JackHamr is the AI coding agent that ships software end-to-end. Instead of a single assistant that tries to do everything, it runs a team of specialist agents — one writes the spec, another plans the implementation, others build, test, review, and ship the code. Each agent has its own role, tools, and personality.

Agents run on hosted cloud dev environments with VS Code, Docker, SSH access, and WireGuard-encrypted networking. Close your laptop and they keep working. Talk to them with push-to-talk voice chat or type naturally. GitHub is built in — one-click clone, automatic branch-per-task, real-time commit sync, and PR creation.

Bring your own LLM keys (OpenAI, Anthropic, Google, or self-hosted) or use ours at cost — swap models mid-pipeline to use the best model for each task. Build custom orchestration pipelines and agent skills. Share agents across your organization.

Pay-as-you-go with fully itemized billing — infrastructure at cost, LLM tokens with zero markup. $10 free credit to start, no card required.

Questions & Answers

As answered by people managing TrueJson and JackHamr.

What makes your product unique?

TrueJson's answer

Every developer knows the pain—jumping between a dozen scattered JSON tools just to get one job done. One site to format, another to validate, a third to convert, each with clunky, outdated interfaces and inconsistent behavior. What should be a simple task—editing, validating, or comparing JSON—turns into a frustrating scavenger hunt across the web. Add in the constant risk of syntax errors, broken structures, and lost time, and JSON becomes less of a universal data format and more of a daily obstacle.

That’s where True JSON comes in—the all-in-one studio built for clarity, speed, and collaboration. You can edit, validate, prettify, minify, sort, and filter your data with precision. Generate or validate schemas, convert between JSON, XML, CSV, and YAML, perform diff checks, save files securely, collaborate through comments and shared access, and automate everything via API integration. Every tool you need, unified in one sleek, intelligent workspace.

Why should a person choose your product over its competitors?

TrueJson's answer

It treats JSON as a workflow, not a one-off task. It brings editing, validation, prettify/minify, sorting and filtering, schema generation and validation, format conversions (JSON ↔ XML/CSV/YAML), diffing, file saving, collaboration with comments, and API-based automation into a single, consistent workspace. The value isn’t any single feature—it’s the fact that everything works together in one place, with a modern interface and predictable behavior.

Who are some of the biggest customers of your product?

TrueJson's answer

This phase is intentional. We’re focused on validating the core workflow, refining usability, and making sure the product genuinely solves the fragmentation problem before scaling into enterprise adoption. Several teams are actively using it in day-to-day development and review workflows, and those early users are shaping what TrueJson becomes next.

We expect larger customers to follow as the product matures, but for now, the priority is building something solid, useful, and trusted—rather than chasing logos too early.

How would you describe the primary audience of your product?

TrueJson's answer

The primary audience of TrueJson is people who work with JSON frequently and operationally, not occasionally.

At the core, this includes software engineers, backend and frontend developers, and API-focused teams who deal with JSON as part of their daily workflow—config files, API payloads, responses, schemas, and integrations. For them, JSON is not just a data format but a critical dependency, and small inefficiencies or errors can quickly cascade into bugs, broken deployments, or wasted time.

Beyond individual developers, TrueJson also serves teams and technical leads—such as senior engineers, tech leads, and CTOs—who care about consistency, reliability, and collaboration. Features like schema validation, diffing, saved files, comments, and API integration make it relevant for code reviews, CI/CD pipelines, and shared standards across teams.

Finally, TrueJson is accessible to learners and non-specialist technical roles (QA engineers, product engineers, data analysts) who work with JSON but may not want to assemble and maintain a fragmented toolchain. Its value lies in reducing friction for anyone who needs JSON to be correct, readable, and trustworthy—regardless of whether they’re writing code all day or supporting systems around it.

What's the story behind your product?

TrueJson's answer

The story behind TrueJson began with a simple but persistent frustration: JSON is everywhere, yet working with it has always been fragmented. Formatting in one tool, validation in another, conversions and diffing somewhere else—each task breaking flow and adding invisible overhead that developers quietly accept as “normal.”

TrueJson was created to challenge that assumption. Instead of another single-purpose utility, it set out to give JSON a proper home—a unified, modern workspace where all common JSON tasks live together. The idea was straightforward: reduce friction, remove context-switching, and make working with JSON feel clear, reliable, and complete again.

Which are the primary technologies used for building your product?

TrueJson's answer

React & PostgreSQL, using cloudfront to host frontend app and backend being served on nextjs.
