Definition: Prelint is a product review tool for GitHub pull requests that checks product specifications against proposed changes. It is designed to help teams identify product drift, inconsistencies, and misalignment before changes are shipped.

What does Prelint do in a pull request workflow?

Prelint reviews product specifications on every pull request. Rather than treating a pull request only as a code change, the product is positioned to examine whether the change remains aligned with the intended product requirements and specifications.

This approach is aimed at product teams that want another review layer before a change reaches users. A pull request can introduce behavior that differs from the original plan, creates an inconsistent experience, or alters a product decision without clear alignment. Prelint is intended to surface those kinds of product-level concerns before shipping.

The central use case is specification review in the existing pull request process. Teams can use Prelint when reviewing implementation changes that may affect product behavior, requirements, or consistency across the product.

• Reviews product specifications for every pull request
• Helps detect drift between specifications and implementation
• Flags potential product inconsistencies
• Identifies possible misalignment before release
• Works with GitHub pull requests

Who is Prelint designed for?

Prelint is intended for product teams, startups, open source maintainers, and teams that organize their development process around pull requests. It may be especially relevant when a team is moving quickly and wants to keep product decisions connected to implementation work.

Teams using AI-written code or other rapid development workflows may also use Prelint as part of their review process. Faster implementation can increase the need to verify that a proposed change still follows the product specification. Prelint focuses on that product review question rather than presenting itself simply as a source code review tool.

For a startup, the service may fit a workflow where product managers, designers, and engineers need stronger visibility into whether changes reflect the agreed product direction. For an open source maintainer, it may offer a way to consider specification alignment as contributions arrive through GitHub pull requests.

Prelint does not replace the need for human decisions about priorities, requirements, or release readiness. Its stated role is to review specifications and flag relevant concerns during the pull request stage, giving the team an opportunity to assess them before merging or shipping.

How can Prelint help identify product drift?

Product drift occurs when the implemented product gradually moves away from its stated specifications, intended behavior, or agreed direction. This can happen through many individual pull requests, particularly when changes are reviewed mainly for technical correctness and not for their product consequences.

Prelint is built to catch drift by reviewing product specifications on each pull request. The goal is to identify when a proposed implementation may not match the specification, when a change creates inconsistency, or when it appears misaligned with the product direction.

For example, a team may have a documented product expectation that affects how a feature should behave across different areas of an application. A pull request can alter one part of that experience while leaving other parts unchanged. Prelint is intended to make teams aware of possible inconsistencies so they can evaluate the change before it ships.

The product's role is not described as automatically changing code or making final product decisions. Its value is in putting specification-related review into the pull request workflow, where teams can address issues while the proposed change is still under review.

Which platforms and integrations does Prelint support?

Prelint is available on the web and is built for GitHub pull request workflows. GitHub is the primary integration identified for reviewing proposed changes in pull requests.

Billing is handled through Stripe. This is relevant to teams managing prepaid review credits, automatic credit replenishment, and monthly spending controls. Stripe is listed as an integration, while GitHub is the development workflow connection used for pull request review.

A team considering Prelint should confirm that GitHub pull requests are part of its normal change-management process. The supplied product information does not identify integrations with other source control platforms or project-management systems. Organizations that rely on workflows outside GitHub should verify current compatibility directly with Prelint before adopting it.

How does Prelint pricing and billing work?

Prelint uses pay-per-review billing rather than seat-based pricing or a recurring subscription. The listed price is $1 per completed review. This model can suit teams that prefer to pay according to review activity instead of purchasing user seats.

New users can start with $10 in free credits, and a 7-day free trial is available. Prelint is not described as a free-forever product or as offering a conventional free plan. Open source projects are free, and a startup program is also available.

Prepaid credits are used for reviews. Credits do not expire according to the provided information, and teams can configure auto-recharge so their balance is replenished when needed. Monthly spending limits are available, which can help teams control usage-based costs as pull request volume changes.

• $1 for each completed review
• No seats required
• No subscription listed
• $10 in free credits at signup
• 7-day free trial available
• Prepaid credits with optional auto-recharge
• Monthly spending limits available
• Open source projects are free
• Startup program available

Because usage determines cost, teams should estimate how many completed reviews they expect from their pull request workflow. The available monthly limits can provide a budget boundary, while auto-recharge can reduce interruptions caused by depleted credits.

Why use Prelint alongside existing pull request review?

Traditional pull request review often focuses on code quality, correctness, maintainability, testing, and security. Prelint addresses a different but related review need: whether the proposed product change stays connected to the relevant specifications and intended product outcome.

For teams with frequent releases, product context can be difficult to preserve across many small changes. Prelint adds a specification-oriented checkpoint to each pull request. This can be useful when several contributors work on related product areas, when requirements change over time, or when implementation speed makes it easier for unreviewed assumptions to enter the product.

The tool may be considered by teams evaluating products such as CodiumAI, Greptile, Graphite, or Cody, although these products can have different goals and capabilities. A useful evaluation question is whether a team specifically needs product-specification review and drift detection in GitHub pull requests, rather than a broader coding, code review, or developer workflow tool.

What are the limitations of Prelint?

Prelint is not a free-forever product for general commercial use. Although it provides $10 in free credits and a 7-day trial, completed reviews are charged at the listed usage-based rate. Open source projects are an exception and are free under the stated offering.

Its billing model means costs depend on completed review volume. Teams with a high number of pull requests should use the available monthly limits and review their expected usage. The product information also notes that pricing details may vary across third-party listings, so the official Prelint pricing and billing documentation should be checked for the current terms.

Prelint is centered on web access and GitHub pull requests. The supplied information does not establish support for other code hosting platforms, offline workflows, or a broad set of development integrations. It is also a tool for flagging specification-related concerns, not a substitute for teams maintaining clear specifications or making human product decisions.
