026. API-key usage bypasses ChatGPT plan credits entirely and bills directly at standard OpenAI API token rates. Real-world usage for active developers commonly runs $100 to $200 per month depending on model choice, parallel agents, and fast-mode usage.

Summary
A minimal, GPU-accelerated code editor built for speed and AI collaboration
OpenAI's autonomous coding agent for pull requests, refactors, and reviews
Zed Pros & Cons
Pros
- Exceptionally fast, GPU-accelerated Rust editor with near-instant startup and low input latency
- Free Personal plan allows unlimited AI usage with your own API keys at no extra cost to Zed
- Native real-time multiplayer collaboration built into the core editor, not a plugin
- Open Agent Client Protocol (ACP) lets developers bring virtually any agent or model into the editor
- Fully open source, so the codebase can be inspected, extended, and self-hosted
Cons
- Much smaller extension ecosystem (roughly 800) compared to VS Code's 50,000+
- No codebase-wide AI indexing like some competitors, limiting AI context to file-level and open project scope
- SSO, SAML, and SCIM are planned but not yet available, limiting appeal for larger regulated enterprises
- Pro's $5 included token credit is modest and can be exceeded quickly with heavy agentic use, triggering usage-based billing
- Business plan has no free trial, unlike the Pro plan's two-week trial
OpenAI Codex Pros & Cons
Pros
- Bundled into existing ChatGPT plans, so many users already have some level of access at no extra cost
- Consistent agent experience across ChatGPT, IDE, CLI, and desktop, all tied to one account
- Parallel agents and built-in cloud sandboxes let teams tackle multiple engineering tasks simultaneously
- Skills system lets teams encode their own standards so Codex needs less supervision over time
- Backed by OpenAI's frontier coding models and adopted by engineering teams at companies like Duolingo, Ramp, and Cisco Meraki
Cons
- Token-based credit pricing (since April 2026) makes monthly costs harder to predict than flat per-seat pricing
- Heavy parallel or fast-mode usage can push real spend to $100 to $200 per developer per month even on mid-tier plans
- The Codex brand has been recycled and repositioned multiple times since 2021, which can create confusion about what current Codex actually is
- No standalone subscription; access is entirely tied to a ChatGPT plan rather than a dedicated developer product
