Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Deep Code

  • Model choice is narrow. Bring your own key covers DeepSeek-V4-Pro and Flash plus the GLM and Mimo coding plans, and no frontier model from OpenAI, Anthropic or Google.
  • The Pro tier caps included usage at 100 Pro Credits per day rather than offering an unmetered plan.
  • Bring your own key is a paid feature, so the free tier cannot be pointed at your own DeepSeek account.
  • Desktop only, with no editor extension, web version or team seat management as of September 2026.
  • A small, young vendor with no independent review coverage yet, so there is nothing outside the vendor's own site to corroborate the cost claim.

PostHog

  • The free tier covers 1M events, 5K web session recordings and 2.5K mobile recordings per month before usage-based billing starts
  • Accounts without a card on file are limited to 1 project; adding one raises it to 6
  • Data retention is 1 year until a card is added, which extends it to 7 years
  • Support is community-only until the account is on a paid plan
  • Error tracking is capped at 100K exceptions and surveys at 1500 responses per month on the free tier
