Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
CodeSandbox
- Detailed paid plan pricing was not published on the accessible pages, making cost comparison difficult.
- Focus has shifted toward programmatic sandbox infrastructure, which may be less approachable for casual users just wanting a quick online editor.
- Public sandboxes are visible to others by default, which is not ideal for proprietary code.
Perplexity
- Context window has been stealthily reduced despite prior claims of 1-million-token capacity
- Citations sometimes point to irrelevant or overly general articles that do not support the stated claims
- Weak performance on complex multi-step reasoning and deep logic compared to dedicated reasoning LLMs
- Web crawler ignores robots.txt directives and scrapes content from sites that explicitly opted out
- Pro subscription quotas and feature access quietly reduced without user notification
