Topolog's answer

Built by a solo founder with 14 years across Meta, Media.net, Amazon and others. After watching countless projects miss deadlines, not from incompetence but from tools that gave one fake date, I set out to build a planning engine that takes uncertainty seriously. The result is Topolog: a formally total scheduling language, a deterministic Monte Carlo engine, and a Bayesian self-tuning scheduler. Built entirely solo with Claude Code and Devin as AI engineering partners. Zero VC, zero team, 100% ownership.

TryStackPick's answer:

StackPick started after comparing automation and messaging SaaS and finding that list prices hide conversation fees, seats, and billing units. The site was built to publish verified pricing and calculators so buyers can model the real bill before committing.

Topolog's answer

Anyone running a goal with real dependencies and real stakes: technical project managers, engineering managers, founders, and ambitious individuals planning complex personal projects like home renovations, album productions, or marathon training. The unifying characteristic is feeling the pain of planning tools that lie about deadlines. Topolog is for people who want to know their actual odds, not a false sense of certainty.

TryStackPick's answer:

Founders, ops and marketing teams, freelancers and agencies choosing WhatsApp Business API vendors, email marketing tools, AI voice agents, and workflow automation stacks (n8n, Make, Zapier). Anyone who needs the real monthly cost, not just a feature list.

Topolog's answer

Every other planning tool gives you one deadline, the one you'll miss. Topolog gives you the full picture: a dependency graph that knows what blocks what, a Monte Carlo completion spectrum showing your real odds, a critical path that updates as you execute, and a budget tracker tied directly to your probability of success. MS Project has critical path but no probabilistic engine. Monday and Asana have boards but no complete dependency model. AI tools hallucinate dates. Topolog computes them.

TryStackPick's answer:

Directories like G2 and Capterra aggregate reviews. TryStackPick focuses on the bill: Meta conversation fees, seats, annual vs monthly, and what “from $X” really means. Model the monthly cost before you buy the wrong plan.

Topolog's answer

Topolog treats every plan as a program. Plans are written in TOL (Total Orchestration Language), a formally total, decidable language where the scheduler and Monte Carlo engine compute dates and probabilities deterministically. The AI drafts structure but never touches the maths. You get a completion spectrum (a probability distribution over outcomes), honest deadline ranges (a floor and a ceiling, never one date you'll miss), and a Bayesian self-tuning scheduler that learns your real pace from timestamps alone. The planning language is public, you can author plans with any AI and run them through Topolog's engine.

TryStackPick's answer:

TryStackPick publishes verified SaaS pricing with the billing unit included — not just list price. You get independent comparisons, real-cost calculators (WhatsApp API, automation stacks, email tools), and free n8n workflow templates. Rankings are not sponsored.

Topolog's answer

Topolog is a TypeScript-first web app built around a custom stochastic-planning engine:

Frontend: Next.js 15 (App Router) with React 18 and TypeScript, styled with Tailwind CSS. The interactive plan canvas uses dagre / ELK (elkjs) for graph layout.

Core engine: an in-house DSL ("TOL") plus a Monte Carlo stochastic-forecasting engine, written in pure isomorphic TypeScript so it runs identically on the server and in the browser.

Backend & data: Supabase (PostgreSQL, auth, and SSR), with the API layer on Next.js route handlers. Stripe handles billing.

AI authoring: a model-router layer that calls GPT (OpenAI), and Mistral for plan authoring and review.

Infra & quality: deployed on Vercel (Analytics + Speed Insights), error monitoring via Sentry, and tested with Jest + Playwright.

TryStackPick's answer:

Python static site generator, HTML/CSS/JavaScript, Cloudflare Pages (and Pages Functions for affiliate redirects), SQLite-backed click tracking, and n8n for the free workflow templates.
