I'm a TypeScript dev with decent backend experience and I'm building a booking system for a client with around 3,000 users. I've only ever worked on teams where every PR got two human reviewers and honestly I liked that setup a lot. This time it's just me and Claude Code writing most of the boilerplate. My hesitation is cost and whether it's worth it. Coderabbit is $24 a month which is fine for one person, but I'm not sure a reviewer that only sees the diff catches what a second human would have. Strict tsc plus typescript-eslint is obviously attractive because it's free, but I've been on enough projects to know the type checker doesn't care if my auth middleware is wired to the wrong route. For those running solo TypeScript apps in production: which did you go with and why? I'm interested in real experience rather than tool comparison posts. One clarification: for a single client the risk is low. My worry is if this grows into a multi tenant product and I've shipped 6 months of code nobody but me and a model ever read.
