emailA specification for building APIs in JSON.
Documentation for the application/vnd.api+json media type, a specification for APIs that use JSON.
If you’ve ever argued with your team about the way your JSON responses should be formatted, JSON:API can help you stop the bikeshedding and focus on what matters: your application.
By following shared conventions, you can increase productivity, take advantage of generalized tooling and best practices. Clients built around JSON:API are able to take advantage of its features around efficiently caching responses, sometimes eliminating network requests entirely.
the open-source database for the realtime web.
RethinkDB pushes JSON to your apps in realtime.
RethinkDB is the first open-source scalable database built for realtime applications. It exposes a new database access model, in which the developer can tell the database to continuously push updated query results to applications without polling for changes. RethinkDB allows developers to build scalable realtime apps in a fraction of the time with less effort.
While JSON is probably the most popular format for exchanging data, JSON Schema is the vocabulary that enables JSON data consistency, validity, and interoperability at scale.
JSON for Humans.
JSON5 is an extension to the popular JSON file format that aims to be easier to write and maintain by hand (e.g. for config files). It is not intended to be used for machine-to-machine communication. (Keep using JSON or other file formats for that.

Become a leader in email innovation. JMAP is the developer-friendly, open API standard for modern mail clients and applications to manage email faster.
It’s official! JMAP has been published by the Internet Engineering Task Force (IETF).
The ldap2json script allows you to extract the whole LDAP content of a Windows domain into a JSON file.
Content Management for your Codebase.
A new tool that makes Markdown, JSON and YAML content in your codebase editable by humans. Live edit content on GitHub or your local file system, without disrupting your existing code and workflows.
Valinor takes care of the construction and validation of raw inputs (JSON, plain arrays, etc.) into objects, ensuring a perfectly valid state. It allows the objects to be used without having to worry about their integrity during the whole application lifecycle.
The validation system will detect any incorrect value and help the developers by providing precise and human-readable error messages. The mapper can handle native PHP types as well as other advanced types supported by PHPStan and Psalm like shaped arrays, generics, integer ranges and more.

Biome is a performant linter for JavaScript, TypeScript, and JSX that features more than 170 rules from ESLint, TypeSCript ESLint, and other sources. It outputs detailed and contextualized diagnostics that help you to improve your code and become a better programmer!
Protocol Buffers are language-neutral, platform-neutral extensible mechanisms for serializing structured data.
Your Data Pipeline, Simplified. GlareDB: An analytics DBMS for distributed data.
Data exists everywhere: your laptop, Postgres, Snowflake and as files in S3. It exists in various formats such as Parquet, CSV and JSON. Regardless, there will always be multiple steps spanning several destinations to get the insights you need.
GlareDB is designed to query your data wherever it lives using SQL that you already know.
CLI tool that can execute SQL queries on CSV, LTSV, JSON and TBLN. Can output to various formats.
JSON for Linking Data.
Data is messy and disconnected. JSON-LD organizes and connects it, creating a better Web.
JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language.
The open source initiative to create a JSON-based standard for resumes. For developers, by developers.
jq for binary formats - tool, language and decoders for working with binary and text formats.
fq is inspired by the well known jq tool and language and allows you to work with binary formats the same way you would using jq. In addition it can present data like a hex viewer, transform, slice and concatenate binary data. It also supports nested formats and has an interactive REPL with auto-completion.
It was originally designed to query, inspect and debug media codecs and containers like mp4, flac, mp3, jpeg. But has since then been extended to support a variety of formats like executables, packet captures (with TCP reassembly) and serialization formats like JSON, YAML, XML, ASN1 BER, Avro, CBOR, protobuf. In addition it also has functions to work with URL:s, convert to/from hex, number bases, search for things etc.
Random Data Generator and API Mocking Tool (JSON / CSV / SQL / Excel).
Need some mock data to test your app? Mockaroo lets you generate up to 1,000 rows of realistic test data in CSV, JSON, SQL, and Excel formats.
JSON storage with schema validation. JSON storage bins that won't break your app.
Set up a lightweight JSON endpoint in seconds, then add a schema to edit your data safely at any time.
Free Cloud JSON Storage API.
Free data storage as a service. Pantry allows devs to store JSON for multiple apps & users. A good resource when building personal projects, apps for hackathons, and prototypes alike.
Pantry is a free service that provides perishable data storage for small projects. Data is securely stored for as long as you and your users need it and is deleted after a period of inactivity. Simply use the restful API to post JSON objects and we'll take care of the rest.
