Rare cards by language

SR and above, grouped by language. Stats from the current card pool (snapshot 2026-10-30).

Language matters in Repo Gacha. Every card carries its language as an attribute, and some combos and skills care about it: a Rust card can rewrite a fallen tiny card, and stacking one ecosystem switches on Monorepo. Here are some of the rarest cards in each language.

TypeScript

n8n-io/n8n SSR

TypeScript · ★ 209,109 · ATK 94 / DEF 87 · open the card

Workflow automation with hundreds of integrations. The card for people whose job is connecting two things that should already be connected.

Rust

rust-lang/rust SSR

Rust · ★ 120,835 · ATK 90 / DEF 89 · open the card

The compiler itself. High ATK, high DEF, and a borrow checker that reviews your Stack before the boss does.

rustdesk/rustdesk UR

Rust · ★ 127,580 · ATK 90 / DEF 73 · open the card

Self-hosted remote desktop. The card your family will ask you to install on their computer "real quick".

Python

TheAlgorithms/Python UR

Python · ★ 225,700 · ATK 95 / DEF 63 · open the card

Every algorithm you were asked about in an interview, implemented in Python and lovingly linted by thousands of contributors.

Go

golang/go UR

Go · ★ 139,443 · ATK 91 / DEF 84 · open the card

The Go language. Simple, fast, and the only language whose error handling has its own genre of conference talk.

ollama/ollama UR

Go · ★ 185,338 · ATK 93 / DEF 74 · open the card

Run large language models on your own machine. The card that turns your laptop fan into a jet engine.

C

Genymobile/scrcpy UR

C · ★ 153,571 · ATK 92 / DEF 59 · open the card

Mirror and control an Android phone from your desktop. Beloved by everyone who has ever tried to type a long message on a phone.

C++

ggml-org/llama.cpp SSR

C++ · ★ 132,839 · ATK 91 / DEF 84 · open the card

LLM inference in plain C/C++. Proof that "it runs on my machine" can include a language model.

Java

NationalSecurityAgency/ghidra SSR

Java · ★ 96,068 · ATK 88 / DEF 83 · open the card

A full reverse-engineering suite, released in public by the people you'd least expect. One of the few cards whose DEF comes with a security clearance.

Swift

swiftlang/swift SR

Swift · ★ 70,529 · ATK 86 / DEF 91 · open the card

The Swift language and compiler. Its DEF is one of the highest in the pool, because compilers are big and so is ambition.

Haskell

jgm/pandoc SSR

Haskell · ★ 46,755 · ATK 83 / DEF 72 · open the card

The universal document converter. Markdown in, anything out, and a Haskell codebase that quietly powers half the world's documentation pipelines.

koalaman/shellcheck SR

Haskell · ★ 40,259 · ATK 82 / DEF 56 · open the card

The linter that tells you to quote your variables. In battle it silences the cheapest enemy card, which feels exactly like a code review.

Elixir

phoenixframework/phoenix SR

Elixir · ★ 23,211 · ATK 77 / DEF 65 · open the card

The web framework that promises "peace of mind from prototype to production". The rare card that is calm under load.

Zig

ghostty-org/ghostty SR

Zig · ★ 63,015 · ATK 85 / DEF 74 · open the card

A fast, native terminal emulator. The card for people who have opinions about font rendering, which is everyone who uses it.

tigerbeetle/tigerbeetle SR

Zig · ★ 17,275 · ATK 75 / DEF 71 · open the card

A financial transactions database built for safety. Its DEF is high because nobody wants their ledger to be a fun card.

PHP

nextcloud/server SR

PHP · ★ 37,356 · ATK 81 / DEF 99 · open the card

Your own cloud: files, calendar, contacts and more, self-hosted. Maximum DEF, and the patience of everyone who maintains a home server.

Shell

ohmyzsh/ohmyzsh UR

Shell · ★ 190,244 · ATK 93 / DEF 62 · open the card

The framework that made a million terminals colourful. Two thousand contributors and one prompt theme you will change every week.
