Analysis of grappa

Overall verdict

  • Grappa is a solid, mature parsing library for the JVM that lets developers build parsers directly in Java using a fluent, PEG-based (Parsing Expression Grammar) approach without needing a separate grammar file or code generation step.

Why this product is good

  • Uses Parsing Expression Grammars (PEG), which are unambiguous and easier to reason about than traditional context-free grammars
  • Grammars are written in pure Java as a fluent DSL, so there's no external grammar file or code-generation build step
  • Integrates naturally into existing Java/JVM projects and tooling
  • Supports parser actions, error recovery, and value stack manipulation for building ASTs
  • Successor to the popular Parboiled library, benefiting from lessons learned in that project
  • Open source and hostable/inspectable directly on GitHub

Recommended for

  • Java and JVM developers who want to build parsers without learning a separate grammar language
  • Projects needing custom domain-specific languages (DSLs) or configuration formats
  • Developers who prefer PEG semantics over ambiguous CFG-based tools like ANTLR
  • Teams that want parser logic kept inline in their codebase rather than generated
  • Prototyping and small-to-medium parsing tasks where fluent Java code is convenient

Questions & Answers

As answered by people managing grappa and ScreenRun.

How would you describe the primary audience of your product?

ScreenRun's answer:

ScreenRun is used by product teams and designers that want to share engaging videos of their apps or screens to colleagues, followers or clients.

What's the story behind your product?

ScreenRun's answer:

Many screen recording apps are either too simple (just record your screen) or complex, and none of them offered a way to quickly create engaging screen recordings by placing a few points over images or video clips to zoom and engage the person watching.

Which are the primary technologies used for building your product?

ScreenRun's answer:

Everything is web-based using modern browser APIs for video encoding and decoding. ScreenRun also uses AI from OpenAI to create automatic transcripts from your audio and video assets. But everything runs in your browser, no cloud involved for total privacy.

What makes your product unique?

ScreenRun's answer:

Entirely web-based video creation too with zooms, webcam and automatic captions. And unlike many web-based products, ScreenRun runs entirely inside your web browser without sending any data to a server. This aspect is critical for total privacy in work contexts.

Why should a person choose your product over its competitors?

ScreenRun's answer:

ScreenRun is so simple to use! And because it's web-based, you can access it from anywhere, including iPhone or Android.

  • Show HN: I made a 100% web-based and free alternative to Screen Studio
    I have no connection but seeing as these conversations often discuss alternatives I'd like to mention https://screenrun.app/. It's web based, offers plenty of features and can be had for a one-time of $40. I've only used it a handful of times however I keep coming back. - Source: Hacker News / over 1 year ago
  • Show HN: I made a free web alternative to screen studio
    I also created something web-based last year called ScreenRun https://screenrun.app It really works best in Chromium-based browser which have WebCodecs. - Source: Hacker News / almost 2 years ago

    You can do that with ScreenRun (which I developed) https://screenrun.app/. - Source: Hacker News / over 2 years ago
  • How do people create those sleek looking demos for startups?
    Others mentioned ScreenStudio (which is awesome), but if you don't need all of its features (or can't afford it at the moment), I've found ScreenRun to be a great alternative: https://screenrun.app/ It's browser-based, but there's a Mac (and Windows I think) companion app that records the screen with click-tracking for zooming (as it's not possible with browser screen sharing just yet). It's somehow limited... - Source: Hacker News / over 2 years ago
