Best Zro alternatives in 2026 (free and paid)
Zro is a narrow product, and its limits show it. It serves only open-weight models, so quality is capped by those models. Pro ($20 per month) and Max ($60 per month) quote token totals as estimates, agent tool calls are billed per call on top, there is no free tier, and an account and API key are required.
Claude from Anthropic is an assistant for writing, analysis and coding; Pro is $20 per user per month and there is a free tier. Cursor is an AI code editor with agents and code review; Individual (Pro) is $20 per month on usage-based billing, with a free Hobby tier. GitHub Copilot offers completions, chat and agent features in editors, the terminal and GitHub, with Copilot Pro at $10 per user and a free tier. Devin Desktop (formerly Windsurf) has Pro at $20 per month and a free tier.
These are complete coding products rather than a private endpoint, so they do not replace Zro's zero-retention and EU or US routing.
"Better suited" below is based on documented features and pricing from our verified profiles, not on a head-to-head test. Prices are USD as published by each vendor.
Why people look beyond Zro (by MoonMath)
- Pro $20/mo and Max $60/mo are the paid tiers Heavy users pay monthly or buy usage packs
- Token totals are estimates, not fixed allowances Real monthly usage can differ from ~1B/~5B
- Agent tool calls are billed separately Search-heavy agents cost more than the plan price
Taken from the documented limitations in our Zro (by MoonMath) profile.
Zro (by MoonMath) and its alternatives at a glance
| Tool | Starting price | Free tier | Platforms | Main limitation |
|---|---|---|---|---|
| Zro (by MoonMath) (this page) | $5 (Starter credit) | No | API | Monthly plans cover estimated token totals, not fixed allowances, and agent tool calls (web search, fetch) are billed per call on top. |
| Claude | $20/mo (Pro) | Yes | Web, Desktop, Mobile, API | All plans have usage limits that reset on a schedule; the paid chat subscription does not include API access, which is billed separately per token. |
| Cursor | From $20/mo (Individual (Pro)) | Yes | Desktop | Hobby has only limited Agent requests, and usage beyond the included amount is billed on demand. |
| GitHub Copilot | $10/mo (Copilot Pro) | Yes | Web, Desktop, Mobile | Chat, agents, code review and CLI all draw from a monthly GitHub AI Credits allowance that varies by model and task, so heavy agent use can exhaust a plan mid-month and require paid extra usage or an upgrade. |
| Devin Desktop (formerly Windsurf) | $20/mo (Pro) | Yes | Desktop | Free plan has light agent quota and limited model availability; enterprise features require contact. |
