Crabbox Gives Parallel AI Coding Agents Isolated Cloud Sandboxes to Self-Verify PRs

·1 views

A new open-source tool called Crabbox, created by OpenClaw developer Peter Steinberger, addresses a growing bottleneck in AI-assisted software development. As teams run ten or more coding agents simultaneously, the volume of pull requests has surged, shifting the main challenge from writing code to safely merging it. The core problem is that parallel agents sharing a local machine compete for the same database, ports, and Docker daemon, causing conflicts and broken environments. Crabbox solves this by provisioning each agent its own isolated cloud environment — complete with a dedicated database and dev server — so agents can run tests and attach verifiable proof to their PRs. This approach aims to let human reviewers assess evidence of working code rather than manually validating each of dozens of concurrent submissions.

Developer workflow: use public and account model catalogs before configuring AI clients

A developer writing for DEV Community outlines a structured workflow to avoid broken AI gateway configurations caused by hardcoded or outdated model IDs. The approach involves first consulting a public provider catalog such as models.dev to retrieve stable provider keys, base URLs, and expected environment variable names. Next, the developer queries the gateway's live /v1/models endpoint using their own API key to obtain an exact, current list of models accessible to their account. Only after a successful curl test against the chat completions endpoint does the developer proceed to configure IDE tools like Cline or Continue. The method addresses three common failure points: using model IDs not in the account catalog, mismatched provider keys, and stale documentation that no longer reflects the live catalog.

Dev Teams Turn to CLI Tools Over Postman as CI/CD Pipelines Demand Automation

Software development teams that traditionally relied on GUI-based API clients like Postman are increasingly shifting to command-line interface tools as their workflows move toward scripts and CI/CD pipelines. Manual API testing was becoming a bottleneck as projects scaled, prompting teams to explore CLI-first alternatives. Tools like Apidog CLI allow developers to run API tests directly from the terminal and reuse the same commands across platforms such as GitHub Actions, GitLab CI, and Jenkins. While GUI clients remain useful for exploring APIs and debugging, CLI workflows have proven easier to maintain for repeatable testing and deployment automation. The broader developer community is actively debating which CLI tool best replaces Postman, with teams still evaluating options based on features and integration needs.

Crunchyroll Suffers 100GB Data Breach via Compromised Telus Employee Account

On March 12, 2026, an attacker gained unauthorized access to Crunchyroll's systems by exploiting a compromised account belonging to a Telus Digital employee who provided outsourced support services to the anime streaming platform. Within approximately 24 hours, before access was revoked, roughly 100GB of sensitive data was exfiltrated, including customer support records, user analytics, subscription details, and potentially payment information. The breach is linked to the earlier Telus Digital security incident reported in early March 2026, highlighting how third-party contractor credentials can serve as an entry point into larger platforms. Security researchers suggest the attacker likely conducted prior reconnaissance, given the speed and volume of the data extraction. As of March 23, 2026, neither Crunchyroll nor its parent company Sony had issued any public statement regarding the incident.

India Leads World in Offline Population With 684 Million People Without Internet

Despite decades of internet expansion, roughly 37% of the global population — about 2.9 billion people — has never used the internet, according to Statista data. India tops the list of countries with the largest offline populations at 684 million people, followed by China with 336 million, even though China's offline rate is just 24%. The ranking reflects absolute numbers rather than the share of a country's population that lacks access, which is why densely populated nations dominate the list. Pakistan, Nigeria, and Ethiopia also feature prominently, with offline rates of 54%, 55%, and 81% respectively. Experts note that bridging this digital divide remains critical for advancing education, healthcare, and economic opportunity worldwide.
