The problem
Kids reach YouTube and ads even with content filters on. Built-in tools are complex, ecosystem-locked, or bypassed. Managing multiple computers means a separate chore on each one.
What it does
KidSplorer puts parents in complete control with a whitelist-only browser. Children can only visit sites you've approved. Manage everything remotely, approve site requests from your phone with one tap, and never manually update software again.
- Only approved sites are accessible — everything else is blocked
- Approve a child's site request from your phone — one tap, no login needed
- Set allowed browsing hours by day — browser locks automatically outside those times
- One admin dashboard manages all computers — home, school, or church
- Silent auto-updates — you never need to install an update manually
- No child personal data collected — access control, not surveillance
Best for: parents, homeschool families, small schools, churches, and libraries.
MyCostBase — adjusted cost base tracking for Canadian investors
The problem
If you hold investments across multiple Canadian brokerages, tracking pooled adjusted cost base by hand is tedious and error-prone. Get it wrong and your capital gains calculations are off — which matters at tax time.
What it does
MyCostBase tracks pooled ACB across accounts, brokerages, and distribution events accurately — including DRIP shares, return of capital, in-kind transfers, and FX on USD holdings — so your year-end numbers match your T5008 slips.
- Pooled ACB calculation across multiple accounts and brokerages
- Support for DRIP shares, return of capital, and in-kind transfers
- FX handling for USD-denominated holdings reported in CAD
- Year-end reconciliation trail that matches your T5008 slips
Not the right fit for US investors or portfolio performance analytics — MyCostBase is purpose-built for Canadian ACB and capital gains tracking.

The problem
Tab-switching for common dev tasks — encoding a string, checking a hash, formatting a JSON blob, looking up a subnet — adds up. These are one-off lookups that don't warrant an IDE but constantly interrupt the work that does.
What it does
CodersTool is a browser-based toolbox — converters, validators, calculators, and utilities covering encoding, security hashing, SQL, networking, data formats, and HTTP. Most tools run instantly in the browser. A Chrome Extension brings the most-used ones to any tab.
- Encoding & Unicode converters — UTF-8/16/32, Base64, Hex to ASCII
- Security & hashing — Bcrypt, Argon2, SHA, AES, JWT decode, BIP39
- SQL syntax checker, formatter, and test data generator
- DNS lookup, subnet calculator, SSL checker, WHOIS
- JSON, XML, YAML formatters and HTTP header/redirect tools
- Chrome Extension for quick access from any tab
Not the right fit if you need an IDE or code editor — CodersTool handles quick lookups and conversions, not writing or running code.
The problem
After a payment succeeds, the app sometimes fails silently — access not granted, credits not applied, subscription state not updated. No one finds out until the customer complains or churns. Small SaaS teams can't afford to build internal incident tooling from scratch.
What it does
SendPromptly detects when Stripe or Shopify payments succeed but the expected outcome doesn't happen — access granted, credits applied, subscription updated. It catches the gap automatically and gives your team a safe way to repair it through signed callbacks, without manual intervention or customer support tickets.
- Monitors Stripe Billing/Checkout and Shopify orders for silent fulfillment failures
- Signed HMAC-SHA256 repair callbacks — safe automated fixes, no manual intervention
- Idempotent deduplication on provider event ID — no double-repairs
- Full audit trail with actor and timestamp on every incident
- Project-scoped API keys and encrypted metadata storage (opt-in)
Not the right fit for teams using a managed billing platform that handles fulfillment internally — SendPromptly is for teams running custom Stripe or Shopify fulfillment logic.
The problem
SEO and PPC agencies spend 3+ hours per client rebuilding the same monthly update — copying metrics across dashboards, re-explaining context that was already written last month, and chasing next actions buried in post-call emails.
What it does
TrackToGrow gives agencies a repeatable monthly update workflow. Enter metrics, write the narrative, publish a clean shareable link your client can open without logging in. Teams consistently cut reporting time to under 30 minutes per client without losing communication quality.
- Define 3–5 key metrics per client — flags on track, at risk, or off track
- Write the expert narrative behind the numbers in one consistent format
- Assign next actions with owners — no more follow-ups lost after the call
- Publish a shareable read-only link — no client login, no PDF, no dashboard
- Built for agencies managing 5–40 retained clients
Not the right fit for enterprise BI teams or solo freelancers — TrackToGrow is built for small SEO and PPC agencies with recurring monthly reporting commitments.
