Goast.ai

Most AI code assistants write new code. Goast.ai is an AI bug fixing tool that goes the other way: it analyzes errors, finds the root cause, and produces a step-by-step resolution plan plus an AI-generated pull request for developers.

That narrow focus suits teams who spend more time on production errors than on greenfield features.

Pricing has three tiers.

The free 30-day trial covers 50 root cause analyses, 10 resolution plans and 10 pull requests, though you need to connect an error monitoring tool to use it.

Pro costs $499 a month, raises the limits to 100 analyses, 50 plans and 50 pull requests, and adds usability bug fixing through prompts.

Enterprise offers unlimited usage, custom integrations and usage-based pricing.

The Pro price is steep for a solo developer, so Goast.ai looks made for teams.
