The tools
Each one runs in your browser. The dev tools alone hold 107 small tools: JSON, JWT, Base64, hashes, SAML, certificates, colours, HTTP, PDF and image tools, pipelines and an API client.
My IP→
Your IPv4 and IPv6 address and ISP.
curl ipv4.asra.io works too.IP Lookup→
Approximate location and network owner (ISP, ASN) of any IP address.
QR Code Generator→
QR codes for links, text and Wi-Fi, with your logo and colours. PNG or SVG.
QR Code Scanner→
Read QR codes from a photo, a PDF or your camera. Finds several codes at once.
OCR→
Paste a screenshot or a photo and get its text. Runs in your browser.
Domain Checks→
DNS, DNSSEC, name servers, SPF, DMARC, DKIM, redirects and the TLS certificate of a domain.
Safe Links→
See where a link really goes before you open it: redirects, blocklists, warning signs.
Link Preview→
How your link looks in Slack, Teams, X, LinkedIn, WhatsApp and Notion, plus basic SEO checks.
Developer tools→
Hashes, JWT, Base64, JSON/YAML/CSV, text, image and PDF tools, pipelines.
API client→
Send requests from OpenAPI, Postman, HAR or curl. Keeps runs and history.
Sample APIs→
Star Wars and Petstore APIs that always answer, for tests and tutorials.
MCP server→
Use the dev tools, your pipelines, My IP and QR codes (make and read) from an AI assistant over MCP.
The night shift
Your background engine for everyday automation. Some of Asra keeps working when you are not looking:
AI assistants, any time
Claude, Cursor and other MCP clients call the tools at asra.io/tools/mcp. Your pipelines run there too.
Pipelines as scripts
Export a pipeline as one Node script and run it from cron or CI. It works offline, with the same code as the browser.
Links that keep working
Share a pipeline, a tool with its input, or a colour palette as a short link. Add a password and only ciphertext is stored.
Webhooks and email
While the dev tools are open, pipelines run on new requests in your webhooks.xyz bins and new mail in your mailt.in inboxes.
The browser tools run on your device. Close the tab and they stop; nothing is uploaded to keep them going.
About Asra
- Why the name?
- Asra stands for Automated Software & Runtime Assistant: small tools that do one job well, and pipelines that chain them.
- Do my files leave my device?
- No. The tools run in your browser. Only the few that must ask a server say so first: domain checks, the link checker, link previews, short links, and MCP.
- Who makes it?
