## Models.dev

Models.dev exists to answer a very practical developer question: which model should I use, and what will it cost? The site organises every entry under a canonical identifier in the form provider/model, so the same model served by several providers can be compared directly rather than guessed at. Columns cover context window, maximum output, whether input and output are supported, reasoning, tool calling, structured output, temperature control, open versus closed weights, price per million tokens, and release and update dates.

Because model releases move fast, the catalogue is built to stay current, with sortable and searchable tables that let you scan by lab or provider and filter down to what matters. Entries include both closed flagship models and open-weight alternatives, making it useful for cost planning as well as capability research.

The project is open source and free to use, and it is intended to be consumed programmatically. Developers can pull the catalogue into their own tooling through a JSON API or a type-safe SDK, which makes it a practical backend for dashboards, routing logic, or internal cost calculators rather than just a reference page to browse.

**Pricing & Plans:** Models.dev is free and open source. It is a reference database, so the prices it lists are the per-million-token rates charged by the model providers themselves, not a fee for using the site.

- **Canonical model identifiers:** Every model uses a consistent provider/model format so the same model across providers can be compared directly.
- **Specification comparison:** Side-by-side context window, output limit, reasoning, tool calling, structured output, and temperature support.
- **Pricing transparency:** Input and output prices per million tokens listed alongside release and update dates.
- **Open and closed models:** Covers closed flagship APIs and open-weight models from many labs in one sortable catalogue.
- **Developer access:** Consume the catalogue through a JSON API or a type-safe SDK for your own tools and dashboards.

**Strengths:** Free and open source with no account required; Consistent canonical identifiers make cross-provider comparison reliable; Covers pricing, limits, and capabilities in one sortable table; Available as a JSON API and type-safe SDK for programmatic use

**Limitations:** It is a reference catalogue, not an inference or hosting service; Data quality depends on community and maintainer updates keeping pace with releases; Interface is aimed at developers and offers little guidance for non-technical users

## Respond.io

Most B2C companies end up chatting with customers across half a dozen apps, and the result is missed messages, duplicated work and no single view of the relationship. Respond.io addresses that by consolidating WhatsApp, TikTok, Instagram, Facebook Messenger, Telegram, Viber, Line, email and website chat into one shared inbox. Every contact, conversation and deal lives in one place, colleagues can assign and hand off threads internally, and a built-in CRM keeps lead status, tags, custom fields and lifecycle stage attached to the person rather than to the app they messaged from.

AI is woven through the platform rather than bolted on. AI agents greet new enquiries, ask qualifying questions, route the conversation to the right team or salesperson, and take care of repetitive requests like order status or opening hours. An AI-powered contact automation layer can follow up with leads that went quiet, tag conversations automatically and trigger workflows when a customer replies. For marketing teams, broadcast campaigns and click-to-chat links on ads let one message reach thousands of customers while replies still land in a human-operated inbox with full context.

Deployment is channel-agnostic and aimed at operations rather than engineering. Businesses connect their own WhatsApp Business API number or social accounts, build workflows with a no-code builder, and add teammates with role-based permissions. Multi-channel reporting shows response times, resolution rates and campaign performance per channel, which helps teams spot where the real bottlenecks are. Pricing is freemium: a free trial and entry-level tiers exist, with paid plans scaling by number of users and monthly active contacts, and WhatsApp messaging costs handled separately by the provider.

**Pricing & Plans:** Freemium with a free trial. Paid tiers scale by users and monthly active contacts, and WhatsApp messaging fees are billed separately by the channel provider.

- **Unified team inbox:** Bring WhatsApp, TikTok, Instagram, Facebook, Telegram, email and web chat into one shared inbox so no customer thread gets lost between apps.
- **AI agents and automation:** AI agents qualify leads, answer routine questions, route to the right teammate and follow up automatically when conversations go quiet.
- **Contact lifecycle CRM:** Track tags, custom fields, lead status and lifecycle stage per contact, and move deals through a pipeline without a separate CRM.
- **Broadcast campaigns and click-to-chat:** Reach thousands of customers with one message, and capture new leads directly from social ads and website links.
- **Reporting and analytics:** Measure response and resolution times, agent workload and campaign performance across every connected channel.

**Strengths:** Genuinely broad channel coverage, including WhatsApp Business API and social apps B2C customers actually use; AI agents handle routine qualification and follow-up work alongside, not instead of, human teammates; Built-in contact CRM and pipelines reduce the need for a separate tool; Multi-channel analytics make it easier to prove where revenue comes from

**Limitations:** WhatsApp messaging costs are separate from the platform subscription and can add up; Pricing scales with monthly active contacts, so high-volume contact lists get expensive; Teams wanting deep custom workflow logic may hit the limits of the no-code builder
