smolanalytics vs Momentic.
An AI testing platform that catches real bugs before they ship, with plain-English tests kept as files in your codebase.
Momentic or smolanalytics?
Pick Momentic if you want the more established product, a free tier of roughly 200 test runs a month, and a vendor with named customers behind it. Pick smolanalytics if $125 a month is more than the problem is worth to you yet: it is $19 a month for 100 tested pull requests, and the first run needs no account at all.
| smolanalytics | Momentic | |
|---|---|---|
| How a test is written | One English sentence in a markdown file. No selectors, no page objects, no fixtures, no code to maintain. | Plain-English YAML files kept in the codebase. |
| Price | $19/month with 100 tested pull requests included, then 10c each. 14-day trial at those limits, no card. The agent runs on your own Anthropic key, billed to you and never resold. | Free plan at $0 forever with 2,000 credits a month, about 200 test runs, no credit card. Pay-as-you-go $125 a month for 10,000 credits, about 1,000 runs, then $0.01875 a credit. Enterprise custom. |
| What it takes to start | A URL and a sentence. No account for the first run, no GitHub App, no preview environment to build, and nothing written into your repository. | Self-serve signup, then tests live in your repository and run with the same command locally and in CI. |
| Cost of a run that passes | Recorded on the first pass, then replayed with no model call. | Their AI Action V3 drafts a flow up front, caches the resolved steps and self-heals on failure, so resolved steps also replay from cache. |
| In your editor | An MCP server your agent connects to once, so Cursor or Claude Code runs the suite and reads what broke. | MCP servers for Claude Code and Cursor. |
| Who is behind it | One person, building in public, with no customer logos to show yet. | An established vendor showing testimonials from Notion, Webflow, Quora, Retool, Runway and GPTZero. |
where Momentic is the better pick
Momentic is the more finished product and it is not close. They have named customers, a team, mobile ambitions and years of edge cases already met. Their free tier is genuinely usable at around 200 runs a month. If you are choosing infrastructure for a team that will still be using it in three years, the thing you are really buying is the vendor, and theirs is the safer bet than one person on the internet.
where smolanalytics is
Two things. Price, at $19 a month against $125, which matters when the budget is your own card. And the first run: you can get a verdict out of this product before making an account, because the runner is an npm package that takes a URL and a sentence. We also keep five verdicts apart rather than four, so a recording that stopped fitting your app is reported as stale and never coloured as a bug in your product.
How it works walks the loop from the sentence to the comment on the pull request, and the docs have the flags, the suite format and the CI step.

One sentence, on your app, tonight.
Point it at a URL that is already running and describe what should work. The first run uses the agent; once it passes it is recorded, so every run after that replays with no model at all.
